Biomass-Derived-Carbon-Supported Spinel Cobalt Molybdate as High-Efficiency Electrocatalyst for Oxygen Evolution Reaction.

ABSTRACT: Ananas comosus leaves were converted to a porous graphitized carbon (GPLC) material via a high-temperature pyrolysis method by employing iron salt as a catalyst. A cobalt molybdate (CoMoO₄)-and-GPLC composite (CoMoO₄/GPLC) was then prepared by engineering CoMoO₄ nanorods in situ, grown on GPLC. N₂ adsorption-desorption isothermal curves and a pore size distribution curve verify that the proposed composite possesses a porous structure and a large specific surface area, which are favorable for charge and reactant transport and the rapid escape of O₂ bubbles. Consequently, the as-synthesized CoMoO₄/GPLC shows low overpotentials of 289 mV and 399 mV to afford the current densities of 10 mA cm^-2 and 100 mA cm
