Abstract
Selective oxidation of methane (CH₄) has attractive potentials for mitigating global warming and producing value-added chemicals, while the activation of highly inert CH₄ remains challenging. Herein, we developed a single-atomic Pt-doped WO₃ (Pt₁-WO₃) catalyst, which enabled to reconstruct polaron states from W to Pt-O sites. This polaron reconstruction allows for fast separation of photogenerated charge carriers and tuning of reactant adsorption sites, and greatly improves the photocatalytic CH₄ activation and conversion efficiency. Under 150 mW·cm⁻² light intensity and aqueous conditions, the Pt₁-WO₃ photocatalyst exhibited a peak CH₄-to-CH₃OH conversion yield of 1151 μmol·gcat⁻¹·h⁻¹ without the use of photosensitizers, sacrificial reagents or strong oxidizers like O₂ or H₂O₂, exceeding the previous reports on photocatalytic CH₄ oxidation under similar conditions, thus suggesting the capability of tuning polaron states for enhanced photocatalysis.
