Effect of Supported Pt on Reduction and Sulfidation of Mo Based Catalysts
Abstract:
Effect of supported Pt on reduction and sulfidation for Pt/MoO3 and Pt/MOS2 catalysts were studied by pulse reduction-sulfidation, flow reduction-sulfidation, temperature programmed electrical conductivity, temperature programmed reduction technique and X ray diffraction analysis. It was found that, for Pt/MoO3 the addition of Pt greatly promoted the reduction and sulfidation of MoO3, it was also shown that, for Pt/MoS2 Pt obviously facilitated the reduction of MoS2 to form S-vacancy, leading to an increment of the concentration of coordinative unsaturated molybdenum.
