Cauliflower-like NiFe alloys anchored on a flake iron nickel carbonate hydroxide heterostructure towards superior overall water and urea electrolysis

Abstract

Exploring efficient, stable and multifunction earth-rich electrocatalysts is vital for hydrogen generation. Hence, an efficient heterostructure consisting of cauliflower-like NiFe alloys anchored on flake iron nickel carbonate hydroxide which supported...

Electrodeposited Ni–Fe alloy as a cost-effective material for harnessing hydrogen via the oxygen evolution and urea oxidation reactions

“…29 Binary metals and their alloying effect may change the adsorption energy of the intermediate products and adjust the position of the d-band center to improve the intrinsic activity of the catalysts. 30 Studies have shown that surface modified or functionalized Ni substrates with various defects through physical and chemical approaches exhibit enhanced electron transfer kinetics, without having surface poisoning, augmenting the oxygen/urea oxidation reaction. 31,32…”

Electrospinning construction of a Fe–Ni-based multicomponent hybrid as synergistic electrocatalyst for water electrolysis

“…56 Also, transition metal alloys can improve the electronic structure of the catalyst surface and enhance the catalytic activity and stability. 57 In addition, carbon materials are widely used as important compositions to improve the conductivity of the electrocatalysts in a variety of electrochemical conversion devices. Among various carbon-based materials, carbon nanobers (CNFs) have generated great interest in eminent research due to their intrinsic advantages such as lightweight, high electrical conductivity, and stability.…”

“…56 Also, transition metal alloys can improve the electronic structure of the catalyst surface and enhance the catalytic activity and stability. 57 However, most catalysts were limited by single functionality or low activity, therefore, it is expected to construct multifunctional catalysts with high activities by composite multiple components.…”
