High H(2)O(2) Utilization Promotes Selective Oxidation of Methane to Methanol at Low Temperature

Selective oxidation of methane to methanol has been often considered as a “holy grail” reaction in catalysis. Herein, we systematically investigate the effect of solution pH and Pd-to-Au ratio of AuPd(x) colloid on the catalytic performance of methane oxidation. It is revealed that these two paramet...

description Selective oxidation of methane to methanol has been often considered as a “holy grail” reaction in catalysis. Herein, we systematically investigate the effect of solution pH and Pd-to-Au ratio of AuPd(x) colloid on the catalytic performance of methane oxidation. It is revealed that these two parameters can determine the amount of H(2)O(2) participated in the reaction, which is linearly related to the productivity of oxygenates. A high catalytic performance in methane activation requires a high utilization of H(2)O(2) to generate more ·OH. The optimal pH is 3.0 and the optimal Pd-to-Au ratio is between 0.1 to 0.7.
