摘　　要：Mediated electrochemistry of dimethyl sulfoxide reductase from Rhodobacter capsulatus (DMSOR) which is immobilized on a bare glassy carbon (GC) electrode and a carbon nanotube (CNT)-modified GC electrode was studied using the Co complex (trans-6,13-dimethyl-1,4,8,11-tetraazacyclotetradecane-6,13-diamine)cobalt(III) ([Co(trans-diammac)] +) as a mediator.The cyclic voltammograms of different electrodes were carried out at different substrate (DMSO) concentrations.The results demonstrated that the catalytic current was increased by employing CNT as a promoter.Mediated electrochemistry of dimethyl sulfoxide reductase from Rhodobacter capsulatus (DMSOR) which is immobilized on a bare glassy carbon (GC) electrode and a carbon nanotube (CNT)-modified GC electrode was studied using the Co complex (trans-6,13-dimethyl-1,4,8,11-tetraazacyclotetradecane-6,13-diamine)cobalt(III) ([Co(trans-diammac)] +) as a mediator.The cyclic voltammograms of different electrodes were carried out at different substrate (DMSO) concentrations.The results demonstrated that the catalytic current was increased by employing CNT as a promoter.
