“…Although it was inferior to 20 wt% Pt/C, it was comparable to or better than other reported selenide or sulfide electrocatalysts in acidic/alkaline electrolytes (Fig. 5d), such as MoSe 2 -Cu 2 S, 42 MoS 2 /NiS 2 -3, 43 CuSe, 44 CuFe/ NF, 45 Cu@CoFe LDH, 46 Se-doped MoS 2 , 22 Au@MoS 2 , 47 MoSe x S 2−x /Ni, 48 Co 9 S 8 -Ni 3 S 2 -CNTs/NF, 49 and EG/Co 0.85 Se/ NiFeLDH. 50 Electrochemical impedance spectroscopy (EIS) was performed to further examine the HER reaction mechanism.…”

“…In particular, research using two electrodes (anode and cathode) as one catalyst material for overall water splitting can reduce production costs and produce various commercial benets. [16][17][18] One way to apply transition metals and carbon materials to the overall water splitting catalyst is to improve the performance by controlling the energy band gap. The way to adjust the band gap is by doping a transition metal and a carbon material with various kinds of elements (N, P, S, O, or Se).…”

“…49 High hydrophilicity is a critical requirement for OER electrodes, which can improve the contact between an electrode and an electrolyte, resulting in faster charge transfer during water electrolysis. 50 In a dedicated test, water droplets stayed on the NF surface, but quickly penetrated the surfaces of Ni NWS/NF and Fe/Ni NWS/NF (Fig. S5 †), indicating excellent hydrophilicity of the nanowires and nanosheets.…”
