The research on one-pass oxidation of methane into methanol is a challenge because an active and dynamic catalyst that can work at ambient conditions is yet to be discovered. We demonstrate that the µ-(H2O)-bridged dicopper complex (CuHdatrz) is active for this CH4 oxidation reaction when used as a catalyst with hydrogen peroxide (H2O2) as an oxidant. In-situ synthesis of CuHdatrz on H-ZSM-5 to form a heterogeneously formulated hybrid catalyst (CuHdatrz/H-ZSM-5) improved its capability as a catalyst. It produced 3.1 mmol of total oxygenates at mild reaction conditions. The catalyst was reusable and hence, possesses a high stability, and it energetically involves in the reaction to produce methanol at energy as low as 43.4 kJ/mol.
