Paper Abstract

The influence of the monochromatic light with different wavelength on the catalytic activity and selectivity of SiO2 and zirconium polyphosphates was studied. It was shown that the wavelength of the falling irradiation differently influence on the rates of isopropyl alcohol dehydration and dehydrogenation on SiO2 surface. The influence of the falling irradiation on the catalytic activity and selectivity of zirconium polyphosphates in the reaction of isopropyl alcohol conversion depends both on the wavelength of the falling irradiation and the composition of the samples. The change of the catalytic properties was explained by the selective influence of the short-wave irradiation on the structural water state and the variation of the number and condition of active centers of the catalysts surface during the exposure.
