Electrodeposited Ni dendrites with high activity and durability for hydrogen evolution reaction in alkaline water electrolysis

Facile Synthesis of M-MOF-74 (M=Co, Ni, Zn) and its Application as an ElectroCatalyst for Electrochemical CO2 Conversion and H2 Production

“…Given that the hydrogen evolution reaction (E o = 0.0 V RHE ) precedes the reduction of CO 2 (E o = -0.11 V RHE ), it is more probable that the initial current response was due to the hydrogen evolution. It is known that Co and Ni are efficient hydrogen evolution catalysts, and they have been intensively investigated [39][40][41]. Hence, the smaller overpotentials for Co-and Ni-MOF-74 compared to Zn-MOF-74 were ascribed to their superior catalytic activities toward hydrogen evolution.…”

High-activity electrodeposited NiW catalysts for hydrogen evolution in alkaline water electrolysis

“…Ni has been known as a prospective HER catalyst material [9], and further enhancement of its activity has been investigated by forming NiM alloys (M = Fe, Co, Cu, Mo, W, etc.) [10][11][12][13][14][15][16][17][18], synthesizing Ni composites (e.g., NiP x and NiS x ) [19][20][21][22][23], and controlling Ni nanostructures [24][25][26]. The origin of the alloys' high activities is typically explained by a changed lattice parameter and electronic structure of Ni, as affected by the addition of varied amounts of M into the Ni [11,12].…”

Electrospun nickel-decorated carbon nanofiber membranes as efficient electrocatalysts for hydrogen evolution reaction

“…Ni is one kind of transition metals, which has potential applications in many fields, such as lithium ion batteries [12], magnetic materials [13], and catalysis [14]. Moreover, Ni has been considered as a good electrocatalyst candidate for HER due to its high abundance, low cost and relatively high electrocatalytic activity [15,16]. However, the tendency of severe nanoparticle aggregation will decrease the specific surface area, yielding an inferior electrochemical activity.…”
