In this work, hierarchical hollow BiOBr submicrospheres (HBSMs) were successfully prepared via a facile yet efficient solvothermal strategy. Remarkable effects of solvents upon the crystallinities, morphologies, and microstructures of the BiOBr products were systematically investigated, which revealed that the glycerol/isopropanol volumetric ratio played a significant role in the formation of hollow architecture. Accordingly, the underlying formation mechanism of the hollow submicrospheres was tentatively put forward here. Furthermore, the photocatalytic activities of the resulting HBSMs were evaluated in detail with photocatalytic degradation of the organic methyl orange under visible light irradiation. Encouragingly, the as-obtained HBSMs with striking recyclability demonstrated excellent visible-light-responsive photocatalytic performance, which benefits from their large surface area, effective visible light absorption, and unique hollow feature, highlighting their promising commercial application in waste water treatment.

In2S3/In2O3 composites were fabricated by annealing using metal-organic framework (In-MOF) as precursor, following by sulfurization of In2O3. Structural characterization showed that two kinds of In2S3/In2O3 with different morphologies were obtained by controlling the pH condition during the sulfurization process. Optical characterization results revealed that In2S3/In2O3 heterojunctions display an evidently decreased visible light emission and enhanced visible light absorption compared with that of pure In2O3. The In2S3/In2O3 heterojunction exhibited improved visible-light photocatalytic activities, the optimal composite (pH=2) showed the highest efficiency of 91.14%. The improvement of photocatalytic performance was attributed to the construction of heterojunction.

The catalytic performance of ceria oxide (CeO[Formula: see text] was greatly influenced by the materials’ structure and surface area. In this paper, CeO2 porous nanospheres (PNS) with tunable pore and sphere sizes were synthesized by a solvothermal method using diethylene glycol as reaction media. All the as-synthesized CeO2 PNS presented good adsorption capacity for methyl orange, which makes them potential application in waste water treatment conveniently and economically. The control over the sphere and pore sizes of CeO2 PNS was achieved by regulating the volume of water bubble in the reaction system, which supplied limited room for the assembling of preformed CeO2 small nano-precursors.
