An electrochemical study of carbon dioxide electroreduction on gold-based nanoparticle catalysts
Lates, V.; Falch, A.; Jordaan, A.; Peach, R.; Kriek, R.J. (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 charge density and the theory for calculating membrane potential for a nano-composite nylon-6,6 nickel phosphate membrane
Arfin, T.; Falch, A.; Kriek, R.J. (RSC, 2012)A new crystalline organic–inorganic nano-composite nylon-6,6 nickel phosphate membrane was synthesised subsequent to which (a) the physico-chemical characteristics of the membrane were evaluated employing FTIR, SEM, EDX, ... -
Thermally stable Pt/Ti mesh catalyst for catalytic hydrogen combustion
Du Preez, S.P.; Sekoai, P.T.; Bessarabov, D.G.; Falch, A.; Jones, D.R. (Elsevier, 2020)In this study, platinum (Pt) supported on titanium (Ti) mesh catalysts for catalytic hydrogen combustion were prepared by depositing Pt as a thin-layer on metallic or calcined Ti mesh. The Pt thin-layer could be stabilized ...
