Abstract: Compared to MoS 2 (001), the synergetic effect between the single Cu site and S vacancy on Cu/MoS 2 (001) destabilizes O, which not only increases the CO hydrogenation rate by 5 orders of magnitude, but leads to the selectivity switch from CH 4 to CH 3 OH.

Abstract: Regardless of the functionals used and the presence of graphitic carbon, the CO methanation rate on Co(0001) is mainly controlled by CHO decomposition.

Abstract: Atomically dispersed Fe−N−C electrocatalysts have displayed excellent catalytic performances towards the oxygen reduction reaction (ORR), while the identification of the genuine active sites remains a challenge. Herein, we report a Fe−N−C electrocatalyst of FeSA/HNPC featuring single‐atomic FeN 4 sites on hierarchically N‐doped porous carbon (HNPC), which shows a very competitive ORR activity in alkaline solution even at a low electrocatalyst loading of 0.2 mg cm −2 on the working electrode. A comparison of energy barriers in ORR reveals that the single‐atomic FeN 4 active sites in FeSA/HNPC existing in the form of pyrrole‐N 4 −Fe is more favorable than that of pyridine‐N 4 −Fe for the enhanced ORR activity. Understanding the nature of FeN 4 active sites will greatly benefit the design of Fe−N−C electrocatalysts with highly effective ORR performances.
