CO2 Electrolysis Paired with Glycerol Oxidation on Transition-Metal Single-Atom Catalysts

Attila Kormányos, Adrienn Szirmai, Yuhan Chen, Eamonn Murphy et autres

Abstract Pairing the carbon dioxide reduction process with the electrocatalytic oxidation of glycerol (GOR), instead of the typically applied oxygen evolution reaction, can substantially decrease the cell voltage while forming high-value products at both electrodes. In this contribution, glycerol oxidation was driven …

Immobilization method dictates the photoelectrochemical glycerol oxidation performance of semiconductor catalyst assemblies

Ádám Balog, Gergely Ferenc Samu, Dávid Fekete, Cintia Hajdu et autres

Photoelectrochemistry provides a direct route to convert sunlight into valuable chemicals. However, high-performance photoelectrode architectures often require complicated synthesis steps and expensive instrumentation. Although physical immobilization (e.g., spray coating) of catalyst particles on semiconductors seems to be a simple and universal approach, …

Scaling Low-Temperature CO2-to-Syngas Electroreduction: Failure Modes, Engineering Bottlenecks, and Mitigation Strategies

Senthilkumar Pachamuthu, Jing Gao, Adnan Ozden, Ulrich Legrand et autres

Abstract Low-temperature CO2 electroreduction (CO2eR) to syngas offers tunable H2:CO ratios and a renewable route to decarbonized syngas production, yet catalyst-level advances rarely translate to scalable, durable systems. This review addresses that disconnect with a systems-engineering perspective. We first establish the component …
