Application of Sm0.8Sr0.2Fe1-xCoxO3-δ (x = 0.2, 0.5, 0.8) perovskite for the oxygen evolution reaction in alkaline media
(Springer, 2019)A new type of perovskite, i.e. Sm0.8Sr0.2Fe0.8Co0.2O3-δ (SSFC1), Sm0.8Sr0.2Fe0.5Co0.5O3-δ (SSFC2), and Sm0.8Sr0.2Fe0.2Co0.8O3-δ (SSFC3) were (i) synthesised by employing a sol gel method with subsequent calcination at 1000 ... -
Development of efficient membrane electrode assembly for low cost hydrogen production by anion exchange membrane electrolysis
(Elsevier, 2017)Electrochemical production of hydrogen from water using anion exchange membranes (AEMs) can be achieved with non-noble catalysts, other than traditional proton exchange membranes that use platinum group metals. Using ... -
Hydrogen production by water electrolysis with an ultrathin anion-exchange membrane (AEM)
(ESG, 2018)A new ultrathin anion exchange membrane (AEM) is proposed for low cost AEM electrolysis. The advantages that thin membranes offer include reduced mass transport resistance and ohmic resistance. A membrane electrode ... -
Investigating reactive sputtered IrxNiyOz electrocatalysts for the oxygen evolution reaction
(North-West University (South Africa)North-West University, 2020)Alkaline water electrolysis (AWE) is a promising, simple and environmentally friendly technology, when coupled with renewable energy sources (e.g. wind and solar), to produce high purity hydrogen gas for clean energy ... -
NiSe-Ni3Se2/multiwalled carbon nanotube composites as efficient electrocatalysts for the oxygen evolution reaction in alkaline media
(Springer, 2020)The development of effective electrocatalysts for the oxygen evolution reaction (OER) is of great importance to combat energy-related concerns in the environment. Herein, we report a one-step solvothermal method employed ... -
Photocharged water splitting employing a Nickel(II) Tellurium Oxide (Photo)anode in alkaline medium
(ACS, 2019)Nickel-based oxides and (oxy)hydroxides are known to be electrocatalytically active for the oxygen evolution reaction (OER) in an alkaline medium. However, the aforementioned materials would be more auspicious, especially ... -
Photocharging of europium(III) tellurium oxide as a photoelectrocatalyst
(ACS, 2019)This work reveals that Eu2TeO6, as a photoelectrocatalyst, exhibits a sustained photocharging effect that results in an enhanced and “sustained” dark current (subsequent to the termination of illumination), which is greater ... -
Screening of Pt/Ni bimetallic electrocatalysts using DFT calculations
(North-West University (South Africa), 2021-06)Clean, renewable energy could be produced from the electrocatalytic splitting and recombination of water in electrolysers and fuel cells, called electrochemical devices. However, the development of these electrochemical ... -
Silver/nickel oxide (Ag/NiO) nanocomposites produced via a citrate sol-gel route as electrocatalyst for the Oxygen Evolution Reaction (OER) in alkaline medium
(Springer, 2018)A series of Ag/NiO nanocomposite electrocatalysts, with a general molecular formula of Ag x Ni1 − xO, was synthesised employing the citrate sol-gel route and tested for the oxygen evolution reaction (OER) in 0.1 M KOH ... -
Synthesis and evaluation of (NiZnxCry)O electrocatalysts for the oxygen evolution reaction
(North-West University (South Africa), 2021)Stored energy, as a result of the conversion of renewable resources has resulted in extensive research and development efforts towards water electrolysis. Alkaline water electrolysis, in combination with renewable energy ...
