A Trifunctional Ni-P/Fe-P Collaborated Electrocatalyst Enables Self-Powered Energy Systems.

ABSTRACT: Recently, extensive research efforts have been devoted to drive electrocatalytic water-splitting for hydrogen generation by electricity or solar cells. However, electricity from power grid and the intermittent property of sunlight inevitably brings about environmental pollution and energy loss. Thus, a novelty energy system for simultaneous generating H₂ from solar energy and overcoming the intermittence of sunlight is highly desirable. Herein, a self-powered energy system with solar energy as the sole input energy is successfully assembled by integrated Zn-air batteries with stable output voltage, solar cells, and water splitting electrolyzer to efficient H₂ production. Specially, the Zn-air batteries are charged by the solar cell to store intermitted solar energy as
