Researchers at Rice University have developed a catalyst that could render steam methane reforming, or SMR, entirely emission-free by using light rather than heat to drive the reaction.

The researchers believe the work could prove to be a breakthrough for extending catalyst lifetimes. This will improve efficiencies and reduce costs for a number of industrial processes that are affected by a form of carbon buildup that can deactivate catalysts called coking.

The new copper-rhodium photocatalyst uses an antenna-reactor design. When it is exposed to a specific wavelength of light it breaks down methane and water vapor without external heating into hydrogen and carbon monoxide. The importance of this is it is a chemical industry feedstock that is not a greenhouse gas. Rice’s work also shows that the antenna-reactor technology can overcome catalyst deactivation due to oxidation and coking by employing hot carriers to remove oxygen species and carbon deposits, which effectively regenerates the catalyst with light.

The new SMR reaction pathway build off a 2011 discovery from Peter Nordlander, Rice’s Wiess Chair and Professor of Physics and Astronomy and professor of electrical and computer engineering and materials science and nanoengineering, and Naomi Halas. They are the authors on the study about the research that was published in Nature Catalysis. The study showed that the collective oscillations of electrons that occur when metal nanoparticles are exposed to light can emit “hot carriers” or high-energy electrons and holes that can be used to drive chemical reactions.

“This is one of our most impactful findings so far, because it offers an improved alternative to what is arguably the most important chemical reaction for modern society,” Norlander says in a news release.

The research was supported by Robert A. Welch Foundation (C-1220, C-1222) and the Air Force Office of Scientific Research (FA9550-15-1-0022) with the Shared Equipment Authority at Rice providing data analysis support.

“This research showcases the potential for innovative photochemistry to reshape critical industrial processes, moving us closer to an environmentally sustainable energy future,” Halas adds.

Hydrogen has been studied as it could assist with the transition to a sustainable energy ecosystem, but the chemical process responsible for more than half of the current global hydrogen production is a substantial source of greenhouse gas emissions.Hydrogen is produced in large facilities that require the gas to be transported to its point of use. Light-driven SMR allows for on-demand hydrogen generation,which researchers believe is a key benefit for use in mobility-related applications like hydrogen fueling stations or and possibly vehicles.

Houston startup founders report on clean energy tech efficacy

seeing results

A team from Rice University has uncovered an inexpensive, scalable way to produce clean-burning hydrogen fuel.

In research published this month in the journal Science, researchers from Rice’s Laboratory for Nanophotonics, in partnership with Syzygy Plasmonics Inc. and Princeton University’s Andlinger Center for Energy and the Environment, detail how they converted ammonia into carbon-free fuel using a light-activated catalyst.

The new catalyst separates the liquid ammonia into hydrogen gas and nitrogen gas. Traditional catalysts require heat for chemical transformations, but the new catalyst can spur reactions with just the use of sunlight or LED light.

Additionally, the team showed that copper-iron antenna-reactors could be used in these light-driven chemical reactions, known as plasmonic photocatalysis. In heat-based reactions, or thermocatalysis, platinum, and related precious (and expensive) metals like palladium, rhodium, and ruthenium are required.

“Transition metals like iron are typically poor thermocatalysts,” Naomi Halas, a co-author of the report from Rice, said in a statement. “This work shows they can be efficient plasmonic photocatalysts. It also demonstrates that photocatalysis can be efficiently performed with inexpensive LED photon sources.”

Halas, Rice's Stanley C. Moore Professor of Electrical and Computer Engineering, was joined on the project by Peter Nordlander, Rice’s Wiess Chair and Professor of Physics and Astronomy, and Rice alumni and adjunct professor of chemistry Hossein Robatjazi. Emily Carter, the Gerhard R. Andlinger Professor in Energy and Environment, represented Princeton University.

“These results are a great motivator," Carter added. "They suggest it is likely that other combinations of abundant metals could be used as cost-effective catalysts for a wide range of chemical reactions.”

