Current oxidative dehydrogenation processes are based on petroleum cracking that is indirect, environmentally unfriendly, and energy intensive. Here, the authors discover that subnanometer sized cobalt oxide clusters are active for oxidative dehydrog

Preferential oxidation of CO (COPrOx) is a catalytic reaction targeting the removal of trace amounts of CO from hydrogen-rich gas mixtures. Non-noble metal catalysts, such as Cu and Co, can be equally active to Pt for the reaction; however, their com

Creating active and stable electrodes is an essential step toward efficient and durable electrolyzers. To achieve this goal, understanding what aspects of the electrode structure dictate activity and catalyst dissolution is key. Here, we investigate
