Summary: In this study, a novel type of hollow hierarchical porous TiO2/Ag composite microsphere with tunable microstructure was successfully prepared. Compared with hollow hierarchical porous TiO2 microspheres, the composite microspheres showed a shift in excitation wavelength towards visible light direction, improved response range and light utilization rate. The optimal addition amount of Ti and Ag resulted in specific surface area of 177 m2/g, pore volume of 0.37 cm3/g, and primary and secondary pore sizes of 4.04 nm and 7.74 nm, respectively. They exhibited the highest photocatalytic activity towards 365 nm and 395 nm ultraviolet light, with degradation rates of methyl orange solution reaching 96.84% and 98.65%, respectively. Their excellent performance was attributed to the unique combination of hierarchical pores and hollow structures, as well as the synergistic effect of Ag and TiO2.

Summary: C/Ti3C2/(001)TiO2 hollow microspheres were prepared via the combination of the template method, self-assembly, and hydrothermal method. The microspheres exhibited anatase TiO2 nanosheets with oxygen vacancies and exposed active (001) facets on the spherical surface. C/Ti3C2/(001)TiO2-HMs showed higher TC removal efficiency (92.3%) compared to TiO2 (28.4%) and (001)TiO2/Ti3C2 (49.5%) due to the presence of oxygen vacancies, extended light absorption range, and promotion of electron-hole pair generation. The composite structure of C/Ti3C2/(001)TiO2 could suppress electron-hole pair recombination and prolong their lifetime, making it a potential choice for wastewater treatment.

Summary: In this study, visible light responsive well-dispersed Bi-0/OVs-BiOCOOH hollow microspheres were prepared through a solvothermal method using colloidal carbon nanospheres (CSs) as sacrificial templates and reductants. The CSs played multiple roles in the synthesis of hollow Bi-0/OVs-BiOCOOH microspheres, and the hollow structure may have been caused by the redox reaction between CSs and BiO+ during synthesis. The SPR effect of Bi-0 enhanced the photocatalytic performance by promoting visible light absorption. Additionally, the introduction of oxygen vacancies (OVs) on the surface of BiOCOOH established defective energy levels, improving the photocatalytic capability by accelerating the separation of photogenerated carriers. The degradation performance of Bi-0/OVs-BiOCOOH for decontamination of tetracycline (TC) was 4.86 times that of BiOCOOH. Based on the observations, the photocatalytic mechanism of Bi-0/OVs-BiOCOOH for TC photodegradation was elaborated.
