TiO2hollow microspheres were synthesized by a facile solvothermal method. The prepared samples were characterized by the XRD, SEM, TEM, BET and UV-vis. The results showed that the TiO2hollow microspheres offered an enhanced photocatalytic activity due to the multiple reflections of the UV light within the inner hollow structure.

A novel phthalocyanine-sensitized hollow ZnO spheres as an efficient visiblie-light photocatalyst had been prepared successfully. Firstly, a unique hollow ZnO microsphere had been prepared by a facile solvothermal method followed by calcination. Secondly, zinc-tetracarboxyl-phthalocyanine (Pc) impregnated onto the surface of hollow ZnO microsphere. The obtained photocatalyst Pc/ZnO was characterized by XRD, SEM and EDS. The hollow Pc/ZnO hierarchical nanostructure improved the electron-hole separation more effectively and Pc loaded on the surface of ZnO microsphere to enhance photocatalytic activity under visible light. In our photocatalytic experiments, the hollow Pc/ZnO microsphere showed excellent photocatalytic performance under visible light for the removal of Rhodamine B (RhB). As a result, our work provided an effective and green photocatalyst for water treatment.

Novel 3D flower-like bismuth oxyiodide (BiOI) nanomaterials were obtained via a facile solvothermal method using bismuth nitrate (Bi(NO3)3) and potassium iodide (KI) as precursors and diethylene glycol as the capping reagent. The morphology of the BiOI nanoarchitecture strongly depends on the experimental conditions such as the presence of diethylene glycol and hydrothermal time. The photocatalytic property of the BiOI nanostructures by monitoring the degradation of rhodamine B (RhB) and methyl orange (MO) mixed dyes was studied under visible light illumination, which has not been reported previously. The degradation of single cationic RhB dye is faster when compared with that of anionic MO dye. This result is due to the surface negative charges on the BiOI nanoflowers that display good selectivity towards positive RhB dye organic groups owing to electrostatic attraction.

In this paper, the biomass carbon quantum dots (CQDs) modified flower-like BiOI (CQDs/BiOI) composite photocatalyst was synthesized by a facile solvothermal method. Compared with the pristine BiOI, the biomass CQDs/BiOI exhibited outstanding photocatalytic activity for degradation of the typical methylene blue (MB) under visible light irradiation since the biomass CQDs could act as electron acceptors to effectively facilitate the separation efficiency of photon-generated carriers and prolong their lifetime. Furthermore, the mechanism detection experiment showed that the [Formula: see text] and H[Formula: see text] were major activity species, and the photocatalytic electron transfer mechanism was further investigated. This work provided a new insight into biomass CQDs effects and took an important step toward the development of improving Bi-based semiconductor photocatalyst activity.

Zn0.4Cd0.6S/TiO2/Reduced graphene oxide (Zn0.4Cd0.6S/TiO2/RGO) nano-photocatalyst was synthesized by a facile solvothermal method. During the reaction, TiO2 and Zn0.8Cd0.2S nanoparticles were evenly dispersed across the surface of RGO, which enhanced response to visible light. The photocatalytic activity of as-synthesized Zn0.4Cd0.6S/TiO2/RGO nanomaterial was studied by means of degrading methylene blue (MB) through the irradiation of visible light. Compared with other nanomaterials, the Zn0.4Cd0.6S/TiO2/ RGO nanomaterials showed the highest photocatalytic degradation efficiency (96%) and high stability, which was 5.4 times of photodegradation efficiency of pure TiO2.
