“…Besides CdS quantum dot, Jia et al successfully prepared ZnS–In 2 S 3 –Ag 2 S solid solution coupled with TiO 2–x S x nanotubes film catalyst by a two‐step process of anodization and solvothermal methods . After sovolthermal treatment, the TiO 2 nanotubes still kept their tube‐like structures, and the needle‐like ZnS–In 2 S 3 –Ag 2 S nanorods deposited on the most part of the surface of TiO 2 nanotubes (Figure e,f).…”

Hydrogen production from water splitting by photo/photoelectron‐catalytic process is a promising route to solve both fossil fuel depletion and environmental pollution at the same time. Titanium dioxide (TiO2) nanotubes have attracted much interest due to their large specific surface area and highly ordered structure, which has led to promising potential applications in photocatalytic degradation, photoreduction of CO2, water splitting, supercapacitors, dye‐sensitized solar cells, lithium‐ion batteries and biomedical devices. Nanotubes can be fabricated via facile hydrothermal method, solvothermal method, template technique and electrochemical anodic oxidation. In this report, we provide a comprehensive review on recent progress of the synthesis and modification of TiO2 nanotubes to be used for photo/photoelectro‐catalytic water splitting. The future development of TiO2 nanotubes is also discussed.

“…Experimental results indicated that surface‐doped Zn x Cd 1− x S had a higher hydrogen production rate than the bulk‐doped one due to the new pathways for electron transfer and massive surface active sites. Another practical strategy for bandgap modification of ZnS is to develop solid solutions with narrow bandgap semiconductors, such as Zn 1− x Cd x S, ZnS–AgInS 2 , and ZnS–In 2 S 3 –Ag 2 S, whose bandgap could be modified by chemical composition . The above‐mentioned solid solutions have already shown great potentials in various applications, including protein probing, hydrogen generation, and organic pollutant decomposition …”

ZnS, as one of the first semiconductors discovered and a rising material star, has embraced exciting breakthroughs in the past few years. To shed light on the design principles and engineering techniques of ZnS for improved/novel optoelectronic properties, the fundamental mechanisms and commonly employed strategies are proposed in this review. Recent progress on modifications of ZnS allows it to be extensively and effectively used in versatile applications, including transparent conductors, UV photodetectors, luminescent devices, and catalysis, which are clearly and comprehensively summarized in this work. Novel functional devices springing up from the newly developed ZnS-based materials are highlighted as well. This review not only provides a scientific insight into the advances of ZnS-based materials, but also touches on the future opportunities in this inspiring field.The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/adfm.201802029. relatively high charge recombination rate and low charge transport process inhibit the optoelectronic properties of ZnS as a high-performance photodetector. As a window layer of optoelectronic devices, a lack of high electrical conductivity typically hinders the practical use of ZnS in solar cells, photodiodes, light-emitting devices, etc. As a photocatalyst, the transparency of ZnS becomes a drawback as it suffers from a poor utilization of sunlight.There is not a perfect material, but the potential of developing a material is beyond limitation. The past few years have witnessed extensive designing and engineering of ZnS to explore its potentials in specific applications. [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] This review summarizes the recent breakthroughs on ZnS-based materials as excellent candidates in optoelectronic devices, photocatalysis, and other novel functional devices. More importantly, it sheds light on the design principles and fundamental mechanisms of the improved performance of ZnS through strategies such as developing novel nanostructures, bandgap engineering, alloying with other materials, etc. To the best of our knowledge, it is the first comprehensive review on the design principles and material engineering of ZnS for novel/improved properties and intended applications. Briefly, current literature on a variety of ZnS-based structures was first summarized, ranging from 0D to 2D nanostructures. Then, the representative applications of ZnS-based materials are described, which are mainly consisted of four parts, as shown in Figure 1: transparent conductors, UV photodetectors, luminescent devices, and catalysis. Each part contains the latest design strategies of ZnS for the intended applications, fabrication techniques, representative examples, and the state-of-the-art devices. Finally, it outlines the challenges and opportunities in each field. In particular, we provide our perspectives on the future research directions of ZnS in energy and environment.

Present work mainly focuses on experimental investigation to improvement of hydrogen production by water photoelectrolysis. An experimental facility was designed and constructed for visible light photocatalysis. A series of N-TiO 2 photocatalysts impregnated with platinum on the surface of N-TiO 2 were prepared. Hydrogen production upon irradiating aqueous Pt/N-TiO 2 suspension with visible light was investigated. The shift in excitation wavelength of TiO 2 was 380 nm improved the yield of hydrogen production by N-TiO 2 and Pt/N-TiO 2 . We used a 400 W mercury arc lamp combined with a 400 nm cutoff filter eliminating all the wavelengths under 400 nm. Pt/N-TiO 2 material was characterized with TPR, reflective UV/Visible spectroscopy and TEM. The best hydrogen production rate obtained for this setup for N/Ti = 10, 0.05 wt% Pt/N-TiO 2 , through water splitting was about 772 mmolh -1 g -1 .
