“…The photocurrent started to decrease, possibly ascribing to the photo-oxidation or photocorrosion that occurred on the composite 3 through accumulated photoinduced holes [31], and then it kept up a steady trend under visible-light irradiation [60]. Noticeable, it exhibited outstanding long-term operation stability beyond 32 h, which was in agreement with the previous XRD and high-resolution XPS analysis [30,65].…”

“…Whereas a decrease of photocurrent density was given in excess of 15 wt% Ag NPs for other composites. The reason may be that much more Ag NPs accumulated in the system, shielding the active sites, resulting in lower optical absorption for the hybrid [65].…”

“…As displayed in Figure c, CZ 0.15 S‐0.2M has a much higher photocurrent density than O‐MoS 2 , CZ 0.15 S, and CZ 0.15 S‐5M, indicating that the former functions better in producing and transferring charge carriers, responsible for its superior photocatalytic activity. In good agreement with the photocurrent response result, the lower photoluminescence (PL) emission (originating from the excitonic or trapped emission) intensity of CZ 0.15 S‐0.2M reveals it to possess a stronger ability in suppressing the recombination of electron–hole pairs . Moreover, the electrochemical impedance spectroscopy (EIS) measurement was carried out to further study the charge‐transfer process under visible‐light illumination.…”

Development of noble‐metal‐free photocatalysts for highly efficient sunlight‐driven water splitting is of great interest. Nevertheless, for the photocatalytic H2 evolution reaction (HER), the integrated regulation study on morphology, electronic band structures, and surface active sites of catalyst is still minimal up to now. Herein, well‐defined 1D Cd1−xZnxS@O‐MoS2/NiOx hybrid nanostructures with enhanced activity and stability for photocatalytic HER are prepared. Interestingly, the band alignments, exposure of active sites, and interfacial charge separation of Cd1−xZnxS@O‐MoS2/NiOx are optimized by tuning the Zn‐doping content as well as the growth of defect‐rich O‐MoS2 layer and NiOx nanoparticles, which endow the hybrids with excellent HER performances. Specifically, the visible‐light‐driven (>420 nm) HER activity of Cd1−xZnxS@O‐MoS2/NiOx with 15% Zn‐doping and 0.2 wt% O‐MoS2 (CZ0.15S‐0.2M‐NiOx) in lactic acid solution (66.08 mmol h−1 g−1) is about 25 times that of Pt loaded CZ0.15S, which is further increased to 223.17 mmol h−1 g−1 when using Na2S/Na2SO3 as the sacrificial agent. Meanwhile, in Na2S/Na2SO3 solution, the CZ0.15S‐0.2M‐NiOx sample demonstrates an apparent quantum yield of 64.1% at 420 nm and a good stability for HER under long‐time illumination. The results presented in this work can be valuable inspirations for the exploitation of advanced materials for energy‐related applications.

Ternary chalcogenide semiconductor, cadmium indium sulfide (CdIn 2 S 4 ), was prepared by a simple solvothermal method using ethylene glycol as a solvent, as well as indium chloride tetrahydrate (InCl 3 . 4H 2 O), cadmium nitrate tetrahydrate [Cd(NO 3 ) 2 . 4H 2 O], and thiacetamide (TAA) as precursors. The resulted sample was subject to a series of characterizations. It is the first time to use CdIn 2 S 4 sample as a visible light-driven photocatalyst for simultaneous selective redox transformation of organic aromatic compounds. The results indicate that the as-synthesized CdIn 2 S 4 photocatalyst not only has excellent photocatalytic performance compared with pure In 2 S 3 and CdS for the selective oxidation of aromatic alcohols in an oxygen environment, but also shows high photocatalytic redox activities under nitrogen atmosphere. A possible mechanism for the photocatalytic redox reaction in the coupled system was proposed. It is hoped that our current work could extend the applications of CdIn 2 S 4 photocatalyst and provide new insights for selective transformations of organic compounds.The photocatalytic technology has attracted much attention for the scholars of different fields since Fujishima and Honda found that TiO 2 as electrode can decompose water to produce hydrogen and oxygen in 1972 1 . With the development of photocatalytic technology, current research work mainly focuses on the degradation of organic pollutants 2-4 , hydrogen production in water 5 , reduction of carbon dioxide 6 , selective oxidation of different alcohols 7 , and other kinds of organic transformation reactions [8][9][10] . Among them, selective oxidation of alcohols to corresponding aldehydes without further oxidation to carboxylic acids and carbon dioxide has become a research hotspot recently 11,12 . This is because that the selective oxidation of aromatic alcohols into corresponding aldehydes is one of the most fundamental reactions in organic synthesis and fine chemical industry 13 . Traditional oxidants and reductants, such as KMnO 4 , ClO − , Fe, and Pt used in the redox process generally have toxicity, corrosivity, or preciousness. Additionally, these reaction systems are not only quite complicated, but also produce a lot of wastes. Therefore, one of the challenges as well as opportunities faced by the researchers is to develop a high-efficienct and environmental friendly method for selective organic transformations under mild conditions 14 .It has been reported that semiconductor photocatalysts can be applied in the selective oxidation of alcohols to aldehydes rather than CO 2 and H 2 O in the final products 15 . For example, Xu's group reported that CdS was introduced as an efficient visible light photocatalyst for selective oxidation of saturated primary C-H bonds under ambient conditions 16 . Panda's group found efficient photocatalytic selective nitro-reduction and C-H bond oxidation over ultrathin sheet mediated CdS flowers 17 . Wang and his coworkers reported molecular and textural engineering of conjugated carbon...
