Enhanced Photocatalytic Oxidative Coupling of Methane over Metal-Loaded TiO₂ Nanowires.

ABSTRACT: The photocatalytic oxidative coupling of methane (OCM) on metal-loaded one-dimensional TiO₂ nanowires (TiO₂ NWs) was performed. With metal loading, the electric and optical properties of TiO₂ NWs were adjusted, contributing to the improvement of the activity and selectivity of the OCM reaction. In the photocatalytic OCM reaction, the 1.0 Au/TiO₂ NW catalyst exhibits an outstanding C₂H₆ production rate (4901 μmol g^-1 h^-1) and selectivity (70%), alongside the minor production of C₃H₈ and C₂H₄, achieving a total C₂-C₃ hydrocarbon selectivity of 75%. In contrast, catalysts loaded with Ag, Pd, and Pt show significantly lower activity, with Pt/
