“…Through photoelectrochemical characterization, it was demonstrated that CdS is less prone to photocorrosion when loaded with either Rh and Ru. 226 In situ photodeposition of metals on CdS in solutions containing sulfide has been studied in detail, 25 revealing that the optimal order of metals to use in photocatalytic H 2 evolution is Rh > Pt > Pd > Ru ≈ Ir > Co ≈ Ni ≈ Fe. Also for Pt, in situ photodeposition resulted in higher photocatalytic activities than use of ex situ obtained Pt/CdS (Figure 16).…”

In this review, for a variety of metals and semiconductors, an attempt is made to generalize observations in the literature on the effect of process conditions applied during photodeposition on (i) particle size distributions, (ii) oxidation states of the metals obtained, and (iii) consequences for photocatalytic activities. Process parameters include presence or absence of (organic) sacrificial agents, applied pH, presence or absence of an air/inert atmosphere, metal precursor type and concentration, and temperature. Most intensively reviewed are studies concerning (i) TiO; (ii) ZnO, focusing on Ag deposition; (iii) WO, with a strong emphasis on the photodeposition of Pt; and (iv) CdS, again with a focus on deposition of Pt. Furthermore, a detailed overview is given of achievements in structure-directed photodeposition, which could ultimately be employed to obtain highly effective photocatalytic materials. Finally, we provide suggestions for improvements in description of the photodeposition methods applied when included in scientific papers.

SUMMARYIn this paper, we are reporting a novel spinel metal oxide photocatalyst, ZnBiGaO 4 for the photocatalytic decomposition of hydrogen sulfide (H 2 S) to generate hydrogen. ZnBiGaO 4 was prepared by two different methods. One is usual solid-state route and another is hydrothermal route, and this is the first time we are reporting ZnBiGaO 4 synthesized by this route. The newly prepared ZnBiGaO 4 was characterized for its crystal structure and microstructure by using XRD and Field Emission Scanning Electron Microscopy (FESEM), respectively. XRD analysis revealed that the structure of ZnBiGaO 4 is cubic spinel structure. The photocatalyst was also characterized by using UV-Visible diffuse reflectance spectroscopy to determine its band gap and was estimated to be 2.8 eV. Our prima facie observations revealed that the formation of single-phase cubic spinel ZnBiGaO 4 with significant photocatalytic activity under visiblelight irradiations for solar hydrogen generation from H 2 S.
