Selective Oxidation of Methane to Methanol on Cu/SBA-15 Via a Stepwise Manner

摘要

Abundant and cheap resources containing methane such as natural gas, methane hydrates, and biogas have been considered as promising alternatives to decline the dependence of chemical and energy industries on crude oil. However, unsafe and costly transportation and storage, and high chemical inertness of methane cause an underutilization of these resources at present. The direct conversion of methane to more energy-dense liquid derivatives such as methanol is an economically efficient protocol to promote the application of methane. Although great interest and numerous efforts have been devoted to the hydroxylation of methane, unfortunately, the development of a commercially viable catalytic process with a high yield of methanol remains unsolved.
