Interfacial modification and band modulation for dramatically boosted photocatalytic hydrogen evolution

Ferroelectric field enhanced tribocatalytic hydrogen production and RhB dye degradation by tungsten bronze ferroelectrics

“…57 The energy band structure of nano-TiO 2 also meets the requirements for hydrogen production. 58 But with a similar bandgap, the hydrogen production efficiency of nano-TiO 2 is significantly lower than that of BSNT. Based on this, it can be inferred that ferroelectric built-in electrical fields have the potential to enhance tribocatalytic hydrogen production and dye degradation.…”

Activating the (101) facets of Cu2WS4 in the CdS/Cu2WS4 S-scheme heterojunction to enhance the photocatalytic hydrogen evolution activity

“…The interaction between the CdS and the Cu 2 WS 4 interface effectively improves the light capture ability of the catalyst under ultraviolet and visible light. 29 The sharp absorption peak of CCS10 at 610 nm is formed by the energy band transition of electrons from the valence band to the conduction band. According to the Tauc diagram, the bandgaps of Cu 2 WS 4 and CdS are estimated to be 2.13 eV and 2.15 eV, respectively (Fig.…”

Construction of Ag-TiO2 Hierarchical Micro-/Nanostructures on a Ti Plate for Photocatalysts via Femtosecond Laser Hybrid Technology

“…An optimal photocatalyst should possess a wide light absorption range, coupled with the efficient generation and transfer of photogenerated carriers. Currently, the two promising approaches for extending TiO 2 's absorption capacity into the visible region are band gap modification [10][11][12] and the creation of gradient microsurfaces [13][14][15]. The band gap of TiO 2 can be effectively broadened to the visible spectrum by doping with metals (such as Au, Ag, Fe, and Pd) [16][17][18][19] and non-metals (such as N and C) [20,21] to introduce intermediate energy levels.…”
