Robust direct Z-scheme exciton transfer dynamics by architecting 3D BiOI MF-supported non-stoichiometric Cu0.75In0.25S NC nanocomposite for co-catalyst-free photocatalytic hydrogen evolution

“…8 Additionally, the Z-scheme photocatalyst displays robust photoredox capability due to the following features: (i) availability of useful photoinduced charge carriers with high redox potential; (ii) reductive and oxidative centers are separated; (iii) two semiconductors are used without any mediator; and (iv) increased photon absorption range. 9,10 Additionally, our group has made tremendous advancements and has reported several Z-scheme oriented systems like BiVO 4 /CdS/MgAl-LDH, {040/110}-BiVO 4 @Ag@CoAl-LDH, BiOI-CeO 2 , MoS 2 /NiFe-LDH, NiFe-LDH/N-rGO/g-C 3 N 4 , Cu-MoO 3 /g-C 3 N 4 , BN/BCN, HPW@UiO-66, WO 3Àx /Ag/ZnCr-LDH and TiO 2 /BCN towards energy production and pollutant detoxication. 5,6,[10][11][12][13][14] In the past decades, bismuth oxyhalides classied as V-VI-VII group ternary oxides with tetragonal matlockite geometry have gathered huge attention as semiconductor photocatalysts due to their non-toxic nature, favorable economy, easy fabrication, excellent conductivity and broad light absorption properties.…”

In situ Irradiated XPS Investigation on S‐Scheme TiO2@ZnIn2S4 Photocatalyst for Efficient Photocatalytic CO2 Reduction

“…And it has been used for various photocatalytic applications including hydrogen production, CO 2 reduction, and organic degradation. [45][46][47][48][49][50][51] Unfortunately, pristine ZnIn 2 S 4 photocatalyst shows low photocatalytic efficiency owing to the fast recombination of photogenerated charge carriers. [45][46][47][48][49] Considering the suitable match of band gap of ZnIn 2 S 4 and TiO 2 for S-scheme heterojunction, [27,52] we construct the hollow TiO 2 @ZnIn 2 S 4 core-shell structure.…”

In Situ Construction of Direct Z‐Scheme CsxWO3/CsPbBr3 Heterojunctions via Cosharing Cs Atom

“…For instance, Mishra and coworkers developed a facile reflex method to prepare Bi 2 S 3 /β‐Bi 2 O 3 /ZnIn 2 S 4 ternary nanocomposites via sharing Bi atom, which exhibited effective Z‐scheme charge transfer and enhanced photocatalytic performances for multimodal applications of wastewater treatment, hydrogen production, and microbial disinfection. [ 17 ] Sun and coworkers synthesized a mesoporous In 2 O 3− x /In 2 S 3 heterostructure via using oxygen plasma to in situ oxide In 2 S 3 atomic layers, which showed a significantly enhanced performance in photoelectrochemical water splitting.
