Abstract

Cerium oxide (CeO₂) photo/electrocatalysts for energy storage and environmental applications have attracted considerable interest because of stable crystal structure, low toxicity/cost, superior chemical stability, stable redox (Ce³⁺/Ce⁴⁺) pairs, abundant oxygen defects, and capablility for intense interaction with other materials. However, the wide bandgap and poor conductivity lower the CeO₂ photo/electrocatalytic and energy storage performances. To overcome these limitations, various modification strategies (tuning morphology, doping or loading of metal nanoparticles, and heterostructures) have been applied for the improvement of photocatalytic (removal of organic contaminants from water/wastewater and H₂ production and CO₂ reduction reactions) efficiency, electrocatalytic (hydrogen/oxygen evolution reactions and CO₂ reduction reactions), and energy storage performances (supercapacitor) of CeO₂-based materials. Herein, the recent progress of CeO₂-based materials for electro(photo)catalysis and energy storage applications has been discussed. The challenges and possible direction of CeO₂-based materials for electro(photo)catalysis and energy storage applications have been emphasized. Furthermore, this comprehensive review is expected to advance the design of CeO₂-based materials and their applications in electro(photo)catalysis and energy.

基于氧化铈的纳米结构在能源和环境中的应用研究进展

氧化铈（CeO2）光/电催化剂由于其稳定的晶体结构、低毒性/低成本、优异的化学稳定性、稳定的氧化还原（Ce3+/Ce4+）对、丰富的氧缺陷以及与其他材料强烈相互作用的能力而引起了人们的广泛关注。然而，较宽的带隙和较差的导电性降低了CeO2的光电催化和储能性能。为了克服这些限制，各种修饰策略（调整形态、掺杂或负载金属纳米颗粒和异质结构）已被应用于改善ceo2基材料的光催化（去除水/废水中的有机污染物和H2生成和CO2还原反应）效率、电催化（氢/氧释放反应和CO2还原反应）和储能性能（超级电容器）。本文综述了近年来ceo2基材料在电（光）催化和储能方面的研究进展。强调了ceo2基材料在电（光）催化和储能应用中的挑战和可能的方向。此外，本文的综合综述有望推动ceo2基材料的设计及其在电（光）催化和能源方面的应用。
