Gas-Phase Selective Oxidation of Methane into Methane Oxygenates

Methane is an abundant resource and its direct conversion into value-added chemicals has been attractive subject for efficient utilization. This method can be more than the present energy-intensive indirect of methane via syngas, a mixture CO H2. Among various approaches conversion, selective oxidation oxygenates (e.g., methanol formaldehyde) particularly promising because it proceed at low temperatures. Nevertheless, due to product yields this challenging. Compared with liquid-phase partial methane, which frequently demands strong oxidizing agents in protic solvents, gas-phase some merits, such as possibility using oxygen oxidant ease scale-up owing use heterogeneous catalysts. Herein, we summarize recent advances oxygenates, focusing mainly on formaldehyde methanol.
