Rock salt type NiCo2O3 supported on ordered mesoporous carbon as a highly efficient electrocatalyst for oxygen evolution reaction

Nickel foam and stainless steel mesh as electrocatalysts for hydrogen evolution reaction, oxygen evolution reaction and overall water splitting in alkaline media

“…2 In recent years, much effort has been made on the developing of inexpensive electrocatalysts for HER, OER and overall water splitting based on earth-abundant transition metals. For example, a large amount of transition metal oxides, [9][10][11][12][13][14] hydroxides, [15][16][17][18] chalcogenides, [19][20][21][22] phosphides, [23][24][25][26][27] suldes [28][29][30][31][32] and carbides 33,34 have been explored as efficient and potential HER, [19][20][21][22][23][24][25][26][27][28][29][30]32,[25][26][27][28][29][30][31]33 and overall water splitting electrocatalysts 25,…”

Alkaline Water Oxidation Using a Bimetallic Phospho‐Boride Electrocatalyst

“…[1,2] In the form of oxides/hydroxides/oxy-hydroxides, metals such as Ni, Co, and Fe have shown satisfactory performances in alkaline electrolytes. [3][4][5][6][7] Layered double hydroxides (LDHs) of these transition metals have even surpassed the most active and stable IrO 2 and RuO 2 catalysts, largely due to their higher surface areas, but in turn suffer from poor conductivity. [8,9] In addition to these, compounds of transition metals in the form of phosphides, [10,11] sulfides, [12,13] borides, [14,15] selenides, [16,17] nitrides, [18,19] and carbides [20,21] have emerged as promising low-cost alternatives.…”

Coordination environment evolution of Co(ii) during dehydration and re-crystallization processes of KCoPO4·H2O towards enhanced electrocatalytic oxygen evolution reaction

“…[6][7][8] Therefore, efficient electrocatalysts with high activity and high stability are desirable to realize its practical application. 9,10 To date, noblemetal oxides, such as RuO 2 and IrO 2 are considered to be the state-of-the-art electrocatalysts for the OER, 11,12 but their high cost, limited reserves and stability problem prevent their largescale industrial application. 13 Currently, extensive research efforts have been focused towards the development of costeffective transition-metal based OER catalysts.…”
