Abstract

A record ethanol production rate of 281.6 μmol g-1 h-1 for the photocatalytic conversion of methane over nitrogen vacancy-rich carbon nitride at room temperature was achieved. Systematic studies demonstrate that the CH4 was activated by the highly reactive ˙OH radicals generated, via H2O2, from the photo-reduction of O2 with H2O.
