Abstract

The oxygen evolution reaction (OER) under alkaline conditions is a crucial anodic reaction for the electrolysis of water to produce clean hydrogen. To address the resource scarcity and poor stability of traditional noble metal catalysts (such as RuO₂ and IrO₂), metal-organic frameworks (MOFs) and their derivatives employ surface engineering and interface engineering to modify the electronic structure of reactive active sites, optimize the d-band center, and adjust the adsorption energy of oxygen-containing intermediates. Research has demonstrated that the true active sites for the OER rely on metal oxides/hydroxides regenerated from metal sites. This review will establish the connection between surface engineering and interface engineering strategies and the induced reconstruction of MOFs-based electrocatalysts. It will also reveal how to effectively achieve the rational design of pre-catalysts through in-situ characterization techniques. Additionally, performance comparisons will be provided to demonstrate the superiority of these strategies. Based on this, the challenges in the rational design of pre-catalysts for MOFs to achieve more efficient OER catalysts in the future will be proposed.

表面/界面工程及mofs基碱性析氧电催化剂的诱导重建

碱性条件下的析氧反应（OER）是电解水制取清洁氢气的关键阳极反应。为了解决传统贵金属催化剂（如RuO2和IrO2）资源稀缺和稳定性差的问题，金属有机框架（MOFs）及其衍生物利用表面工程和界面工程来修饰活性位点的电子结构，优化d带中心，调整含氧中间体的吸附能。研究表明，OER的真正活性位点依赖于从金属位点再生的金属氧化物/氢氧化物。本文将建立表面工程和界面工程策略与诱导重建mofs基电催化剂之间的联系。揭示了如何通过原位表征技术有效实现预催化剂的合理设计。此外，将提供性能比较来证明这些策略的优越性。在此基础上，提出了mof预催化剂合理设计的挑战，以实现更高效的OER催化剂。
