title: Low-Temperature Transformation of Methane to Methanol on Pd1O4Single Sites Anchored on the Internal Surface of Microporous Silicate.
abstract: 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.