Houston-based Syzygy, which Halas and Nordlander founded in 2018, has licensed the technology used in the research and has begun scaled-up tests of the catalyst in the company’s commercially available, LED-powered reactors. According to Rice, the test at Syzygy showed the catalysts retained their efficiency under LED illumination and at a scale 500 times larger than in tests in the lab setup at Rice.

“This discovery paves the way for sustainable, low-cost hydrogen that could be produced locally rather than in massive centralized plants,” Nordlander said in a statement.

Earlier this month, Syzygy closed its $76 million series C round to continue its technology development ahead of future deployment/

Houston is home to many other organizations and researchers leading the charge in growing the hydrogen economy.

Earlier this year, Mayor Sylvester Turner announced he's determined to position the city as hub for hydrogen innovation as one of the EPA's Regional Clean Hydrogen Hubs. Organizations in Texas, Southwest Louisiana and the surrounding Gulf Coast region, known and HyVelocity Hub, also announced this month that it would be applying for the regional funding.

And according to a recent report from The Center for Houston's Future, the Bayou City is poised to "lead a transformational clean hydrogen hub with global impact."

Intuitive Machines to acquire NASA-certified deep space navigation company

space deal

Houston-based space technology, infrastructure and services company Intuitive Machines has agreed to buy Tempe, Arizona-based aerospace company KinetX for an undisclosed amount.

The deal is expected to close by the end of this year, according to a release from the company.

KinetX specializes in deep space navigation, systems engineering, ground software and constellation mission design. It’s the only company certified by NASA for deep space navigation. KinetX’s navigation software has supported both of Intuitive Machines’ lunar missions.

Intuitive Machines says the acquisition marks its entry into the precision navigation and flight dynamics segment of deep space operations.

“We know our objective, becoming an indispensable infrastructure services layer for space exploration, and achieving it requires intelligent systems and exceptional talent,” Intuitive Machines CEO Steve Altemus said in the release. “Bringing KinetX in-house gives us both: flight-proven deep space navigation expertise and the proprietary software behind some of the most ambitious missions in the solar system.”

KinetX has supported deep space missions for more than 30 years, CEO Christopher Bryan said.

“Joining Intuitive Machines gives our team a broader operational canvas and shared commitment to precision, autonomy, and engineering excellence,” Bryan said in the release. “We’re excited to help shape the next generation of space infrastructure with a partner that understands the demands of real flight, and values the people and tools required to meet them.”

Intuitive Machines has been making headlines in recent weeks. The company announced July 30 that it had secured a $9.8 million Phase Two government contract for its orbital transfer vehicle. Also last month, the City of Houston agreed to add three acres of commercial space for Intuitive Machines at the Houston Spaceport at Ellington Airport. Read more here.

2 Texas cities named on LinkedIn's inaugural 'Cities on the Rise'

jobs data

LinkedIn’s 2025 Cities on the Rise list includes two Texas cities in the top 25—and they aren’t Houston or Dallas.

The Austin metro area came in at No. 18 and the San Antonio metro at No. 23 on the inaugural list that measures U.S. metros where hiring is accelerating, job postings are increasing and talent migration is “reshaping local economies,” according to the company. The report was based on LinkedIn’s exclusive labor market data.

According to the report, Austin, at No. 18, is on the rise due to major corporations relocating to the area. The datacenter boom and investments from tech giants are also major draws to the city, according to LinkedIn. Technology, professional services and manufacturing were listed as the city’s top industries with Apple, Dell and the University of Texas as the top employers.

The average Austin metro income is $80,470, according to the report, with the average home listing at about $806,000.

While many write San Antonio off as a tourist attraction, LinkedIn believes the city is becoming a rising tech and manufacturing hub by drawing “Gen Z job seekers and out-of-state talent.”

USAA, U.S. Air Force and H-E-B are the area’s biggest employers with professional services, health care and government being the top hiring industries. With an average income of $59,480 and an average housing cost of $470,160, San Antonio is a more affordable option than the capital city.

The No. 1 spot went to Grand Rapids due to its growing technology scene. The top 10 metros on the list include:

  • No. 1 Grand Rapids, Michigan
  • No. 2 Boise, Idaho
  • No. 3 Harrisburg, Pennsylvania
  • No. 4 Albany, New York
