TL;DR: FeOx-supported platinum single-atom and pseudo-single-atom structures are reported as highly active, chemoselective and reusable catalysts for hydrogenation of a variety of substituted nitroarenes.

TL;DR: The key factors affecting the catalytic activity/selectivity, in particular, the geometric and electronic structure of the active sites, are discussed with the aim to extract fundamental principles for the development of efficient and selective catalysts in hydrogenation as well as other transformations.

TL;DR: By using sub-ångström-resolution HAADF-STEM in combination with XPS, XAS, ESR, and Mössbauer spectroscopy, this work has provided solid evidence that Fe is exclusively dispersed as single atoms via forming FeNX and that the relative concentration of each FeNx species is critically dependent on the pyrolysis temperature.

TL;DR: The single-atom Co–N–C catalyst with the structure of CoN4C8-1-2O2 shows excellent performance for the chemoselective hydrogenation of nitroarenes to produce azo compounds under mild reaction conditions.

TL;DR: In this article, an alloyed Pd single-atom catalyst (SAC) was used for the selective hydrogenation of acetylene to ethylene under a simulated front-end hydrogenation process in industry.
