Ligand-Controlled Engineering of Cu–H Active Sites on Cu25 Hydride Nanoclusters for Efficient CO2 Electroreduction

Atomic-level control of catalytic selectivity is critical to nanocatalyst design. Here, we report two structurally defined Cu hydride nanoclusters, [Cu25H22(p-FPh3P)12]+ and [Cu25H10(2,4-F2PhS)18]3−, with distinct hydride contents that govern active-site exposure...
