F, N neutralizing effect induced Co-P-O cleaving endows CoP nanosheets with superior HER and OER performances

Coupled MoO3−x@CoP heterostructure as a pH-universal electrode for hydrogen generation at a high current density

“…2a. For CoP/NF, the peaks located at 782 eV and 798 eV were attributed to the signal of Co 2+ , whereas the peaks located at 778.6 eV and 793.7 eV could be ascribed to the characteristic peak of Co-P. 42 In comparison, the MoO 3− x @CoP sample showed similar signals of Co 2+ and Co-P peaks (except for the different peak intensity). A lower peak ratio of Co-P/Co 2+ was observed for MoO 3− x @CoP, which indicated the interaction between the heterostructure of MoO 3− x and CoP.…”

Heterointerface engineering constructs microenvironment enhancing catalytic kinetics of Fe/Ni oxyhydroxide@FeNi alloy for overall water splitting

“…This is because of the greater electrodeposition NiFe layer coated on NiFe alloys, which ultimately slightly reduces the ECSA; similar phenomena have been reported previously in the literature 6,29,30 Turnover frequency (TOF) is used to measure differences in intrinsic activity in FeNi composites with different molar ratios. [31][32][33][34] The calculated TOF value of FeNi-(1 : 1) O x (OH) y was up to 0.2157 s À1 at an overpotential of 350 mV, which is higher than that of FeNi-(1 : 3) O x (OH) y (0.15687 s À1 ) or FeNi-(3 : 1) O x (OH) y (0.13585 s À1 ) (Fig. 4e).…”

Tunable d-band center of a NiFeMo alloy with enlarged lattice strain enhancing the intrinsic catalytic activity for overall water-splitting

“…Hydrogen is considered an ideal alternative fuel for the future. [2][3][4] Electrochemical water decomposition is an extremely promising technology, and converts H 2 into electrical energy in the transition away from polluting fossil fuel energy. During the electrolysis reaction of water, hydrogen is generated at the cathode surface and oxygen is generated at the anode surface.…”
