Au/ZnO is employed as a photocatalyst for methane oxidation to methanol with 100% selectivity in an oxygen atmosphere at atmospheric temperature.
Pd-deposited 100Cu<sub>2</sub>O exhibits a three-fold improvement in CO<sub>2</sub>reduction than pristine 100Cu<sub>2</sub>O owing to the promoted hole migration and light corrosion resistance, yet no enhancement is observed in 111Cu<sub>2</sub>O–Pd.
Photocatalytic oxidation of methane into formaldehyde in high yield and selectivity remains a grand challenge due to the ineluctable intermediates. Here, we report that a {001}, {010} and {100} facets modified tungsten trioxide photocatalyst enables an intermediate-free oxidation of methane into formaldehyde with 99.4% selectivity. A durable formaldehyde yield of 4.61 mmol g−1 can be achieved after irradiation for 30 h. Mechanism studies disclose that surface defect and reactive lattice oxygen atom are crucial for the selectivity and productivity promotion. This work provides a valid paradigm for efficient conversion of methane to formaldehyde.
We present a novel method to prepare bimetallic Cu–Zn catalysts for electrochemical CO 2 reduction using sputtering and subsequent electrochemical cyclic voltammetry treatment.
