The metal–support interactions of Cr(OH)3 enhance the performance of supported Au-based benzyl alcohol electrooxidation catalysts†
Abstract
An Au-based heterojunction electrocatalyst supported on Cr(OH)3 was synthesized by a liquid-phase method. The metal–support interactions between Au and Cr(OH)3 play a key role in modulating the microstructure and charge distribution of the Au-based active centers. This synergy significantly enhances the catalytic activity and stability for the electrooxidation of benzyl alcohol.
