The aim of this preliminary work is to compare the efficiency of a catalyst having a titanium dioxide support and Pd-In as metallic additives operating under conventional reaction conditions with that of the same catalyst but irradiated with UV radiation. The purpose of such a comparison is to determine if its photocatalytic activity allows a better control of the reductive function and avoids the formation of undesirable reaction products, specifically nitrites and NH+4. If the results of this exploratory study were attractive enough, possible follow-ups would include the optimization of this catalyst composition and kinetic studies to characterize all the reaction parameters.
