An advanced and highly efficient Ce assisted NiFe-LDH electrocatalyst for overall water splitting

Abstract

A room-temperature synthesized NiFeCe2 electrocatalyst delivered a current density of 10 mA cm−2 at a cell voltage of 1.59 V when used as the electrolyzer.

A Review of Transition Metal Oxygen-Evolving Catalysts Decorated by Cerium-Based Materials: Current Status and Future Prospects

“…The main synthesis strategies focus on solvothermal [50][51][52] and electrodeposition method. 53,54 Electrodeposition method is often used to deposit CeBM on parent LDHs. As an example, FeOOH/CeO 2 heterolayered nanotubes (HLNTs) was obtained by Li and coworkers via electrodeposition at a specific current density and temperature (Figure 2a).…”

Two-phase synthesis of Fe doped cerium phosphate ultra-fine nanocrystals for efficient oxygen evolution

“…Developing active OER electrocatalysts that can accelerate O-H bond fracture and O-O bond formation is essential but remains a huge challenge. [5][6][7] Current industrial level OER electrocatalysts are highly dependent on precious metal catalysts, mainly iridium (Ir) and ruthenium (Ru)-based catalysts; [8][9][10] however, the large-scale commercialization of precious metalbased OER electrocatalysts is greatly hindered by their high cost, low crustal reserves and relatively poor stability. 11,[12][13][14][15][16][17] Therefore, it is very important to develop efficient, economical and stable non-precious metal-based electrocatalysts to make the OER a viable and scalable energy storage technology.…”

Enhancing water splitting via weakening H2 and O2 adsorption on NiCo-LDH@CdS due to interstitial nitrogen doping: A close look at the mechanism of electron transfer

“…What is more, LDH microcrystals can be employed as monolayer nanosheets in fabricating electrocatalysts [30,31]. LDHs are made up of transition metal cations, especially Ti, Co, Fe, Ni, Mg, and Zn and are extensively employed in electrocatalytic reactions, particularly for HER and OER [32][33][34]. LDH-based water splitting catalysts previously reported in the literature include NiFe-LDH/GO [35], NiFe-LDH/CQD [36], CoMn-LDH [37], ZnCo-LDH [38], ZnO@CoNi-LDH [39], Mo-NiFe-LDH [40], Co 9 S 8 @NiCo LDH [41], and NiV LDHs [42].…”
