Direct Oxidation of Methane to Methanol Enabled by Electronic Atomic Monolayer–Metal Support Interaction

Methane oxidation by aqueous osmium tetroxide and sodium periodate: inhibition of methanol oxidation by methane.

Response to Comment on “Selective anaerobic oxidation of methane enables direct synthesis of methanol”

Periana argues that the stepwise reaction of methane with water is thermodynamically unfavorable and therefore impractical. We reply by presenting an in-depth thermodynamic analysis of each step in the process and show that the surface concentrations of the reactants and products as well as the stabilizing effect of additional water molecules, as discussed in the original paper, fully support t...

Methanol promotes atmospheric methane oxidation by methanotrophic cultures and soils.

Two methanotrophic bacteria, Methylobacter albus BG8 and Methylosinus trichosporium OB3b, oxidized atmospheric methane during batch growth on methanol. Methane consumption was rapidly and substantially diminished (95% over 9 days) when washed cell suspensions were incubated without methanol in the presence of atmospheric methane (1.7 ppm). Methanotrophic activity was stimulated after methanol (...

Comment on "Selective anaerobic oxidation of methane enables direct synthesis of methanol".

The comment and response concerning the report of oxidation of methane to methanol by water (Reports, 5 May 2017, p. 523) do not fully capture the implications of thermodynamic limitations. A nonisothermal process in which each cycle requires a large temperature swing and permits only substoichiometric methane conversion surely could not be carried out on any practical scale.

Selective oxidation of methane to methanol catalyzed, with C-H activation, by homogeneous, cationic gold.

Some of the most efficient homogeneous catalysts for the lowtemperature, selective oxidation of methane to functionalized products employ a mechanism involving C H activation with an electrophilic substitution mechanism. Several such systems have been reported based on the cations Hg, Pd, and Pt. These catalyst systems typically operate by two general steps that involve: A) C H activation by co...
