摘要:

廉价电催化剂是电解水制氢的研究热点之一。目前,针对钢基电解水制氢催化剂的系统性分析尚不充分。本文归纳了近40年来不锈钢、低碳钢等钢基电解水制氢电催化剂的研究进展,分别对其作为析氧电催化剂、析氢电催化剂、析氢-析氧双功能电催化剂进行了介绍和剖析。通过对钢基电催化剂的不同制备方法、制备流程以及电催化反应条件等的分析,指出了其作为阳极析氧以及阴极析氢的活性、稳定性和耐受性的影响因素,归纳了不同制备方法存在的问题和电催化剂的使用条件。分析发现,析氧电催化剂和析氢析氧双功能电催化剂主要以不锈钢为基体制备而成,而析氢电催化剂则主要以低碳钢为基体制备而成。在此基础上,本文提出了后期研究钢基电催化剂的重点、方向以及改进方式,为制备高性能电解水制氢电催化剂及其工业化应用提供参考。

Abstract:

Inexpensive electrocatalysts are one of the research hotspots in the production of hydrogen from water electrolysis. There are few systematic summaries the steel-based electrocatalyst for water splitting. This review summarized the research status of steel-based electrocatalysts (stainless steel, low-carbon steel and other steels) in the past 40 years, and introduced them as oxygen evolution electrocatalysts, hydrogen evolution electrocatalysts, dual-function electrocatalysts. In this paper, the different preparation methods, fabrication processes and electrocatalytic reaction conditions were analysized. Meanwhile, the influencing factors of the activity, stability and tolerance of oxygen evolution at anode and hydrogen evolution at cathode were summarized. It was found that the oxygen evolution electrocatalyst and the hydrogen-oxygen evolution bifunctional electrocatalyst were mainly prepared with stainless steel as the matrix, while the hydrogen evolution electrocatalyst was prepared with the low carbon steelas the matrix. Furthermore, advantages and disadvantages of fabrication methods and further research focus were discussed. The in-depth understanding provides the guidance for the design of the high-performance water splitting electrocatalysts for industrial applications.
