Dependency on chloride concentration and ‘in-sphere’ oxidation of H2O for the effective TiO2-photocatalysed electron transfer from H2O to [PdCln(H2O)4−n]2−n (n = 0–4) in the absence of an added sacrificial reducing agent
Kriek, Roelof Jacobus; Mahlamvana, Foster (Elsevier, 2012)The photocatalytic reduction trends of palladium chloride aqua complexes, [PdCln(H2O)4−n]2−n (n = 0–4), have been investigated employing titanium dioxide (TiO2) as photocatalyst in the absence of an added sacrificial ... -
The effect of sputtered Pt40Pd57Al3 thin film thickness on SO2(aq) electro-oxidation
Falch, Anzel; Kriek, Roelof Jacobus; Geldenhuys, Zarco; Shnier, Adam; Wamwangi, Daniel (Springer, 2019)The influence of sputtered Pt40Pd57Al3 thin films of varying thickness, in the as-deposited (AD) and annealed (AN) state, was investigated for the electro-oxidation of aqueous SO2. From physical characterisation (scanning ... -
An electrochemical and theoretical comparison of ionic transport through a polystyrene based titanium-vanadium (1:2) phosphate membrane
Arfin, Tanvir; Kriek, Roelof Jacobus; Jabeen, Fakhra (Elsevier, 2011)Ionic potentials were measured across polystyrene based titanium–vanadium (1:2) phosphate membranes with 1:1 electrolytes at different concentrations. These observed values are found to compare well with membrane potentials ... -
New insights into the halide-related reactions on platinum surfaces : an electrochemical investigation
Mogwase, Boitumelo Mmamopedi Sarah (North-West University (South Africa). Potchefstroom Campus, 2019)The results of an electrochemical investigation of polycrystalline platinum are presented. The aim of the study was the elucidation of aspects of the electrochemistry of polycrystalline platinum in 0.5 M sulphuric acid ...
