Graphical Abstract

Radically Improved: OH radicals formed by quasi-equilibrated steps on oxide surfaces introduce homogeneous pathways that lead to higher rates and C₂ yields in oxidative methane coupling relative to those attained by CH₄ activation with chemisorbed oxygen (see picture; O*: dissociated oxygen atom; R: abstractor). The reactivity of OH^. leads to a weaker influence of the CH bond energies on the relative rates of H abstraction from CH₄, C₂H₆, and C₂H₄.
