Study on Modified Nickel Foam as A High-efficiency Electrocatalyst for Water Cracking

水裂解是一种先进的能量转化技术,由析氧反应(OER)和析氢反应(HER)两个半反应组成。电解水制取高纯氢技术是目前能源开发的一个重要领域。电解水的关键技术是制备高效催化、稳定耐用的电极,用于降低电解水析氢反应和析氧反应的过电位。然而,催化材料的选择是研究电解水制取氢气和氧气的一个重要方向。本文主要综述了利用三维泡沫镍基制造纳米结构材料用于水裂解的最新进展以及局限性和前景。

Water cracking is an advanced energy conversion technology,which consists of two half reactions:oxygen evolution(OER)and hydrogen evolution(HER).The technology of electrolyzing water to produce high purity hydrogen is an important field of energy development at present.The key technology of water electrolysis is to prepare highly efficient catalytic,stable and durable electrodes for reducing the overpotential of hydrogen evolution and oxygen evolution reactions.However,the selection of catalytic materials is an important direction in the study of hydrogen and oxygen production from water electrolysis.The latest progress,limitations and prospects of nanostructured materials manufactured by three-dimensional nickel foam for water cracking were reviewed.
