DataSheet1_One-Step Synthesis of Bifunctional Nickel Phosphide Nanowires as Electrocatalysts for Hydrogen and Oxygen Evolution Reactions.pdf

The Ni2P nanowires were simply synthesized via a rapid one-step hydrothermal approach, in which deionized water, red phosphorus, nickel acetate, and hexadecyl trimethyl ammonium bromide were used as the solvent, phosphor and nickel sources, and active agent, respectively. The as-synthesized Ni2P nanowire clusters were composed of uniform nanowires with length of about 10 μm and diameter of about 40 nm. The Ni2P nanowires exhibited enhanced electrocatalytic activity for both hydrogen evolution reaction and oxygen evolution reaction This work provides good guidance for the rational design of nickel phosphides with unique nanostructures for highly efficient overall water splitting.

本研究通过快速一步水热法简便合成了二磷化镍（Ni₂P）纳米线，反应体系以去离子水为溶剂、红磷为磷源、乙酸镍为镍源、十六烷基三甲基溴化铵为活性剂。所合成的二磷化镍纳米线团簇由长度约10 μm、直径约40 nm的均匀纳米线组装而成。该二磷化镍纳米线对析氢反应（Hydrogen Evolution Reaction）与析氧反应（Oxygen Evolution Reaction）均展现出增强的电催化活性。本研究为合理设计具备独特纳米结构、可用于高效全解水的磷化镍材料提供了有益指导。
