Precise constructed atomically dispersed Fe/Ni sites on porous nitrogen-doped carbon for oxygen reduction

Activated carbon supported Fe–Cu–NC as an efficient cathode catalyst for a microbial fuel cell

“…The mesopores could allow oxygen to enter the catalytic active sites and promote the transportation of substances, which could improve the ORR activity. 47 As compared with the AC-control, the surface area and pore volume of Fe–Cu–NC- x were slightly reduced, which might be due to the fact that Fe–Cu–NC nanoparticles occupied the partial mesopores of AC.…”

Core–shell structured Fe–N–C wrapped by an ultrathin porous carbon shell as a robust electrocatalyst for the oxygen reduction reaction

“…2f). 34 Notably, Fe-N was located at 398.6 AE 0.2 eV, which is very close to the pyrrolic-N, providing evidence for the coordination of Fe atoms with N atoms. 35 The relative contents of pyridinic N species were calculated, and were found to be greatly enhanced on the Fe-N-C@NC surface (55.46%) compared to that on Fe-N-C (42.67%).…”

“…20e). More importantly, the activity of (Fe,Co)/N-C was significantly higher than that of the single active metal FeNi SAs/NAC catalysts were obtained from the pyrolysis of ZIF-8@FeNi(mIm) x precursor by Bai et al 225 (Fig. 20g).…”
