Facile Synthesis, Characterization and Photocatalytic Activity of MWCNTSupported Metal Sulfide Composites under Visible Light Irradiation

다국어 초록 (Multilingual Abstract)

This paper reported a simple deposition–precipitation method, introducing the metal (Ni, Ag and Sn) and Na2S· 5H2O to preparedispersion metal sulfide nanoparticles on the surface of the Multi-walled carbon nanotube for synthesis of CNT-MxSy (NiS2, Ag2S, SnS) composite photocatalysts. The characterization of the prepared CNT-MxSy (NiS2, Ag2S, SnS) composites was performed by X-ray diffraction, scanning electron microscopy with energy dispersive X-ray analysis and BET analysis. Furthermore, the MB degradation rate constant for CNT-SnS composite was 5.68 × 10−3 under visible light irradiation, which was much higher than the corresponding values for other samples. The detailed formation and photocatalytic mechanism are also provided here.
