Preparation of visible-light-active Ag and In-doped ZnS thin film photoelectrodes by reactive magnetron co-sputtering

A facile one pot synthetic approach for C3N4–ZnS composite interfaces as heterojunctions for sunlight-induced multifunctional photocatalytic applications

“…A binding energy difference of 23 eV indicated that Zn ions are in the +2 oxidation state. [50][51][52] An upward shi of 1.93 eV in the binding energy of Zn 2p was due to the interfacial interaction between ZnS and g-C 3 N 4 and formation of N-Zn bonds. 32,53 The peaks at 162.9 and 161.9 showed the S 2p 1/2 and S 2p 3/2 lines of sulphur anions in the lattice of ZnS 23 (Fig.…”

Anti-bacterial activity of indoor-light activated photocatalysts

“…The XPS spectra for the S 2p, Zn2p 1/2 and Zn2p 3/2 locates the peaks at 161.9, 1045.1 and 1022.1 eV respectively, which confirm the material as zinc sulfide. 45,46 It should be noted that the S 2p spectra are composed of 2p 3/2 and 2p 1/2 peaks due to the spin-orbit splitting. Generally, the S2p 3/2 peak at lower binding energy is almost twice the intensity or area of the higher binding energy S 2 p 1/2 peak.…”

A review of non-oxide semiconductors for photoelectrochemical water splitting

“…Atomic doping, forming solid solutions and/or intentionally introducing defects can be used to achieve some useful properties, such as efficient charge separation and transport, modified overpotentials for controlling the redox reaction kinetics and reduced band gap (hence enhanced visible-light absorption). 125,126 These approaches have been applied to various non-oxide PEC photoelectrodes, 48,80,81,[127][128][129][130][131] with some key examples given in Fig. 7.…”
