Defective MOFs Microreactor with Heterojunction for Selective Methane Photocatalysis via Desorption-Driven Overoxidation Suppression.

ABSTRACT: Photocatalytic oxidation of methane to methanol oxygenates (CH₃OH and CH₃OOH) under mild conditions represents a promising approach for methane valorization, yet achieving both high efficiency and high selectivity remains a significant challenge. Herein, a defect-engineered spatial coupling strategy is devised to construct a heterojunction photocatalyst (Def-CuCN/NU) by integrating copper single atoms (Cu SA) anchored on polymeric carbon nitride (CN) into the defective NH₂-UiO-66 (Def-NU). The defective MOFs with porous structure and abundant active sites serve as microreactors that enhance methane adsorption and promote methanol desorption, thus promoting the reaction and minimizing the contact of methanol with ·OH radicals and effectively suppressing over
