Caffeinated- N -Heterocyclic Carbene Ligand at Play in a Molecular H2-Evolving Cobalt Electrocatalyst

In this work, we implemented a proton-responsive caffeine wingtip at the strong sigma-donor N-heterocyclic carbene (NHC) ligand in a new cobalt complex C-2 for the hydrogen evolution reaction (HER) with various proton sources. The NHC ligand is expected to boost the hydricity of the Co–H bond for the reaction with H+...

Experimentally Validated Cobalt Phosphinothiolate Hydride Intermediate Governs the Selectivity Switch between Formate and Syngas in CO2 Reduction

Controlling product selectivity in homogeneous electrocatalytic CO2 reduction remains a significant challenge, often requiring complicated catalyst redesigning. Herein, we identify and validate a cobalt-hydride intermediate that governs the selectivity switch for CO2 reduction to either formate or synthesis gas (syng...
