Electroreduction of nitromethane in aqueous solution. A surface indifferent electrocatalytic reaction

Article Abstract:

A study was conducted to show that the electroreduction of nitromethane in aqueous solutions support a mechanism of the heterogeneous ECEEE type on gold electrodes. Nitromethane was reduced in aqueous media in a pH 6 buffer of KH2PO4 using a 24 micron gold microband electrode. Experimental results indicated that the chemical step in the reaction sequence is about a factor of 2 slower in D2O than in water. Findings also showed that nitromethane reduction on gold accommodated an ECEEE mechanism with a heterogeneous chemical step of about 0.1 cm 2(super -1).

Mechanistic aspects of the electrocatalytic oxidative cleavage of 1,2-diols by electrogenerated Pb(IV)

Article Abstract:

Research was conducted to examine the mechanistic aspects of the electrocatalytic oxidative cleavage of 1,2-diols by electrogenerated Pb(IV). Voltammetric data derived by both channel flow cell and rotating disk electrode experiments are examined using numerical simulation. Results reveal the importance of the structural features of the diols in modifying the ligand sphere of the intermediate Pb(IV) metal complex, thereby shifting the sensitive preequilibria for this highly fluxional system.

Electrochemically driven ion insertion processes across liquid/liquid boundaries: neutral versus ionic redox liquids

Article Abstract:

Electrochemical processes in thin film and droplet deposits of THPD and TriHPD have been investigated as a function of the proton concentration in the aqueous electrolyte. Voltammetric and in-situ spectroelectrochemical experiments have been shown that both neutral and ionic redox liquids undergo redox conversion accompanied by ion insertion or expulsion.
