摘要：
Using polystyrene (PS) spheres as a template, three-dimensional ordered macroporous Pt/TiO2-ZrO2 (3DOM Pt/TiO2-ZrO2) composites were prepared by vacuum impregnation combined with photoreduction. The crystal structure, composition, morphology, optical absorption, and surface physicochemical properties of the as-synthetized samples were characterized by X-ray diffraction (XRD), UV-visible diffuse reflectance spectroscopy (UV-vis/DRS), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and N-2 adsorption-desorption analyses. The results showed that the 3DOM Pt/TiO2-ZrO2 composites were mainly composed of anatase TiO2 and tetragonal ZrO2 crystal phases, in which Pt mainly existed as a single species. In addition, the as-synthesized composites had open, three-dimensionally ordered macroporous structures that could enhance their multi-mode photocatalytic degradation performance under UV, visible light, simulated solar light, and microwave-assisted irradiation. Moreover, the 3DOM Pt/TiO2-ZrO2 composites exhibited the best photocatalytic water splitting performance as compared to other systems.
