TL;DR: Durability tests revealed that the Co single atoms exhibit outstanding chemical stability during electrocatalysis and thermal stability that resists sintering at 900 °C, which could facilitate new discoveries at the atomic scale in condensed materials.

TL;DR: This cathode catalyst with dual metal sites is stable in a long-term operation with 50 000 cycles for electrode measurement and 100 h for H2/air single cell operation, and density functional theory calculations reveal the dual sites is favored for activation of O-O, crucial for four-electron oxygen reduction.

TL;DR: This work adopts metal-organic frameworks (MOFs) to assist the preparation of a catalyst containing single Ni sites for efficient electroreduction of CO2 and presents some guidelines for the rational design and accurate modulation of nanostructured catalysts at the atomic scale.

TL;DR: In this article, the atomically dispersed Pd on graphene can be fabricated using the atomic layer deposition technique, and the single-atom Pd1/graphene catalyst showed about 100% butenes selectivity at 95% conversion at a mild reaction condition of about 50 °C, likely due to the changes of 1,3-butadiene adsorption mode and enhanced steric effect on the isolated Pd atoms.

TL;DR: Experimental and theoretical results demonstrate that lower a coordination number facilitates activation of CO2 to the CO2.- intermediate and hence enhances CO2 electroreduction activity.
