High catalytic performance of nano-flowered Mg-doped NiCo layered double hydroxides for the oxygen evolution reaction

Abstract

Layered double hydroxides (LDH) is one of the ideal functional materials for oxygen evolution reaction (OER) because of its special configuration and good electrochemical activity. Incorporating different divalent and trivalent...

Controlled growth of Sb2S3 nanorods on phosphorus doped reduced graphene oxide for enhanced overall water splitting

“…6–8 Noble metal-based materials, such as Pt/C, Pd, RuO 2 and IrO 2 , are known to be the most effective overall water splitting electrocatalysts due to their relatively lower overpotential and high reaction rates. 9,10 However, due to the high cost and scarcity of these metals, they are replaced by transition metal-based catalysts, their derivatives in numerous oxidation states, which show similar activity. 11–18…”

“…[6][7][8] Noble metal-based materials, such as Pt/C, Pd, RuO 2 and IrO 2 , are known to be the most effective overall water splitting electrocatalysts due to their relatively lower overpotential and high reaction rates. 9,10 However, due to the high cost and scarcity of these metals, they are replaced by transition metal-based catalysts, their derivatives in numerous oxidation states, which show similar activity. [11][12][13][14][15][16][17][18] Recent research has focused on doping pristine graphene nanosheets with various heteroatoms such as nitrogen (N), boron (B), phosphor (P), sulfur (S), fluorine (F) and oxygen (O).…”

Defect-rich carbon-coated nickel–cobalt alloy nanoparticles enhanced the OER catalytic activity through surface reconstruction

“…7 Therefore, the development of abundant and low-cost non-precious metal catalysts is the key to achieving the industrial application of electrocatalytic decomposition of water reactions. 8 Among various catalysts, nickel-cobalt-based materials are widely used in multiphase catalysis 9 due to their advantages of environmental friendliness, 10 abundant reserves, low cost, 11 and multivalent state. 12 However, limited by the limitations of the ability of different oxygen intermediates in OER optimization of a single metal component, their electrocatalytic activity needs to be further improved.…”
