摘要
Designing nonprecious but efficient electrocatalysts for the hydrogen evolution reaction (HER) in alkaline solution still remains a significant challenge. Herein, we report the NiMoP nanosheets on hollow Cu3P nanotube arrays on the Cu foam (NiMoP@Cu3P/CF) via solution immersion, hydrothermal reactions and phosphorization. By virtue of its unique core–shell open tubular structure, NiMoP@Cu3P/CF shows large specific surface area and mesoporous, short diffusion paths, which facilitates mass transport and easy accessibility of water, resulting in a superior HER activity in 1.0 M KOH. NiMoP@Cu3P/CF only requires 81 mV and 226 mV of overpotential when the current density is 10 mA cm−2 and 100 mA cm−2 for HER in 1.0 M KOH, respectively, with a low Tafel slope (133.1 mV dec−1) and as well as superior durability. Our work provides a new idea to design a powerful electrocatalyst for HER, which will be highly expected for various practical applications.
