TL;DR: Fe-N-C materials quasi-free of crystallographic iron structures after argon or ammonia pyrolysis are synthesized, demonstrating that the turnover frequency of Fe-centred moieties depends on the physico-chemical properties of the support.

TL;DR: The effect of the nature of 3d-metal within a series of M-N-C catalysts on electrocatalytic activi-ty/selectivity for ORR (H2O2 and H2O products) and H 2O2 reduction reaction (H1O2RR) is investigated.

TL;DR: It is concluded that cobalt-based moieties bind O2 too weakly for efficient O2 reduction, and nitrogen-doped carbon materials with atomically dispersed iron or cobalt are promising for catalytic use.

TL;DR: In this article, a series of iron-based catalysts synthesized by pyrolysis of Fe-, N-, and C-containing precursors for the electroreduction of CO2 to CO under aqueous conditions were investigated.

TL;DR: This work reports on an inexpensive Cu-N-C material prepared via a simple pyrolytic route that exclusively feature single copper atoms with a CuN4 coordination environment, atomically dispersed in a nitrogen-doped conductive carbon matrix that achieves aqueous CO2 electroreduction to ethanol at a Faradaic yield of 55% under optimized conditions.
