摘要

电力驱动的水分解将水转化为氢气(H2)已被广泛认为是H2生产的有效方法。然而,由于氧化析出反应(OER)动力学缓慢的缺点,其能量转换效率受到极大限制。为了有效解决这个问题,开发了一种新的混合水电解概念,用于节能H2生产。该策略旨在通过利用热力学上有利的有机物氧化反应来取代OER的缓慢动力学。本文系统地总结了这种用于在低电池电压下促进H2释放的水分解系统的最新进展。详细讨论了不同有机物氧化反应与析氢反应的一些显著进展。为了促进混合水电解的发展,还提出了主要的挑战和前景。

Recent advances in hybrid water electrolysis for energy-saving hydrogen production

Recent advances in hybrid water electrolysis for energy-saving hydrogen production

Electricity-driven water splitting to convert water into hydrogen (H2) has been widely regarded as an efficient approach for H2 production. Nevertheless, the energy conversion efficiency of it is greatly limited due to the disadvantage of the sluggish kinetic of oxidation evolution reaction (OER). To effectively address the issue, a novel concept of hybrid water electrolysis has been developed for energy–saving H2 production. This strategy aims to replace the sluggish kinetics of OER by utilizing thermodynamically favorable organics oxidation reaction to replace OER. Herein, recent advances in such water splitting system for boosting H2 evolution under low cell voltage are systematically summarized. Some notable progress of different organics oxidation reactions coupled with hydrogen evolution reaction (HER) are discussed in detail. To facilitate the development of hybrid water electrolysis, the major challenges and perspectives are also proposed.
