Fig. 1: Enhancing electrocatalytic acetone hydrogenation performance through morphology and crystal phase regulation strategy.

a A high acetone conversion and isopropanol production rate due to strong adsorption of acetone and rapid desorption of isopropanol on hcp Ni NSs. b A low acetone conversion caused by weak adsorption of acetone and slow desorption of isopropanol on fcc Ni NPs.
