Photoimmobilized catalysts for low-temperature oxidation of olefins

The catalytic oxidation of light olefins on complex oxide catalysts is known to proceed at temperatures above 630 K. Promising catalysts for the low temperature oxidation of hydrocarbons can be heterogeneous metal complexes whose efficiency is largely determined by the method of their preparation. We have developed a new nontraditional method to synthesize heterogeneous metal complex catalysts, which distinguishes by using W-irradiation directly in the process of complex immobilization on the support[1-3]. Here we present the results of studying the oxidation of propene to acrolein and isobutene to methacrolein on metal complex catalysts synthesized through photochemical reactions. We have established that the application of photoimmobilized metal complex catalysts decreases the reaction temperature from 630 K to 300-320 K at selectivity about 100 %.
