“…Therefore, how to greatly enhance the activities of photocatalysts is the most important issue. Many researchers have made efforts to promote the activity of CdS particles, such as combining CdS with other semiconductors [11][12][13][14][15][16], forming sulfide solid solution [17][18][19][20], doping metal element [21], as well as preparing various morphological CdS materials [22][23][24][25][26][27][28]. http Recently, significant interest has been devoted to designing semiconductor-carbon composite materials [29], and some studies have proven that carbon can act as sensitizer and transfer electrons to the semiconductors [30].…”

“…CdS with the band gap of around 2.4 eV has demonstrated highly effective absorption of visible light [29]; but its toxicity (since it contains Cd as heavy metal), low photo-stability and high recombination rate of photo-induced charge carriers still are problems in using this photocatalyst. Few layers of WS 2 with the large surface area, high active sites and broadband light absorption is predicted to enhance the CdS photo-activity.…”

a b s t r a c tWe report the well-controlled preparation of WS 2 nanosheets-CdS nanoparticle heterojunction for photoelectrochemical (PEC) water splitting application. The WS 2 nanosheets with an average thickness of $ 5 nm and lateral dimensions of $200 nm were synthesized via liquid phase exfoliation of bulk WS 2 in water/ethanol solution, followed by deposition onto ITO substrate via electrophoretic method. CdS nanoparticles were grown via facile successive ion layer absorption and reaction (SILAR) method. Using these two well-controlled methods, CdS/WS 2 /ITO and WS 2 /CdS/ITO systems were fabricated. The loading of WS 2 nanosheets was controlled by the deposition condition and the heterojunction was optimized for enhanced photoelectrochemical response under simulated sunlight irradiation. The fabricated electrodes were characterized by various analytical techniques as well as PEC response and electrochemical impedance spectroscopy (EIS). Our results showed that the CdS/WS 2 /ITO heterojunction exhibits a stable photo-current density which is 3 times higher than the CdS/ITO electrode. In contrast, photo-current density of the WS 2 /CdS/ITO electrode was lower than that of the bare CdS/ITO, indicating that an appropriate energy level cascade is essential for achieving enhanced PEC response. A charge transfer mechanism was proposed to explain the observed PEC enhancement. This work indicates that the exfoliated WS 2 nanosheet is a promising material for stable photoelectrochemical applications.

View full text Add to dashboard Cite

Cadmium sulfide (CdS)-based photocatalysts have attracted extensive attention owing to their strong visible light absorption, suitable band energy levels, and excellent electronic charge transportation properties. This review focuses on the recent progress related to the design, modification, and construction of CdS-based photocatalysts with excellent photocatalytic H 2 evolution performances. First, the basic concepts and mechanisms of photocatalytic H 2 evolution are briefly introduced. Thereafter, the fundamental properties, important advancements, and bottlenecks of CdS in photocatalytic H 2 generation are presented in detail to provide an overview of the potential of this material. Subsequently, various modification strategies adopted for CdS-based photocatalysts to yield solar H 2 are discussed, among which the effective approaches aim at generating more charge carriers, promoting efficient charge separation, boosting interfacial charge transfer, accelerating charge utilization, and suppressing charge-induced self-photocorrosion. The critical factors governing the performance of the photocatalyst and the feasibility of each modification strategy toward shaping future research directions are comprehensively discussed with examples. Finally, the prospects and challenges encountered in developing nanostructured CdS and CdS-based nanocomposites in photocatalytic H 2 evolution are presented.
