3D self-supporting nickel sponge substrate derived CoFeLDH/SN as an efficient bifunctional electrocatalyst for overall water splitting

Transition metal-based electrocatalysts for alkaline overall water splitting: advancements, challenges, and perspectives

“…SEM showed the core–shell nanostructure, which is advantageous for increasing the catalyst's surface area and exposing more active sites. The excellent conductivity of the Ni@NiFe LDH is also reflected in its low charge transfer resistance ( R ct ).Zhang et al 108 hydrothermally created a three-dimensional (3D) self-supporting nickel sponge (SN) with nano-Ni synapses and then deposited 2D CoFeLDH nanosheets on the nickel sponge using the electrodeposition approach. CoFeLDH was also deposited on a NF substrate for comparison using the same deposition procedure.…”

Constructing interfacial structure of Mo5N6/Ni3N/Ni/NF for efficient and stable electrocatalytic hydrogen evolution under alkaline conditions

“…17 Over the past few decades, a lot of efforts have been devoted to the research of nonprecious catalysts intended to replace Pt-based ones. [18][19][20][21] In these studies, transition metal nitrides (TMNs) have attracted extensive attention due to their excellent electrical conductivity, electrocatalytic activity, and mechanical strength. 22,23 In particular, the typical TMNs catalyst, e.g., metallic nickel nitride (Ni 3 N), has received extensive attention.…”
