Synthesis of a Hybrid Composed of Anisotropic Niobate Layers Modified with MoC Nanoparticles

Meilin Du, Yusuke Asakura, Takuma Kamibe, Yusuke Yamauchi, Yoshiyuki Sugahara

Summary: A hybrid material consisting of anisotropic niobate layers modified with MoC nanoparticles was synthesized through multistep reactions. Stepwise interlayer reactions induced selective surface modification at alternate interlayers, leading to the formation of double-layered nanosheets after ultrasonication. Liquid phase MoC deposition with the double-layered nanosheets resulted in the decoration of MoC nanoparticles on their surfaces. The hybrid can be considered as a stacking of two layers with anisotropically modified nanoparticles. The hybridization method showed potential for the synthesis of semiconductor nanosheets and co-catalyst nanoparticles for photocatalytic applications, as evidenced by the photocatalytic activity exhibited by the heated hybrid material.

Morphology Control of Transition Metal Oxides by Liquid-Phase Process and Their Material Development

Shu Yin, Takuya Hasegawa

Summary: The functionality of inorganic materials depends on their chemical composition, morphology, particle size, and crystal facet, which are influenced by the synthesis process. Precise control of the synthesis process can lead to the discovery of new functionality and improvement of materials. Solution processes allow for precise control of morphology and particle size, and are strongly related to the dissolution reprecipitation mechanism, enabling strict control of material composition and formation of highly crystalline particles. This review focuses on the role of solvents in the solution process, their effect on particle size and morphology of transition metal oxides, related functional improvements, direct formation of functional thin films, and morphology control by non-oxide materials through topotactic reactions.

WS2/In2S3 composite photocatalyst for photocatalytic H2 generation and pollutant degradation

Bingrong Guo, Bin Liu, Chaoli Wang, Yuhua Wang, Shu Yin, Weihua Han

Summary: The recombination of photocarriers is a crucial factor affecting the performance of photocatalysts. The design of heterojunction photocatalysts can effectively inhibit the recombination by enhancing photocarrier separation and transport. In this study, a Z-scheme WS2/In2S3 photocatalyst with a bi-layered sheet-like structure was synthesized. The unique architecture of this photocatalyst reduced the charge transfer distance and provided more surface area, promoting the photocatalytic reaction. The Z-scheme structure effectively separated and retained the strong redox capability of the photocarriers, resulting in remarkable photocatalytic activity for H-2 generation and tetracycline hydrochloride degradation. The Z-scheme WS2/In2S3 composite showed the highest H-2 generation rate of 592.9 mu mol g(-1) h(-1) and the best degradation efficiency of 90% within 60 min. The bi-layered Z-scheme photocatalyst also demonstrated excellent stability and recyclability.
