Abstract The selective conversion of ethane (C 2 H 6 ) to ethylene 4 under mild conditions is highly wanted, yet very challenging. Herein, it demonstrated that a Pt/WO 3−x catalyst, constructed by supporting ultrafine Pt nanoparticles on the surface oxygen‐deficient tungsten oxide (WO nanoplates, efficient and reusable for photocatalytic C dehydrogenation produce with high selectivity. Specifically, pure light irradiation, optimized photocatalyst exhibits yield rates 291.8 373.4 µmol g −1 h , respectively, coupled small formation CO (85.2 CH (19.0 ), corresponding selectivity 84.9%. Experimental theoretical studies reveal vacancy‐rich WO catalyst enables broad optical harvesting generate charge carriers working redox reactions. Meanwhile, cocatalyst reinforces adsorption desorption key reaction species, separation migration light‐induced charges promote productivity In situ diffuse reflectance infrared Fourier transform spectroscopy density functional theory calculation expose intermediates formed during reaction, which permits construction possible mechanism.

Lattice oxygen (LO)-mediated photothermal dry reforming of methane (DRM) presents a promising approach to syngas production. However, realizing high DRM efficiency and durability remains challenging due the difficulty in activating LOs catalysts. Herein, we demonstrate that partially substituting Fe sites perovskite ferrite (LaFeO3) by Mn triggers LOs, bestowing catalyst with superior activity stability for after modification Ru. The exchange induces charge transfer from La Mn, which combined incoming photoexcited electrons reconstructs perovskite's electronic structure, weakening La-O-Mn bonds facilitating LO migration. Meanwhile, photogenerated holes migrate surface further enhancing their reactivity mediate DRM. Under light irradiation, exhibits an outstanding production rate (H2: 42.89 mol gRu-1 h-1, CO: 54.92 h-1) while stably operating over 150 h. It also achieves turnover frequency 0.9 s-1 light-to-chemical energy 15.3%, setting benchmark light-driven performance. This work underscores significance exact site doping metal oxides fine-tune activity, providing valuable guidance fabricating efficient catalysts solar-powered redox reactions proceeded via light-supported Mars-van Krevelen mechanism.
