Highly efficient oxidation of methane into methanol over Ni-promoted Cu/ZSM-5.

ABSTRACT: Direct functionalization of methane in natural gas is of paramount importance but faces tremendous challenges. We reported a nickel-modified copper zeolite catalyst for the selective oxidation of methane into methanol. Using H₂O₂ as an oxidant in the liquid phase at 80 °C, Cu₁Ni_0.75/ZSM-5 catalyst presented a relatively high methanol yield of 82 162 μmol g_cat ^-1 h^-1 (with a methanol selectivity of ∼74%). Combining series of designed experiments and thorough characterization analysis, including electron microscopy, X-ray photoelectric spectroscopy, Fourier transform infrared reflection as well as in situ diffuse reflectance infrared Fourier transform spectroscopy, abundant Cu^I active sites were fo
