Novel-CdS-nanorod with stacking fault structures: Preparation and properties of visible-light-driven photocatalytic hydrogen production from water

Comparative activity of CdS nanofibers superficially modified by Au, Cu, and Ni nanoparticles as co-catalysts for photocatalytic hydrogen production under visible light

“…The use of CdS semiconductors for photocatalytic applications has attracted much attention since it can be activated in the visible light region; specifically, it has recently been reported for photocatalytic hydrogen production . Different routes of synthesis leading to particular structures and morphologies, such as nanospheres nanorods, nanofibers, nanowires, nanoflowers have been obtained and reported since this semiconductor has the advantage of absorbing throughout the visible region from 300 to 500 nm.…”

Enhanced hydrogen production with photo‐induced phase transformation and cocatalyst loading

“…As shown in Figure 8C,D,E, after the PCHER, the XPS peaks of Cd 3d 5 , Zn 2p, and S 2p shift approximately 0.5 eV in binding energy. 17 Photoluminescence (PL) spectroscopy is highly important to illuminate the charge transfer and electron-hole recombination in the photocatalyst structures ( Figure 9). 17 Photoluminescence (PL) spectroscopy is highly important to illuminate the charge transfer and electron-hole recombination in the photocatalyst structures ( Figure 9).…”

“…6 In recent times, Cd (1 − x) Zn x S photocatalyst having controllable band structure has been drawing great attention with its excellent performance in PC hydrogen production via solar radiation. 17,18 For instance, He et al have reported that CdS nanorods synthesized with the dissolution-recrystallization method displayed more PC performance than CdS prepared by the conventional hydrothermal method, due to the effect of the crystal structure. The previously mentioned novel approaches such as use of different synthetic methods, loading cocatalysts, and doping various metals have been experienced with the aim of improving PC activity of the Cd (1 − x) Zn x S photocatalysts.…”

“…However, the PC activity, photo-stability, and efficiency of this photocatalyst still need to be improved. 17 In addition, it has been reported that the arrangement of the crystal structures can be achieved by light-induced processes. For instance, the decoration of CdS, ZnS, and/or Cd (1 − x) Zn x S nanoparticles with graphene and graphene derivatives such as graphitic carbon nitride (g-C 3 N 4 ), graphene oxide (GO), and reduced graphene oxide (RGO) have appeared as a promising method to overcome these insufficiencies, as a result of the increase in electronic conductivity, surface area, and PC stability.…”

“…On the other hand, a photocatalyst, having a hexagonal crystal structure in addition to the cubic crystal structure, indicates much more hydrogen production activity. 17,18 For instance, He et al have reported that CdS nanorods synthesized with the dissolution-recrystallization method displayed more PC performance than CdS prepared by the conventional hydrothermal method, due to the effect of the crystal structure. 17 In addition, it has been reported that the arrangement of the crystal structures can be achieved by light-induced processes.…”
