Controllable hydrothermal synthesis, optical and photocatalytic properties of TiO2 nanostructures

Preparation and characterization of TiO 2 -based nanosheets for photocatalytic degradation of acetylsalicylic acid: Influence of calcination temperature

“…Usually, the hydrothermal temperature, the reaction time, the concentration of the reactants and pH of the solution [30,31] were studied. However, the results showed that the subsequent calcination treatment had a crucial influence on the surface morphology, crystallite size, crystallinity, phase composition and photocatalytic properties of TiO 2 -based nanomaterials [32,33].…”

Femtosecond Laser Fabrication of Anatase TiO2 Micro-nanostructures with Chemical Oxidation and Annealing

“…aqueous purification, micro/nanostructured TiO 2 is mostly fabricated in the form of suspended powder, which is difficult to recycle from aqueous solution after photocatalytic reactions and will cause secondary pollution. The most common approach to solve this problem is to fabricate self-supported TiO 2 micro-nanostructures by coating TiO 2 particles onto a conductive substrate to form a film or membrane, as is the case with fabricating photocatalytic purifiers at present 12, 13 . However, the coated TiO 2 particles are prone to stripping from the substrate, leading to compromised photocatalytic properties.…”

Enhanced photoelectronic properties of single crystal TiO2 nanosheet array films by selective deposition of CdS nanoparticles on their {101} facets

“…21-1272). Unlike the conventional method for preparing TiO 2 , 29,30 the (004) diffraction peak here is significantly enhanced, indicating the exposure of a large percentage of {001} facets. 28 Compared with the obvious anatase phase, the diffraction peaks of CdS were not easily observed, implying its low content and the small size of CdS species.…”
