CO2 (CO) hydrogenation presents the widest route to synthesis of various valuable organic molecules, but precise carbon–carbon coupling control targeted products along with elimination byproducts remains a challenge. We overcome these limitations by synthesizing CeO2-supported dual Pd site catalyst that could actively catalyze conversion into single-product ethanol almost without C1 in continuous-flow fixed-bed reactor. This surprising finding is derived from observation synergistic catalysis between atoms leads extraordinary ability for cleavage C–O bond *CHxOH species and *CHx *CO species. Furthermore, sites be stabilized through enriching situ formed water nano reactor hydrophobic shell layer, thus leading remarkably improved catalytic stability production. As result, as-constructed exhibited superior selectivity at 98.7%, corresponding productivity up 11.6 g per gram hour excellent during continuous test 60 h. Our results demonstrate multifunctional active can break restriction reaction involving single catalyst.

Developing high-performance and cost-effective electrocatalysts for clean renewable energy conversion process has been proved a promising approach to deal with the global environment issues. Single-atom alloy (SAA) catalyst, foreign metal atoms atomically dispersed in surface of host metal, combines merits conventional alloys single-atom catalysts. The maximum atomic utilization active unique structural electrical properties SAA offer great potential boosting electrocatalytic activity reducing cost manufacture. Meanwhile, well-defined sites raise an opportunity shed light on structure-activity relationship further direct synthesis high-efficiency electrocatalysts. Herein, we focus recent developments advanced catalysts discussed general SAAs. Then design principle synthetic methods were summarized. Next, highlighted practical applications SAAs chemicals production, including hydrogen evolution reaction, oxygen CO2 reduction N2 reaction other representative reactions. Finally, challenges future directions are presented.

Alkene functionalization with a single-atom catalyst (SAC) which merges homogeneous and heterogeneous catalysis is fascinating route to obtain high-value-added molecules. However, C–N bond formation of alkene SAC still unexplored. Herein, bimetal-organic framework-derived Co–N/C an atomically dispersed cobalt center reported show good activity chemoselective aziridination/oxyamination reactions from hydroxylamine, late-stage complex alkenes diversified synthetic transformations the aziridine product further expand utility this method. Moreover, system proceeds without external oxidants exhibits mild, atom-economic, recyclable characters. Detailed spectroscopic characterizations mechanistic studies revealed structure catalytic possible intermediates involved in mechanism cycle.
