Photo-Driven Iron-Induced Non-Oxidative Coupling of Methane to Ethane

Huizhen Zhang et al.

Summary: We constructed a solar-energy-driven redox cycle using iron ions as catalysts for the combination of CH4 conversion and H2 production. A photo-driven iron-induced reaction system was developed, which showed high efficiency in the selective coupling of CH4, benzene, and cyclohexane under mild conditions. Mechanistic studies revealed that CH4 coupling was induced by hydroxyl radical generated by photo-driven intermolecular charge migration of an Fe3+ complex. The produced Fe2+ was used to reduce the potential for electrolytic H2 production and then turned back into Fe3+, forming an energy-saving and sustainable recyclable system.

NiO/ZnO heterojunction nanorod catalyst for high-efficiency electrochemical conversion of methane

Cheolho Kim et al.

Summary: Electrochemical conversion shows potential for selective partial oxidation of methane. We propose a NiO/ZnO shell/core nanorod catalyst to enhance electrochemical conversion. The built-in potential at the NiO/ZnO interface and the 1D morphology of the nanorods facilitate fast charge transfer, thereby improving electrochemical methane conversion. By using a 600-nm long NiO/ZnO nanorod catalyst, a high ethanol production rate of 1084.2 mu mol/gNiO/hr with a selectivity of 81% was achieved. Mechanistic analyses with isotopic labeling reactions suggest ethanol production pathways involving the generation of active oxygen, methane activation, and coupling of deprotonated methanol and methane. Enhancement of methane solubility and in situ generation of CO32- from a CH4/CO2 mixture were also explored.

Constructing hollow porous Pd/H-TiO2 photocatalyst for highly selective photocatalytic oxidation of methane to methanol with O2

Xibo Zhang et al.

Summary: In this study, a unique hollow porous nanocage structure was prepared for Pd/ H-TiO2 catalysts to selectively convert methane into methanol under mild conditions with the reaction of O2. The obtained Pd/H-TiO2 exhibited a high methanol production rate of 4.5 mmol/g/h with a selectivity of up to 70% under optimized conditions, surpassing most reported values.
