Direct conversion of methane to chemical feedstocks such as methanol under mild conditions is a challenging but ideal solution for utilization of methane. Pd1O4single-sites anchored on the internal surface of micropores of a microporous silicate exhibit high selectivity and activity in transforming CH4to CH3OH at 50–95 °C in aqueous phase through partial oxidation of CH4with H2O2. The selectivity for methanol production remains at 86.4 %, while the activity for methanol production at 95 °C is about 2.78 molecules per Pd1O4site per second when 2.0 wt % CuO is used as a co-catalyst with the Pd1O4@ZSM-5. Thermodynamic calculations suggest that the reaction toward methanol production is highly favorable compared to formation of a byproduct, methyl peroxide.

This study was made to resolve the apparent discrepancy between the finite rate constants observed for the CH3O2 reaction with SO2 in high-intensity flash photolysis and near zero values observed recently by us and others for this reaction in NO-free, CH3O2-SO2 experiments at low intensity.

Product studies were made with the FT IR method in the photooxidation of CH3N2CH3 and in the Cl-atom initiated oxidation of CH4 in O2-N2 mixtures at 700 torr and 297 K.The major products were CH2O, CH3OH, and CH3O2H in both systems.A weak, broad absorption band centered at 1030 cm-1 was assigned tentatively to CH3O2CH3.These results are consistent with the following primary and secondary reactions: (primary) 2CH3O2 ---> 2CH3O + O2 (1a); 2CH3O2 ---> CH3OH + CH2O + O2 (1b); 2CH3O2 ---> CH3O2CH3 + O2 (1c); (secondary) CH3O + O2 ---> CH2O + HO2 (5); CH3O2 + HO2 ---> CH3O2H + O2 (6).The relative rate costants for reactions 1a-c were determined to be k1a:k1b:k1c = 0.32 : 0.60 : 0. 08, respectively.
