A Heterojunction Cu2O/N–TiO2Photocatalyst for Highly Efficient Visible Light-Driven Hydrogen Production

New BiOXs/TiO 2 heterojunction photocatalyst towards efficient degradation of organic pollutants under visible‐light irradiation

“…The photocatalytic mechanism of BiOXs/TiO 2 should proceed in the P–N junction heterostructure mechanism [33–35]. For the heterojunction, the electrons in the valence band (VB) of the BiOXs can be excited to the conduction band (CB) under visible light illumination, leaving holes (h + ) in the VB.…”

Well-defined Cu2O photocatalysts for solar fuels and chemicals

“…163 The third strategy is the successful establishment of a Zscheme mechanism that efficiently neutralizes the photogenerated hole accumulation in Cu 2 O, thus preventing its photooxidation. [168][169][170][171][172][173] The Liu group developed a hybrid photocatalyst where 2 nm Cu 2 O nanocrystals were uniformly photodeposited on oxygen vacancy containing 101-faceted octahedral TiO 2 nanocrystals (referred to as Cu 2 O/T1-V O ; Fig. 21a and b).…”

Loading of Co3O4 onto Pt-modified nitrogen-doped TiO2 nanocomposites promotes photocatalytic hydrogen production

“…11,12 Elemental doping is an effective way to decrease the semiconductor bandgap. [13][14][15] Nitrogen-doped (N-doped) TiO 2 has widely been used in photocatalytic water splitting, which showed efficient H 2 production under visible light irradiation by narrowing the bandgap energy of TiO 2 . 16,17 At the same time, application of cocatalyst was found to be effective in reducing the recombination of photo generated electron and holes.…”
