Rational design and construction of novel hierarchical Au/BPNSs/ZnIn2S4 heterojunction photocatalyst for enhancing photocatalytic H2 production under visible light

Split-type photoelectrochemical immunoassay for sensitive quantification of carcinoembryonic antigen based on target-induced in situ formation of Z-type heterojunction

“…It is noteworthy that the characteristic peaks of Zn 2p in AuNPs/ZnIn 2 S 4 exhibited a positive shift compared to those of pure ZnIn 2 S 4 (relocated to 1023.2 eV and 1046.5 eV), indicative of a reduction in electron cloud density. 41 Conversely, the S 2p and In 3d peaks experienced a negative shift, with the peaks of S 2p shifting to 161.6 eV and 162.8 eV, and the two peaks of In 3d shifting to 445.1 eV and 452.7 eV. This suggests a pronounced interaction between AuNPs and ZnIn 2 S 4 , rather than a mere physical mixture.…”

Interface and Defect Engineering of a Hollow TiO2@ZnIn2S4 Heterojunction for Highly Enhanced CO2 Photoreduction Activity

“…Both the characteristic peaks of TiO 2 and ZIS can be found in the spectra of TiO 2 -ZIS and TiO 2 @ZIS-S. It is noticed that the peak at around 240 cm –1 disappears in the spectra of the composites, which can be attributed to the interaction between TiO 2 and ZIS. − Compared to TiO 2 @ZIS, the peak corresponding to ZIS shifts to a lower wavenumber, while the peak corresponding to TiO 2 shifts to a higher wavenumber for the spectrum of TiO 2 @ZIS-S, which indicates the enhanced interfacial interaction between the two semiconductors …”

ReS2/CdIn2S4–SV Heterojunctions for Photocatalytic Hydrogen Production

“…5,6 Among the various hydrogen production methods, photocatalytic water splitting for hydrogen generation has long been considered one of the most promising technologies to address environmental pollution and energy shortage. 7−10 Metal sulfides, with appropriate band gaps, broad spectral response ranges, and excellent physicochemical properties, such as CdZnS, 11 ZnIn 2 S 4 , 12 and CdIn 2 S 4 , 13 are popular candidates as photocatalysts for water splitting. However, the poor photocorrosion resistance and low efficiency of photogenerated charge carrier separation in metal sulfides, along with the environmental unfriendliness of Cd 2+ , have hampered the catalytic activity and limited research into sulfides.…”
