“…However, compared to the pristine CdS, the contribution of nonradiative recombination was significantly improved on CA-10 samples to at least 10% (according to the contribution of Table S3), indicating that AgBr was effective in promoting charge transfer/separation than on pristine CdS in the decay process. A similar decay process had been observed in Wang’s work …”

“…35 After the introduction of AgBr, the peak of Cd 3d shifted about 0.5 eV toward higher energy than pure CdS, indicating strong interactions between these two species. 35,43 A similar phenomenon could be found in Figure S3b. 36 It is well known that the change in binding energy in the XPS energy spectrum reflected the change in electron concentration.…”

We designed and fabricated an AgBr/CdS S-scheme heterojunction with Ag–S bonds. It was found that the formed Ag–S bond served as a bridge to transfer photoinduced electrons from CdS to AgBr. The as-prepared AgBr/CdS materials showed remarkably enhanced performance and good stability for photocatalytic hydrogen evolution using triethanolamine (TEOA) as the sacrificial agent. Under visible light illumination, the 10% AgBr/CdS sample exhibited optimal activity (5406 μmol h–1 g–1) among all samples, which was 85 times higher than that of the pristine CdS (64 μmol h–1 g–1). Because of the formation of the AgBr/CdS S-scheme heterojunction and the rapid electron-transfer channel provided by Ag–S bonds, high charge separation and utilization efficiency were achieved, which contributed to its superior performance.

“…Moreover, we coupled waste toner powder with a Ni species, given the positive effect of Ni-based cocatalysts on enhancing the activity of photocatalysts for the HER reaction. 11–15 Here, it is found that, when activated by the Ni species, the hydrogen evolution rate of the pristine waste toner could achieve 944 μmol g −1 in 2 h, which was about 62 times higher than that of the pristine waste toner. The role of the Ni species in activating the waste toner is discussed in detail in this work.…”

“…However, it has been proved that CdS always suffer from fast recombination of photogenerated charge carriers and severe photocorrosion, which seriously block the improvement of the photocatalytic efficiency of CdS photocatalysts [ 14 , 15 ]. In order to improve the light utilization and photocatalytic efficiency of CdS, commonly used solutions include element doping [ 16 , 17 ], cocatalyst loading [ 18 , 19 , 20 , 21 ] and the construction of heterojunctions [ 19 , 22 , 23 , 24 ]. Especially, elemental phosphorus (P) has been introduced into the CdS lattice to reduce the free energy of H 2 adsorption and enhance its visible light absorption and corrosion resistance [ 24 , 25 , 26 ].…”

Formic acid is an appealing hydrogen storage material. In order to rapidly produce hydrogen from formic acid under relatively mild conditions, high-efficiency and stable photocatalytic systems are of great significance to prompt hydrogen (H2) evolution from formic acid. In this paper, an efficient and stable photocatalytic system (CdS/P/MoS2) for H2 production from formic acid is successfully constructed by elemental P doping of CdS nanorods combining with in situ photodeposition of MoS2. In this system, P doping reduces the band gap of CdS for enhanced light absorption, as well as promoting the separation of photogenerated charge carriers. More importantly, MoS2 nanoparticles decorated on P-doped CdS nanorods can play as noble-metal-free cocatalysts, which increase the light adsorption, facilitate the charge transfer and effectively accelerate the hydrogen evolution reaction. Consequently, the apparent quantum efficiency (AQE) of the designed CdS/P/MoS2 is up to 6.39% at 420 nm, while the H2 evolution rate is boosted to 68.89 mmol·g−1·h−1, which is 10 times higher than that of pristine CdS. This study could provide an alternative strategy for the development of competitive CdS-based photocatalysts as well as noble-metal-free photocatalytic systems toward efficient hydrogen production.
