Internal lattice oxygen sites invert product selectivity in electrocatalytic alkyne hydrogenation over copper catalysts

sites, metallic copper electrocatalyst containing internal lattice oxygen atoms shows an excellent selectivity for selective alkynes hydrogenation toward alkanes (2-methyl-3-butan-2-ol selectivity of 94.9%). This work opens a avenue for steering the selective alkynes hydrogenation, and more importantly, it fills in a gap on the selective electrocatalytic alkynes hydrogenation toward alkanes over copper-based catalysts.
