Abstract Upon illumination, photocatalysts generate charge carriers for redox reactions, but their efficiency is often limited by carrier recombination and poor minority-carrier diffusion, despite many existing junction engineering strategies. Here we exploit the insulator–metal transition in VO2 to produce a material that promotes efficient charge separation and enhances the photocatalytic conversion of methane through the spontaneous formation of junctions.
