Preparation of macro-particle Pt-St/DVB and Pt-PTFE and study on their catalytic oxidation performance to HT

The hydrophobic supporter of porous macro-particles ST/DVB and PTFE were prepared by using a two order polymerization method and a reagent method for making holes through dissolving out. On this basis, two types of hydrophobic macro-particle catalysts were prepared by immersing the relevant supporter in H 2PtCl 6 solution. The kinetics of catalytic oxidation of the catalysts to HT and their hydrophobicity were investigated at room temperature.
