The collaborative mechanism of surface S-vacancies and piezoelectric polarization for boosting CdS photoelectrochemical performance

Sulfate-Functionalized Core–Shell ZnO/CdS/Ag2S Nanorod Arrays with Dual-Charge-Transfer Channels for Enhanced Photoelectrochemical Performance

“…The eight purple-marked diffraction peaks belong to the wurtzite ZnO (JCPDS: 01-075-1526) . The three green-marked diffraction peaks located at 25.06, 28.59, and 43.92° are matched with the (110), (100), and (101) planes of CdS (JCPDS: 00-002-0563), respectively. Apart from the above-mentioned diffraction peaks, the others are ascribed to the FTO substrate (Figure S2a).…”

Recent advances in solution assisted synthesis of transition metal chalcogenides for photo-electrocatalytic hydrogen evolution

“…It is proved by computational and experimental studies that the catalytic activity of transition metal chalcogenides, particularly 2H-phase 2D-transition metals, is due to active edge sites, while the basal plane contributing the bulk of the material is catalytically inactive, which drastically limits its application in catalytic reactions. 24,[154][155][156][157][158][159][160][161] Among the several methods available, phase transition and defect generation are the most promising approaches to activate the basal plane. The beneficial role of defect generation for hydrogen evolution in MoS 2 was first identified by Xie's group.…”

Visible Light Photoanode Material for Photoelectrochemical Water Splitting: A Review of Bismuth Vanadate

“…In recent years, how to regulate the defect of materials so that materials show better performance in the PEC process is the focus of many researchers. Numerous studies have demonstrated that the introduction of defects, especially point defects, has a positive impact on the performance of metal-based PEC catalytic materials, including BiVO 4 , CdS, WO 3 , CuO, BiOCl, etc. − …”
