太阳能驱动的光电化学(PEC)将二氧化碳(CO2)转化为有价值的化学品,结合了电化学和电催化的优点,是建立碳中和社会和利用太阳能的一种有前途的方法。掺杂有金属和/或非金属的光电极材料已经显示出实现高CO2还原效率的前景。金属或非金属掺杂需要将异质元素引入到半导体中,从而通过添加缺陷态来修改半导体的能带电势。这种改变可以改善催化的电荷转移动力学。此外,掺杂有助于产生活性CO2吸附,为CO2分子提供锚定位点,并可提高产品选择性。这篇综述旨在通过PEC过程提供用于将CO2转化为燃料的元素掺杂光电极的简要总结。讨论了影响PEC CO2还原性能的几个关键因素,包括反应物与催化剂的相互作用、反应条件以及光电极的影响。此外,各种PEC CO2减排系统进行了讨论,特别侧重于提高CO2减排的效率。最后,总结了进一步发展PEC二氧化碳减排的关键考虑因素。
Solar‐driven photoelectrochemical (PEC) carbon dioxide (CO2) conversion to valuable chemicals, combining the advantages of photocatalysis and electrocatalysis, represents a promising approach toward establishing a carbon‐neutral society and harnessing solar energy. Photoelectrode materials doped with metals and/or nonmetals have shown promise in achieving high CO2reduction efficiency. Metal or nonmetal doping entails introducing a heteroelement into the semiconductor, thereby modifying the band potentials of the semiconductor through the addition of a defective state. This alteration may improve the charge transfer kinetics of the catalysis. Furthermore, doping aids in creating active CO2adsorption offers anchoring sites for CO2molecules and can promote product selectivity. This review aims to provide a concise summary of elemental‐doped photoelectrodes for converting CO2into fuels through PEC processes. Several key factors affecting the performance of PEC CO2reduction are discussed, including the interaction of reactants with catalysts, reaction conditions, and the impact of the photoelectrode. Moreover, various PEC CO2reduction systems are discussed, with a specific focus on enhancing the efficiency of CO2reduction. Finally, a summary of key considering aspects for further development of the PEC CO2reduction is provided.
