Abstract
The composite photocatalyst NixMo1âxS2/MOF-5@g-C3N4 was successfully synthesized by means of hydrothermal with two step methods and the effective photocatalytic activity improvement was obtained. With the introduction of NixMo1âxS2, the H2 production reached the maximum about 319 μmol under continuous visible light irradiation for 5 h, which was 30 times higher than that of pure g-C3N4 photocatalyst. A series of characterization results shown that the MOF-5@g-C3N4 on the surface of NixMo1âxS2 provided the more active sites and improved the efficiency of photo-generated charge separation with SEM, XRD, TEM, EDX, XPS, UV-vis DRS, BET, FTIR, transient fluorescence and electro-chemistry etc. and the results of which were in good mutual corresponding with each other. Furthermore, the reaction mechanism over the compound catalyst Nix-Mo1âxS2/MOF-5@g-C3N4 was proposed.
