Enhanced Hydrogen Evolution Activity of Ni[MoS2] Hybrids in Alkaline Electrolyte

MoS2 Effect on Nickel Electrochemical Activation: An Atomistic/Experimental Approach

“…It can be seen that E r values are consistent to that observed in the OP. The different catalysts have variable j 0 values, the highest being found in the NMS catalyst, where MoS 2 is exposed, which has already been reported in the literature …”

“…The different catalysts have variable j 0 values, the highest being found in the NMS catalyst, where MoS 2 is exposed, which has already been reported in the literature. 11 Chronoamperometry experiments were performed in order to carry out short aging of the catalysts using pulses of −1.5 V (vs SCE) for 4 h in 1 M KOH. The chronoamperometric profiles obtained for the three characterized catalysts are shown in Figure 4b.…”

“…5,8−10 In a previous article, we demonstrated that the interaction between a conventional nickel layer electrodeposited from a Watts electrodeposition bath and MoS 2 allows us to considerably increase the catalytic activity toward the electrochemical generation of hydrogen, controlling certain parameters of synthesis. 11 In that work, the synthesis of a Ni−MoS 2 composite by direct electrodeposition was performed by modifying a conventional Ni Watts plating bath by the addition of MoS 2 particles with a 3D structure. Electrodeposition was carried out for 45 dm −2 .…”
