Anatase/TiO 2 (B) homojunction nanosheets with a gold cocatalyst for direct photocatalytic coupling of methane to ethane

An anatase/TiO (B) homojunction loaded with Au nanoparticles was synthesized, achieving a C H yield rate of 170 μmol g h in a flow photoreactor. The homojunction reduces TiO (B)'s strong oxidative ability, offering a more moderate environment for methane dehydrogenation, while Au aids in charge mitigation and methyl radical coupling. The catalyst highlights homojunction engineering and a ternary synergistic effect in photocatalytic CH coupling.
