ABSTRACT
Considering the high costs of producing catalysts, designing a bifunctional catalyst is one of the favorable ways through which the best result can be achieved with less effort. Herein, we use a one-step calcination method to obtain a bifunctional catalyst Ni2P/NF for the simultaneous oxidation of benzyl alcohol (BA) and reduction of water. A series of electrochemical tests have shown that this catalyst has a low catalytic voltage, long-term stability and high conversion rates. The theoretical calculation unveils the essential reason for its excellent activity. The synergistic effect of Ni and P optimizes the adsorption and desorption energy of the intermediate species, thus reducing the energy barrier of the rate-determining step during BA electrooxidation. Thus, this work has laid the foundation for designing a highly efficient bifunctional electrocatalyst for BA oxidation and the hydrogen revolution.
