Effect of the reaction conditions on the performance of Au-Pd/TiO(2) catalyst for the direct synthesis of hydrogen peroxide.
The direct synthesis of hydrogen peroxide from H(2) and O(2) has been studied using a high activity AuPd/TiO(2) catalyst. In particular, the effect of variation in the reaction conditions on the productivity of hydrogen peroxide formation is investigated in detail. The effect of H(2)/O(2) molar ratio, temperature, total pressure and solvent composition has been studied and optimised conditions identified. In addition, the effect of carrying out the synthesis reaction in the presence of hydrogen peroxide is investigated and the competing reactions of hydrogen peroxide formation, decomposition and hydrogenation are discussed and optimal operating conditions are identified.
