Electrochemical Evaluation of Ni-Mo Electrodes Obtained by Mechanical Alloying

Determination of kinetic parameters for the hydrogen evolution reaction on the electrodeposited Ni–MoO2 composite coating in alkaline solution

“…Jakšić [9] showed that the alloying of Ni and Mo could lead to substantial improvement of the catalytic activity for the HER. The kinetics and mechanism of the HER in alkaline solution were investigated on Ni-Mo based alloys prepared metallurgically [10,11], deposited by vacuum plasma spraying [7,12] or pressed and heated [7] with subsequent leaching of active components, or obtained by mechanical alloying [13], but most studies were focused on NiMo alloys electrodeposited under various operating conditions [4,[14][15][16][17][18][19][20][21][22][23][24][25][26][27][28]. Lowering of the overpotential for the HER observed with the electrodeposited alloys was principally attributed to an increase in real surface area.…”

First‐principles study of surface segregation in bimetallic Ni3M (M = Mo, Co, Fe) alloys with chemisorbed atomic oxygen

“…In particular, nickel‐based alloys have been found to be good catalysts for diverse reactions including aqueous‐phase reforming of oxygenated hydrocarbons , the synthesis gas reactions , propane reforming , and so forth. In the context of the hydrogen‐evolution reaction (HER), extensive experimental studies showed that the addition of a small amount of transition metal (M), such as Mo , Co , or Fe , to a Ni electrode could significantly promote its HER electro‐catalytic activity of the nickel‐based bimetallic electrode. This is because alloying Ni catalyst with a transition metal can improve the bond strength of the bimetallic catalyst, which consequently enhances the hydrogen‐evolution reaction .…”

Ni50Mo40Ti10 alloy prepared by mechanical alloying as electroactive material for hydrogen evolution reaction

“…Numerous materials for this purpose have been proposed and examined. Among these materials, NiMo alloys are known to give a significant decrease in the hydrogen evolution overpotential . Also, some NiTi alloys exhibit enhanced electrocatalytic activity toward the hydrogen evolution reaction (HER) .…”

“…Also, some NiTi alloys exhibit enhanced electrocatalytic activity toward the hydrogen evolution reaction (HER) . Numerous publications have described the properties of these materials, and their authors assigned the improvement of the electrochemical activity both to the increase in the active surface area of the electrode and to the intrinsic activity of the material . The increase in the intrinsic activity results from the synergetic effect of components of the material and could be related to its structural, chemical or electronic properties, e.g.…”
