摘要

近年来，通过尿素氧化反应(UOR)和析氢反应(HER)生产氢气(H2)因其更加环保和节能而受到广泛关注。本文提出了一种水活化方法，在不使用粘合剂或加压或加热步骤的情况下，在NiMo泡沫上原位生长NiMo LDH纳米片阵列。所得的NiMo泡沫电极在UOR和HER中都表现出优异的催化活性和耐久性。这项工作为设计高效、可持续的尿素有机氧化制氢电极提供了新的观点。

Water activating fresh NiMo foam for enhanced urea electrolysis†

Recently, production of hydrogen (H₂) through the urea oxidation reaction (UOR) and hydrogen evolution reaction (HER) has acquired great attention because it is more environmentally friendly and energy-saving. Herein, an approach of water activation was developed for in situ growth of NiMo LDH nanosheet arrays on NiMo foam without using any binder or pressurizing or heating steps. The obtained NiMo foam electrodes showed exceptional catalytic activity and durability for both the UOR and HER. This work offers a new standpoint on designing electrodes with high activation for efficient and sustainable hydrogen production coupled with urea organic oxidation.
