Summary: Anatase TiO2 hierarchically structured microspheres with co-exposed {001}/{101} facets were prepared by a facile one-pot hydrothermal method. The morphology and crystallization of the microspheres were systematically investigated under different reaction temperatures, and it was found that the microspheres exhibited better properties at a temperature of 160°C. Modification of the microspheres with different noble metals (Au, Ag, Cu, Pt, Pd) resulted in significantly enhanced photocatalytic activities, with the Pt-modified sample (TPt) showing the highest activity in the degradation of tetracycline hydrochloride and hydrogen production.

Summary: Single crystalline anatase TiO2 microspheres with {001}/{101} facets were synthesized via a facile one-pot hydrothermal method using NaF as a morphology controlling agent. The effects of NaF amount on morphology and photocatalytic activity were systematically investigated. Results showed that microspheres with improved morphology were obtained at a NaF concentration of 0.1 mol/L. Furthermore, the crystal structure and morphology were found to play significant roles in the photocatalytic activity, with TiO2 microspheres achieving a degradation efficiency of 76.4% for Tetracycline hydrochloride within 2 hours. A growth mechanism involving F ion modified Ostwald ripening and oriented attachment was proposed based on the investigation of the growth process.

Summary: A cellulose-based photocatalytic membrane was fabricated by growing NH2-MIL-125 nanoparticles onto the surfaces of ultrathin titania gel-coated cellulose nanofibres. The composite membranes maintained the hierarchical network structures of cellulose and showed enhanced photocatalytic performances due to the effective heterostructure formation between NH2-MIL-125 particles and TiO2 layers.

Summary: A hierarchical structure composed of Pt@Co3O4/TiO2 (CTP) ternary nanocomposite was synthesized and demonstrated for its enhanced and durable production of hydrogen from glycerol under simulated solar light irradiation. The optimized composition showed a hydrogen production rate of 19.2 mmol h(-1) g(cat)(-1). The heterojunction formed in the ternary system remarkably enhanced the visible light absorption properties and charge separation in CTP, leading to improved and durable photocatalytic efficiency towards hydrogen production.

Summary: Surface amorphization via a crystalline/amorphous core-shell structure is an effective approach for constructing a high-efficiency photocatalyst. The innovative crystalline/amorphous stacking structure of SnO2 microspheres significantly improves photocatalytic NO removal under visible light irradiation. This structure enhances charge separation efficiency and inhibits surface absorption competition, leading to the generation of more active oxygen species for NO oxidation.

Summary: A novel cellulose carbon aerogel@Na2Ti3O7@Cu2O (CA@Na2Ti3O7@Cu2O) nanocomposite was prepared and demonstrated excellent adsorption capacity for heavy metal ions and photocatalytic activity for methylene blue (MB) removal. The cationic intercalation structure of Na2Ti3O7 nanosheets contributed to the high adsorption capacity, while the Cu2O nanoparticles exhibited outstanding photocatalytic activity with a removal rate of up to 99%. Moreover, the CA@Na2Ti3O7@Cu2O nanocomposites could be easily regenerated and reused, providing a new solution for wastewater treatment.
