Recent Trends in CO2 Electroreduction over Metal-Organic Framework-Derived Materials: A Comprehensive Review
Abstract
Carbon dioxide reduction through electrochemical energy is an emerging and appealing approach towards CO2 mitigation, and it is a potential technique in which the current and Faradaic efficiencies can be optimized for efficient/effective conversion of CO2 to solar fuel (storable high-density chemical energy). However, the challenge with current state-of-the-art electrocatalytic systems is deeply ingrained in developing efficient, selective, and cost-effective heterogeneous catalysts. Materials derived from metal-organic frameworks (MOFs) are promising electrocatalysts that not only possess porous structures like their parent MOFs but also, they are endowed with improved stability and conductivity required in CO2 reduction reaction (CO2RR). This review surveys the updated strategies to rationally design efficient MOF-based electrocatalysts and MOFs-derived materials for CO2 reduction. Various MOF-derived materials are comprehensively discussed, together with the strategies aimed at improving product selectivity. Active sites and detailed underlying mechanisms for CO2 reduction are discussed to have better insight into future electrocatalyst development. This investigation is expected to allocate the recent advances in CO2RR to inspire new techniques in designing electrocatalysts based on MOF structures with high performance and high stability
