Methane to Methanol through Heterogeneous Catalysis and Plasma Catalysis

Abstract

Direct oxidation of methane to methanol (DOMTM) is attractive for the increasing industrial demand of feedstock. In this review, the latest advances in heterogeneous catalysis and plasma catalysis for DOMTM are summarized, with the aim to pinpoint the differences between both, and to provide some insights into their reaction mechanisms, as well as the implications for future development of highly selective catalysts for DOMTM.

The application of nonthermal plasma in methanol synthesis via CO2 hydrogenation

“…In plasma catalytic partial oxidation of methane using oxidants such as air (or O 2 ), H 2 O 2 , and CO 2 have also been explored for methanol synthesis. [44][45][46][47][48] There are several disadvantages associated with this process. The use of air or O 2 as an oxidant results in high selectivity to CO and CO 2 (CO x ).…”

cis-[6-(Pyridin-2-yl)-1,3,5-triazine-2,4-diamine](dichloride) Palladium(II)-Based Electrolyte Membrane Reactors for Partial Oxidation Methane to Methanol

“…The development of direct conversion of CH 4 to MeOH under ambient conditions to offer a sustainable way for the efficient use of natural resources such as natural gas, shale gas, and biogas is a great goal. 4 Bearing this in mind, scientists have made tremendous efforts to develop methods to produce MeOH. Presently, the electrochemical process using polymer electrolyte reactor-fuel cell type (PER-FC) for partial oxidation of methane in one step under mild conditions (∼80 °C or less) is one of the most successful methods because of the possibility to operate in electrolytic and galvanic modes under continuous flow to simultaneously produce methanol and energy co-generation.…”

The remarkable performance of a single iridium atom supported on hematite for methane activation: a density functional theory study

“…[10][11][12][13] The chemical products based on direct methane conversion have received signicant interest in recent decades from industry and academia due to their more energyefficient and environmental-friendliness. [14][15][16] The rutile IrO 2 surface has been the subject of intensive theoretical [17][18][19] and experimental studies, [20][21][22] among the different catalysts in methane conversion owing to its remarkable reactivity. In addition, much evidence endorses this superior catalytic reactivity and intrinsic electronic characteristics of the IrO 2 surface in methane activation.…”
