MoS2 Nanosheets Assembled on Three-Way Nitrogen-Doped Carbon Tubes for Photocatalytic Water Splitting
Frontiers in chemistry, 2019Co-Authors: Yujia Zhang, Ping Chen, Yingqiang Zhao, Bo TangAbstract:In this work, a micron-sized three-way nitrogen-doped carbon tube covered with MoS2 nanosheets (TNCT@MoS2) was synthesized and applied in Photocatalytic Water Splitting without any sacrificial agents for the first time. The micron-sized three-way nitrogen-doped carbon tube (TNCT) was facilely synthesized by the calcination of commercial sponge. The MoS2 nanosheets were assembled on the carbon tubes by a hydrothermal method. Compared with MoS2, the TNCT@MoS2 heterostructures showed higher H2 evolution rate, which was ascribed to the improved charge separation efficiency and the increased active sites afforded by the TNCT.

Efficient energy-level modification of novel pyran-annulated perylene diimides for Photocatalytic Water Splitting
Chemical Communications, 2017Co-Authors: Ran Wang, Wen Wang, Gang Li, Andong Zhang, Jianfeng Zhao, Bo TangAbstract:We design and synthesize four pyran-embedded perylene diimide (PDI) compounds through a straightforward methodology. UV-driven Photocatalytic Water Splitting using the compounds as photocatalysts demonstrates that the highest Photocatalytic H2 evolution rate under UV light is 0.90 mmol g−1 h−1, which paves the way towards organic photoresponsive materials.

ir driven Photocatalytic Water Splitting with wo2 naxwo3 hybrid conductor material
Nano Letters, 2015Co-Authors: Wen Wang, Ning Deng, Bo TangAbstract:An IR-driven Photocatalytic Water Splitting system based on WO2–NaxWO3 (x > 0.25) hybrid conductor materials was established for the first time; this system can be directly applied in seaWater. The WO2–NaxWO3 (x > 0.25) hybrid conductor material was readily prepared by a high-temperature reduction process of semiconductor NaxWO3 (x < 0.25) nanowire bundles. A novel ladder-type carrier transfer process is suggested for the established IR-driven Photocatalytic Water Splitting system.

earth abundant cocatalysts for semiconductor based Photocatalytic Water Splitting
Chemical Society Reviews, 2014Co-Authors: Jun Zhang, Jiaguo Yu, Mietek Jaroniec, Shizhang QiaoAbstract:Photocatalytic Water Splitting represents a promising strategy for clean, low-cost, and environmental-friendly production of H2 by utilizing solar energy. There are three crucial steps for the Photocatalytic Water Splitting reaction: solar light harvesting, charge separation and transportation, and the catalytic H2 and O2 evolution reactions. While significant achievement has been made in optimizing the first two steps in the Photocatalytic process, much less efforts have been put into improving the efficiency of the third step, which demands the utilization of cocatalysts. To date, cocatalysts based on rare and expensive noble metals are still required for achieving reasonable activity in most semiconductor-based Photocatalytic systems, which seriously restricts their large-scale application. Therefore, seeking cheap, earth-abundant and high-performance cocatalysts is indispensable to achieve cost-effective and highly efficient Photocatalytic Water Splitting. This review for the first time summarizes all the developed earth-abundant cocatalysts for Photocatalytic H2- and O2-production half reactions as well as overall Water Splitting. The roles and functional mechanism of the cocatalysts are discussed in detail. Finally, this review is concluded with a summary, and remarks on some challenges and perspectives in this emerging area of research.

Photocatalytic Water Splitting on Au/HTiNbO5 nanosheets
International Journal of Hydrogen Energy, 2014Co-Authors: Yung Shun ChangAbstract:Abstract The layered potassium titanium niobate, KTiNbO5, is known as a photocatalyst for hydrogen production from Water Splitting under UV light. Here we show that titanium niobate nanosheets with a slit like framework can be obtained by exfoliation of KTiNbO5 followed by proton exchange. Gold nanoparticles were deposited on the titanium niobate nanosheets using deposition-precipitation (DP), photo-deposition (PD) and impregnation (IMP) method in order to improve Photocatalytic hydrogen production from Water Splitting. These catalysts were characterized by powder X-ray diffraction patterns (XRD), inductively coupled plasma mass spectrometry (ICP-MS), UV–visible spectroscopy (UV–vis), and Transmission Electron Microscopy (TEM). The gold loaded titanium niobate nanosheets prepared by the DP method consisted of a good metal-semiconductor interface which allowed for a much higher efficient electron–hole separation. In this paper, we developed a facile method of preparing titanium niobate nanosheets containing gold nanoparticles. The titanium niobate nanosheets with Au cocatalyst prepared by the DP method showed a uniform dispersion of gold nanoparticles with an average gold particle size of 3 nm and exhibited an ultra-high Photocatalytic Water Splitting activity, which was 56 times higher than that exhibited by the origin KTiNbO5 photocatalyst.

Photocatalytic Water Splitting for hydrogen production on Au/KTiNbO5
International Journal of Hydrogen Energy, 2010Co-Authors: Yung Shun ChangAbstract:Abstract Gold nanoparticles were deposited on potassium titanoniobate, KTiNbO 5 using deposition-precipitation (DP), conventional impregnation (IMP) and photodeposition method in order to improve Photocatalytic hydrogen production from Water Splitting. The effect of synthesis pH value of a HAuCl 4 aqueous solution used in the DP process on the morphology of gold nanoparticles, optical property and Photocatalytic activity of Water Splitting under UV light irradiation was investigated. These catalysts were characterized by powder X-ray diffraction patterns (XRD), inductively coupled plasma mass spectrometry (ICP-MS), UV–visible spectroscopy (UV–vis), and Transmission Electron Microscopy (TEM). The Au/KTiNbO 5 catalysts prepared by the DP method consisted of a good metal–semiconductor interface which allowed for a much higher efficient electron-hole separation. The 0.63 wt% Au/KTiNbO 5 catalyst prepared by the DP method at pH = 10 showed a uniform dispersion of gold nanoparticles with an average gold particle size of 4.2 nm and exhibited an ultra-high Photocatalytic Water Splitting activity (3522 μmol g −1 h −1 ), about 47 times higher than that exhibited by the KTiNbO 5 photocatalyst.
