The conversion of carbon dioxide into value-added products is progressively gaining momentum. Several strategies have been used to develop technologies that reduce the net emissions CO2. utilisation CO2 could either contribute recycling. In this paper, transformation was investigated in a coelectrolysis cell constituted solid polymer electrolyte, carbon-supported CuO-Ag composite cathode and Ni...

Electrochemical systems are considered for which the concentration of ions in solution is low, and therefore there is an electric field which extends deep into solution away from the electrode surface. Finite difference methods are used to model a potential step chronoamperometry experiment at a microhemisphere electrode. Concentration profiles, potential profiles, and current-time curves are p...

The electrochemical properties of the (PCP)Rh(H2) (1-H2, PCP 1⁄4 k-C6H3e2,6-(CH2P(Bu2)) complex was examined by cyclic voltammetry in acetonitrile (MeCN), dimethylsulfoxide (DMSO) and 1,2difluorobenzene (1,2-DFB). Upon oxidation in weakly or non-coordinating media such as 0.05 M NaBAr24 in 1,2-difluorobenzene, simple one electron oxidation to [(PCP)RhII(H2)]þ is observed. Conversely, in coordin...

Many quinolones, substituted quinolines and thiones are well known for their biological activity. The redox characteristics of such biological substances may provide valuable information about the redox behaviour in living systems. The present paper is aimed at carrying out a methodical cyclic voltammetric investigation of the peak potential values of 4-methyl/phenyl -3vinyl quinoline-2(1H) one...

The voltammetric oxidation of all deoxyribonucleic acid (DNA) monophosphate nucleotides is investigated for the first time over a wide pH range by differential pulse voltammetry with a glassy carbon electrode. Experimental conditions such as the electrode size, supporting electrolyte composition, and pH were optimized to obtain the best peak potential separation and higher currents. This enable...

The electroreduction of the fullerene Cm in 1,2-dichlorobenzene (ODCB) and benzonitrile (PhCN) at a Pt electrode was studied by using scanning electrochemical microscopy and fast scan cyclic voltammetry. The former technique was employed for steady-state measurements in a thin-layer cell formed by an ultramicroelectrode tip and mercury pool substrate. The standard heterogeneous rate constants f...
