H2 production through electro-oxidation of SO2: identifying the fundamental limitations
Kriek, Roelof J.; Rossmeisl, Jan; Siahrostami, Samira; Björketun, Márten E. (RSC, 2014)Sulphur dioxide (SO2), a known industrial pollutant and pulmonary irritant, is emitted to the atmosphere in excess of 120 Mt per annum. Great strides have been taken to reduce SO2 emissions, but with the growth of ... -
Ionic conductivity of alkali halides across a polyaniline-zirconium (iv)-arsenate membrane
Arfin, Tanvir; Kriek, Roelof J.; Bushra, Rani (CEE, 2013)In continuation to our previous work with composite polyaniline-zirconium (IV)-arsenate (PZA), we further extended with the conductivity measurements in this report. All the calculations reported in here were extracted ... -
Laser induced H2 production employing Pt-TiO2 photocatalysts
Falch, Anzel; Kriek, Roelof J. (Elsevier, 2013)The photocatalytic production of hydrogen from water as well as from an aqueous methanol solution employing pre-treated TiO2 and various Pt-TiO2 photocatalysts was studied by using an Nd:YAG laser as irradiation source. ... -
NiSe-Ni3Se2/multiwalled carbon nanotube composites as efficient electrocatalysts for the oxygen evolution reaction in alkaline media
Oyetade, Oluwaseun A.; Kriek, Roelof J. (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 ... -
A study of the thermal and AC impedance properties of N-phenyldithiocarbamate complexes of Zn(II)
Onwudiwe, Damian C.; Arfin, Tanvir; Strydom, Christien A.; Kriek, Roelof J. (Elsevier, 2013)Zinc (II) complexes of phenyl dithiocarbamate and para-methylphenyl dithiocarbamate ligands, represented as [Zn(S2CNHPh)2] and [Zn(S2CNHp-MePh)2], have been synthesized and characterized. The thermal properties and the ... -
Synthesis, spectroscopic characterization and behavior of AC impedance spectroscopy of Cd(II) bis(N-para-methylphenyldithiocarbamate)
Onwudiwe, Damian C.; Arfin, Tanvir; Strydom, Christien A.; Kriek, Roelof J. (Elsevier, 2013)A new dithiocarbamate ligand, para-methylphenyl dithiocarbamate (L), has been synthesized at room temperature. The ligand was reacted with a cadmium salt to give bis(N-para-methylphenyl dithiocarbamate) Cd(II) (CdL2). ...
