Spatially Decoupling Redox Sites on TiO2 via Ag–Cr Co-Modification for Highly Selective Photocatalytic Methane Coupling
Photocatalytic oxidative coupling of methane (OCM) presents a promising route for the direct conversion of methane into value-added hydrocarbons, yet it remains challenged by the need to balance efficient methane activation with the suppression of overoxidation. Herein, we report a Ag–Cr co-modified TiO2 photocatalys...
