In recent decades, with the rapid development of the inorganic synthesis and the increasing discharge of pollutants in the process of industrialization, hollow-structured metal oxides (HSMOs) have taken on a striking role in the field of environmental catalysis. This is all due to their unique structural characteristics compared to solid nanoparticles, such as high loading capacity, superior pore permeability, high specific surface area, abundant inner void space, and low density. Although the HSMOs with different morphologies have been reviewed and prospected in the aspect of synthesis strategies and potential applications, there has been no systematic review focusing on the structures and compositions design of HSMOs in the field of environmental catalysis so far. Therefore, this review will mainly focus on the component dependence and controllable structure of HSMOs in the catalytic elimination of different environmental pollutants, including the automobile and stationary source emissions, volatile organic compounds, greenhouse gases, ozone-depleting substances, and other potential pollutants. Moreover, we comprehensively reviewed the applications of the catalysts with hollow structure that are mainly composed of metal oxides such as CeO, MnO, CuO, CoO, ZrO, ZnO, AlO, InO, NiO, and FeO in automobile and stationary source emission control, volatile organic compounds emission control, and the conversion of greenhouse gases and ozone-depleting substances. The structure-activity relationship is also briefly discussed. Finally, further challenges and development trends of HSMO catalysts in environmental catalysis are also prospected.
近几十年来，随着无机合成的快速发展以及工业化进程中污染物排放的增加，中空结构金属氧化物（HSMOs）在环境催化领域发挥了显著作用。这完全归因于它们与固体纳米颗粒相比具有独特的结构特征，如高负载能力、优异的孔隙渗透性、高比表面积、丰富的内部空隙空间和低密度。尽管不同形貌的HSMOs在合成策略和潜在应用方面已有综述和展望，但迄今为止，在环境催化领域尚未有针对HSMOs结构和组成设计的系统综述。因此，本综述将主要聚焦于HSMOs在催化消除不同环境污染物方面的成分依赖性和可控结构，这些污染物包括汽车和固定源排放物、挥发性有机化合物、温室气体、消耗臭氧层物质以及其他潜在污染物。此外，我们全面综述了主要由CeO、MnO、CuO、CoO、ZrO、ZnO、AlO、InO、NiO和FeO等金属氧化物组成的中空结构催化剂在汽车和固定源排放控制、挥发性有机化合物排放控制以及温室气体和消耗臭氧层物质转化方面的应用。还简要讨论了结构 - 活性关系。最后，展望了HSMO催化剂在环境催化中的进一步挑战和发展趋势。
