Hydrodechlorination of Carbon Tetrachloride and 1,2-Dichloroethane on Palladium Nanoparticles Supported on Metal Fluorides

Abstract

Catalytic activity of palladium supported on strongly acidic aluminum fluoride or on much less acidic magnesium fluoride has been the subject of current research. Both catalysts were synthesized by non-aqueous sol-gel method with subsequent two-stage activation: post-fluorination and reduction. The catalytic behavior of prepared Pd/HS-AlF 3 and Pd/HS-MgF 2 in the hydrodechlorination reactions of chlorinated hydrocarbons was investigated. It was found that differences in support acidity and catalyst's activation protocol strongly effect the catalytic performance.
