Direct methane oxidation over Pt-modified nitrogen-doped carbons.

Nitrogen-doped carbons derived from biomass precursors were modified with Pt(2+) and successfully tested as solid catalysts in the direct oxidation of methane in fuming sulfuric acid. Remarkably, the catalytic performance was found to be substantially better than the Pt-modified Covalent Triazine Framework (CTF) system previously reported, although deactivation is more pronounced for the biomass derived catalyst supports.
