Abstract:
The kinetics of low-temperature (10–50°C) oxidation of CO in the presence of a homogeneous catalytic system consisting of Pt halide complexes and phosphomolybdic heteropolyacid doped with vanadium(V) atoms was studied. A heteropolyacid solution, used as an example, with a low content of catalytically active vanadium atoms (Н7РМо8V4O40), the optimal process conditions (CO concentration, content of Pt and halide ions, pH) were determined, a kinetic equation was derived, and a mechanism was proposed. It was shown that the introduction of catalytic amounts of palladium salt makes it possible to eliminate the induction period of the CO oxidation reaction, as well as to increase the stability of the catalytic system. Significant activity and stability of the combined system Pt + Pd + Н10Р3Мо18V7O84 was demonstrated.
