Single-Atom Indium Catalyst Enables Efficient CO2-to-Methanol Conversion

ETH Zurich researchers engineered a hafnium oxide-supported single-atom indium catalyst that dramatically lowers the energy required to convert CO2 and hydrogen into methanol, with each indium atom acting as an active site. This design offers clearer insight into reaction mechanisms, improved efficiency over nanoparticle catalysts, and durability under industrial conditions, potentially accelerating climate-friendly methanol production if powered by renewables.

Three-Layer Electrode Bridges CO2 Capture and Conversion to Formic Acid

A three-layer gas-diffusion electrode can simultaneously capture CO2 from real-world gas streams (including dilute ambient air and simulated flue gas) and convert it directly into formic acid, outperforming existing electrodes under realistic conditions. The device combines a CO2-selective capture layer, a gas-permeable carbon paper, and a tin(IV) oxide catalyst, offering a simpler, on-site route to carbon utilization with potential adaptation to other greenhouse gases in the future.

Innovative Acid Bubbles Simplify CO2 to Fuel Conversion

Researchers at Rice University developed a simple method using acid bubbles to significantly improve the stability and lifespan of CO2 electroreduction systems, enabling over 4,500 hours of stable operation by preventing salt buildup that typically causes system failure, thus advancing scalable and sustainable fuel production from CO2.

Revolutionary Catalyst Converts CO2 into Valuable Resource, Cornell Researchers Discover.

Researchers at the Tata Institute of Fundamental Research have developed a highly efficient and stable copper-based catalyst for converting CO2 to CO, with a CO productivity of 5350 mmol g−1 h−1 and 99.8% selectivity. The catalyst remained stable for over 200 hours, and in-situ studies highlighted the importance of defect sites in tuning strong metal-support interactions. The approach may lead to the design of catalytic systems using various active sites and defective supports.
