Nickel‐Based Complexes Doped Silver Nanocomposites for Efficient Electrocarboxylation of Allylic Chloride

Abstract Various nickel‐based catalyst‐doped silver nanomaterials ([Ni]@Ag) were synthesized by chemical reduction in an aqueous phase. The surface topography and composition of the catalyst were verified using field‐emission scanning electron microscopy (FE‐SEM) and energy‐dispersive X‐ray spectroscopy (EDX). In the electrocarboxylation of allyl chloride with CO 2 , [Ni]@Ag served as the catalytic cathode, whereas Mg functioned as the sacrificial anode. Under normal CO 2 pressure at 0 °C, the yield of vinylacetic acid reached 95%. Notably, [Ni]@Ag demonstrated high reusability for CO 2 allylation, with no loss in catalytic efficiency. A preliminary reaction mechanism was also proposed.
