Single-atom catalysts are promising platforms for heterogeneous catalysis, especially clean energy conversion, storage, and utilization. Although great efforts have been made to examine the bonding oxidation state of single-atom before and/or after catalytic reactions, when information about dynamic evolution is not sufficient, underlying mechanisms often overlooked.

Photocatalysis provides an intriguing approach for the conversion of methane to multicarbon (C2+) compounds under mild conditions; however, with methyl radicals as sole reaction intermediate, current C2+ products are dominated by ethane, a negligible selectivity toward ethylene, which, key chemical feedstock, possesses higher added value than ethane. Herein, we report direct photocatalytic methane-to-ethylene pathway involving formation and dehydrogenation alkoxy (i.e., methoxy ethoxy)...
Abstract Nonoxidative coupling of methane (NOCM) is a highly important process to simultaneously produce multicarbons and hydrogen. Although oxide-based photocatalysis opens opportunities for NOCM at mild condition, it suffers from unsatisfying selectivity durability, due overoxidation CH 4 with lattice oxygen. Here, we propose heteroatom engineering strategy active, selective durable photocatalytic NOCM. Demonstrated by commonly used TiO 2 photocatalyst, construction Pd–O in surface reduces...
