Effect of H2S on SO2-depolarised water electrolysis
(Elsevier, 2015)The performance of a PEM SO2 electrolyser, used for the production of H2 gas and liquid H2SO4, was evaluated when the feed was contaminated with hydrogen sulfide. Transient voltage response at constant current density and ... -
An electrochemical study of carbon dioxide electroreduction on gold-based nanoparticle catalysts
(Elsevier, 2014)We report here on an electrochemical study of carbon dioxide electroreduction (CO2ER) employing electrochemical impedance spectroscopy (EIS) and a rotating ring-disk electrode (RRDE) on different gold based catalysts, ... -
Evaluation of MEA manufacturing parameters using EIS for SO2 electrolysis
(Elsevier, 2014)Membrane electrode assembly (MEA) manufacturing parameters such as hot pressing pressure and pressing time were investigated for the use in a SO2 electrolyser. The SO2 electrolysis was optimised in terms of cell temperature, ... -
Evaluation of process parameters and membranes for SO2 electrolysis
(North-West University, 2015)The environmentally unsafe by-products (CO2, H2S, NOx and SO2 for example) of using carbon-based fuels for energy generation have paved the way for research on cleaner, renewable and possibly cheaper alternative energy ... -
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 ... -
Investigation of the adsorption characteristics of some selected sulphonamide derivatives as corrosion inhibitors at mild steel/hydrochloric acid interface: experimental, quantum chemical and QSAR studies
(Elsevier, 2016)Five sulphonamides derivatives namely, sulphanilamide (SNA), sulphamethoxazole (SMX), sulphadimethoxine (SDM), sulphisoxazole (SSZ), and sulphamethizole (SMZ) have been selected as corrosion inhibitors for mild steel in ...
