Reinforced atomically dispersed Fe N C catalysts derived from petroleum asphalt for oxygen reduction reaction

A lignin-derived flexible porous carbon material for highly efficient polyselenide and sodium regulation

“…S2B†). 46 The N 1s spectrum reveals the existence of N–O, graphitic N, Fe–N x , and pyridinic N in the Fe-BC (Fig. S2C†).…”

“…S2C †). 46 Furthermore, the Fe 2p spectrum can be deconvoluted into spin-orbit doublets of Fe 2p 1/2 (722.3 eV) and Fe 2p 2/3 (709.6 eV) peaks of Fe 2+ , as well as Fe 2p 1/2 (726.1 eV) and Fe 2p 2/3 (714.2 eV) peaks of Fe 3+ (Fig. S2D †).…”

“…S2D †). 46 After mixing the prepared Fe-BC with the GO solution and filtrating it into a film, the prepared Fe-BC/rGO shows a relatively compact contact structure between Fe-BC and graphene (Fig. S1B †), which benefits the continuous transfer of Na + /e − .…”

Suppressing H2O2 formation in the oxygen reduction reaction using Co-doped copper oxide electrodes

“…Fe-N-C) have also gained attention in recent times as active materials that can substitute the use of Pt. [8][9][10] The overall reactivity of catalyst depends on a host of factors that include the binding energy of intermediate adsorbates, the nature of the solvent and how well the catalyst solution interface handles reactants and products (e.g. stiffness of the electrochemical double layer).…”
