A team of researchers led by professors from two Houston universities has discovered new methods that help stabilize an emerging technique known as carbon dioxide reduction reaction, or CO2RR, that is used for carbon capture and utilization processes.

The team led by Rice University’s Haotian Wang, associate professor in chemical and biomolecular engineering, and Xiaonan Shan, associate professor of electrical and computer engineering at University of Houston, published its findings in a recent edition of the journal Nature Energy.

CO2RR is an emerging carbon capture and utilization technique where electricity and chemical catalysts are used to convert carbon dioxide gas into carbon-containing compounds like alcohols, ethylene, formic acids or carbon monoxide, according to a news release from Rice. The result can be used as fuels, chemicals or as starting materials to produce other compounds.

The technology is used in commercial membrane electrode assembly (MEA) electrolyzers to convert carbon dioxide into valuable compounds, but the technology isn’t perfected. A significant challenge in CO2RR technology has been the accumulation of bicarbonate salt crystals on the backside of the cathode gas diffusion electrode and within the gas flow channels. The salt precipitates block the flow of carbon dioxide gas through the cathode chamber, which reduce the performance and can cause a failure of the electrolyzers.

The goal in the study was to understand why and how bicarbonate salts form during this reaction. The Rice and UH teams worked together using operando Raman spectroscopy, which is a technique that allows researchers to study the structure of materials and any precipitates that adhere to them while the device is functioning.

“By utilizing operando Raman spectroscopy and optical microscopy, we successfully tracked the movement of bicarbonate-containing droplets and identified their migration pattern,” Shan said in the release. “This provided us the information to develop an effective strategy to manage these droplets without interrupting system stability.”

Next, the team worked to prevent the salt crystals from forming. First, they tested lowering the concentration of cations, like sodium or potassium, in the electrolyte to slow down the salt formation. This method proved to be effective.

They also coated the cathode with parylene, a synthetic polymer that repels water, like Teflon, which also notably improved the stability of the electrolyzer and prevented salt accumulation.

“Inspired by the waxy surface of the lotus leaf which causes water droplets to bead up and roll off, carrying off any dirt particles with it and leaving the leaf’s surface clean, we wondered if coating the gas flow channel with a nonstick substance will prevent salt-laden droplets from staying on the surface of the electrodes for too long and, therefore, reduce salt buildup.” Wang said in the release.

According to Wang, these relatively simple discoveries can extend the operational lifespan of CO2RR systems from a few hundred hours to over 1,000 hours.

The findings also have major implications for commercial applications, Shan added.

“This advancement paves the way for longer-lasting and more reliable (CO2RR) systems, making the technology more practical for large-scale chemical manufacturing,” Shan said in the release. “The improvements we developed are crucial for transitioning CO2 electrolysis from laboratory setups to commercial applications for producing sustainable fuels and chemicals.”

ExxonMobil to move legal home to Texas, citing business-friendliness

ExxonMobil is poised to move its legal headquarters from New Jersey to Texas in search of a more friendly business environment, the company announced March 10.

The board of directors for the largest U.S.-based oil producing company, which already runs its operations from the Houston suburb of Spring, unanimously recommended to its shareholders that they vote to redomicile the company in Texas.

Shareholders will vote on the change at the company’s annual meeting on May 27. If successful, it will move Exxon’s legal home for the first time since it registered in New Jersey in 1882 as Standard Oil Company — the company later changed its name to Exxon, then merged with Mobil Oil Corp.

“Over the past several years, Texas has made a noticeable effort to embrace the business community,” ExxonMobil Chair and CEO Darren Woods wrote in a statement Tuesday. “In doing so, it has created a policy and regulatory environment that can allow the company to maximize shareholder value. Aligning our legal home with our operating home, in a state that understands our business and has a stake in the company’s success, is important.”

The proposed move will not affect the company’s business operations or employee locations, the company said.

ExxonMobil has been headquartered in Texas since 1989, and about 30% of its employees currently work in the state.

The location of a company’s incorporation dictates the legal, tax and regulatory landscape for the business.

Exxon would join Tesla, Space X and Coinbase as major U.S. companies to redomicile in Texas in recent years as the state moves to become more business friendly.

In 2023, the Legislature passed and Gov. Greg Abbott signed a law that created the Texas Business Court and the 15th Court of Appeals, specialized legal venues designed to handle business and commercial disputes. Those courts began operating in 2024.

Last year, the Legislature also approved a law that made it more difficult to sue board members of companies incorporated in Texas.

“Freed from the stranglehold of over-regulation, Texas is where global brand leaders thrive and jobs for hardworking Texans grow,” Abbott wrote in a Tuesday statement. “I thank ExxonMobil for their decision to redomicile in Texas and for their long-standing partnership with our state. With this decision, Texas will further dominate the corporate landscape and ensure our economic growth reaches new heights.”

Exxon noted the creation of the business courts and other recent legal reforms made by Texas in its statement announcing the decision.

“In making its recommendation, the Board considered Texas’ legal and regulatory environment, including its modernized business statutes and the Texas Business Court, which is designed to resolve complex disputes efficiently,” the statement said.

Texas has benefited from growing frustration among company executives with traditional corporate havens of New Jersey and Delaware. New Jersey sued Exxon in 2022, alleging the company contributed to climate change, which forced the state to pay for cleanup after natural disasters. The lawsuit was dismissed last year.

Delaware remains the nation’s top state for U.S. companies’ legal home.

Coinbase’s CEO wrote last year that the company was reincorporating from Delaware to Texas because the Lone Star State’s legal framework is more predictable and efficient. Tesla reincorporated from Delaware to Texas after a 2024 court ruling ordered CEO Elon Musk to give up a compensation package, finding that the package’s shareholder approval process was “deeply flawed.”
