Synergistic Effects of Co and Fe on the Oxygen Evolution Reaction Activity of LaCoxFe1−xO3

“…These effects have been attributed to the tuning of adsorption energy differences, [8] consequently affecting the potential‐limiting step, as well as to differences in electrical conductivity [9] . Notably, the combination of Fe and Co has shown evidence for improved electrochemical activity in metal oxides, [10–13] in particular in Co and Fe containing spinels, [7,14–18] phosphides, [10,19] borides and nitrides [20–24] …”

“…[9] Notably, the combination of Fe and Co has shown evidence for improved electrochemical activity in metal oxides, [10][11][12][13] in particular in Co and Fe containing spinels, [7,[14][15][16][17][18] phosphides, [10,19] borides and nitrides. [20][21][22][23][24] Perovskites (chemical formula ABO 3 ) represent another interesting class of metal oxides that allows for broad tuning of properties through variation of the A-and B-cations. [25] Several reviews address their activity for the oxygen evolution reaction.…”

Porous FeP supported on 3D nitrogen-doped carbon fibers as efficient electrocatalysts for wide-pH hydrogen evolution

“…In addition, XRD and HRTEM results exhibit a low crystallinity of p-FeP, which is benecial to the HER as previously reported. [29][30][31] XPS analysis shows the existence of Fe-N in p-FeP/NCF/CP, which may also contribute and facilitate the activity of the catalyst. 26,[32][33][34][35][36] Therefore, the 3D network and porous structure of p-FeP/NCF/CP endows its advantages of exposing more active sites for HER, and the low crystallinity and the existence of Fe-N collectively account for its high catalytic activity toward HER.…”

Electrochemically reconstructed high-entropy amorphous FeCoNiCrVB as a highly active oxygen evolution catalyst

“…3 Nowadays, noble metal oxides, such as RuO 2 and IrO 2 , have been used as benchmark OER catalysts, however, their high cost and poor stability limit large-scale applications. 4 Therefore, researchers have evaluated earth-abundant and promising transition-based-alloys and their phosphides, 5 selenides, 6 carbides, 7 and borides 8 for efficient water splitting. In fact, non-oxide catalysts would experience rapid in situ electrochemical transformation and form real OER active sites in alkaline solution.…”
