Engineering vanadium phosphide by iron doping as bifunctional electrocatalyst for overall water splitting

Tuning the intrinsic catalytic activities of oxygen-evolution catalysts by doping: a comprehensive review

“…Xiang et al tuned the electronic structure of vanadium phosphide by including Fe into its lattice domain, which demonstrated remarkable OER activity. 189 Among all, the sample with a 1:3 ratio of Fe/V has the highest activity. XPS analysis identifies increased valency of V because of the incorporation of Fe, which optimizes the adsorption of *OH on active sites.…”

Transition‐Metal Phosphides: Activity Origin, Energy‐Related Electrocatalysis Applications, and Synthetic Strategies

“…During the past few years, non‐noble‐metal‐based phosphides, including Fe, Ni, Co, Mo, Cu, W, V, Mn, Zn, Al, etc., have been widely investigated as a low‐cost, high‐active, and long‐life electrocatalyst toward HER. [ 75–80 ] Additionally, on the one hand, there are many reviews about non‐noble‐metal phosphides for HER electrocatalysis. [ 58,81–85 ] On the other hand, the electrocatalytic activity of non‐noble‐metal phosphides are still not comparable to that of the benchmark Pt/C material.…”

Hierarchical NiCo / NiO / NiCo 2 O 4 composite formation by solvothermal reaction as a potential electrode material for hydrogen evolutions and asymmetric supercapacitors

“…4,5 However, those have huge overpotentials for the electrolysis process which are deeply restricted their practical widespread uses. 6,7 On the other hand, the fabrication of electrochemical energy storage devices, including rechargeable batteries, fuel cells, and supercapacitors, has greatly boosted the energy reservoirs for electric vehicles and smart devices. 8 In particular, metal oxides have fascinated more attention as supercapacitor electrodes with the desirable structural features and electrochemical activity.…”

“…14,15 In recent years, transition metal oxides, including NiO, RuO 2 , MnO 2 , Co 3 O 4 , and SnO 2 , were widely inspected as promising electrode materials for electrocatalysis and supercapacitors. 7,16,17 However, high cost, toxicity, low electrical conductivity, and small energy density of the metal oxides significantly limit its large-scale application. In recent times, spinel structured TCo 2 O 4 (T = Mn, Ni, etc.)…”
