Co-sputtered PtxPdyAlz thin film electrocatalysts for the production of hydrogen via SO2(aq) electro-oxidation
(Springer, 2016)A co-sputtered PtxPdyAlz ternary system was investigated for potential use as anode catalyst for the electro-oxidation of aqueous sulphur dioxide (SO2), a key reaction in the hybrid sulphur (HyS) process for splitting water ... -
Comparative study of anion exchange membranes for low-cost water electrolysis
(Elsevier, 2020)Various anion-exchange membranes (AEMs) were studied in the electrolysis cell using the non-precious metal-based catalysts showing the good potential of selected AEMs in low-cost water electrolysis application. The 0.1–1 ... -
Current status, research trends, and challenges in water electrolysis science and technology
(Elsevier, 2020)Water electrolysis has various industrial applications. Over the past years, interest in water electrolysis technologies has increased largely due to the renaissance of the nuclear-hydrogen energy concept and also the ... -
Electrocatalytic process for ammonia electrolysis: a remediation technique with hydrogen co-generation
(ESG, 2016)Alkaline ammonia electrocatalysis offers a favorable technique for hydrogen generation and simultaneous conservation of environmental sustainability. In this work, the electrooxidation of ammonia on platinum-Iridium (Pt-Ir) ... -
An evaluation of a microchannel reactor for the production of hydrogen from formic acid
(North-West University, 2018)This dissertation evaluates the performance of a microchannel reactor for the decomposition of vaporised formic acid as a promising technology for the production of hydrogen for proton exchange membrane fuel cell applications. ... -
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 from a rectangular horizontal filter press Divergent Electrode-Flow-Through (DEFT™) alkaline electrolysis stack
(Elsevier, 2017)A membraneless Divergent Electrode-Flow-Through (DEFT™) alkaline electrolyser, for unlocking profitable hydrogen production by combining a simplistic, inexpensive, modular and durable design, capable of overcoming existing ... -
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 ... -
Investigating sputtered thin film Pt-containing electrocatalysts for SO2(aq) electro-oxidation
(North-West University (South Africa) , Potchefstroom Campus, 2016)Environmental concerns, social, economic and political pressure, and new technologies are the main factors driving change in energy systems around the globe. Human life and development are inevitably dependent on energy ...
