Dehydrogenation of propane to propene in the presence of CO 2 was investigated over zinc oxide supported on HZSM-5 with high Si/Al ratios. The stability of supported ZnO catalysts for the reaction improves with increasing the Si/Al ratio of the HZSM-5 support, while the catalytic activity shows a contrary trend. A highly active and stable catalyst, ZnO supported on HZSM-5 with a Si/Al ratio...
Nanosized biphase titania photocatalysts with various phase compositions were synthesized by hydrothermal method. Gas-phase photocatalytic oxidations of hexane and methanol were investigated in the presence of the biphase titania catalysts. A clear synergetic effect between the anatase and rutile phases was observed for the two reactions. Mechanical mixtures of the two titania phases were also prepared...
