Instead of releasing carbon dioxide emissions into the atmosphere researchers want to capture and convert it into carbon monoxide.

Turning carbon dioxide into industrial chemicals applied in everything from synthetic fuels to plastics and pharmaceuticals is costly. But new research demonstrates it does not have to be.

For context, a study from University of Mississippi researcher Ahmed Badreldin and Carter Racine, a mechanical engineering doctoral student at Texas A&M University, demonstrated a simpler, lower-cost way to produce carbon-recycling catalysts at much larger scales, addressing one of the biggest barriers to commercial adoption. They published their results in the journal ACS Omega.

"There are plenty of companies out there, particularly startups in the electrochemical energy-conversion space, that have the infrastructure for this ready, but they're reaching a bottleneck, " remarked Badreldin, Ole Miss assistant professor of chemical engineering.

"Most advanced nanostructured catalysts are being developed right now at the milligram scale – often around 50 to 100 milligrams – and they're relying on conventional, silver-based catalysts. We have successfully showcased that in a single synthesis, we can create 75-gram batches without losing performance of advanced single-atom electrocatalysts."

Carbon dioxide accounts for 80% of the nation's greenhouse gas emissions from human activities, and the U.S. Produced some 5 billion metric tons of carbon dioxide in 2022, the most recent year for which the Centers for Disease Control and Prevention provides data.

Instead of releasing carbon dioxide emissions into the atmosphere, where the gas contributes to climate change, researchers want to capture and convert it into carbon monoxide. While poisonous to humans, carbon monoxide is an industrial building block applied to manufacture fuels, plastics, pharmaceuticals and other products.

In the hydrocarbon industry, they often talk about syn gas, which is just carbon monoxide and hydrogen mixed together, Racine remarked. When they're mixed together, it's essentially a building block for producing other chemicals that we need.

"It really is the simplest form of carbon we can have, and if we pair it with green hydrogen, we can use those building blocks to make all of the chemicals that would otherwise be produced with virgin fossil fuels."

Turning carbon dioxide into carbon monoxide is already feasible, but the slow rate of catalyst creation has been a stumbling block for efforts to produce carbon recycling industry-friendly, Racine noted.

"If you're making 100 milligrams per batch, it would take you a year or more to make enough catalysts to cover 10 square meters of area, " he remarked. "If we can make 75 grams in a batch – like we are in this study – we can make enough catalysts for a large commercial implementation of these technologies in a few days."

Producing catalysts in small batches additionally requires more time and energy, thus, increasing costs.

"'How much electricity do we need to do this?' is the biggest consideration, " Racine remarked. "Being able to do this in larger batches proves the logistics and the feasibility of doing it at a large scale."

Using a nickel-and-iron single-atom catalyst design, the new catalyst could reduce the cost of recycling to $145 per ton, some $255 below the current market cost. It would additionally have around 25% fewer emissions than current methods.

The goal right now is largely driven by national security, Badreldin remarked. This could allow the U.S. To establish its own supply chain for the fuels and chemicals that are essential to industry.

"Most of the chemical industries around the world are centralized somewhere, but with this technology, we can decentralize that."

Meanwhile, the setup for the electrochemical process is modular, meaning firms can scale the amount of carbon they recycle to that industry's need, he stated.

If you are, for instance, trying to use CO2 to make ethylene or ethanol, which you may need for your production line, you don't have to have a huge electrochemical plant or buy the product from somewhere that does, Badreldin remarked. You can have a stack sized just sizeable enough to produce the volume you need. That's something you can't do with the conventional setup.

For context, the last hurdle to clear is making the process stable enough for industrial employ, Racine stated.

Our future research is looking at figuring out long-term stability, he remarked. Major oil and gas plants and other industrial facilities, they run 24/7 for concerning 350 days of the year and take a week or so off to do maintenance. If we want those facilities to employ this, we have to have a model that can operate for almost a year.
