Gökçel, Zekerya Dursun, Yusuf Dilgin] A new approach is described for the photoelectrocatalytic oxidation of Reduced ß-Nicotinamide Adenine Dinucleotide (NADH). It is based on a glassy carbon electrode (GCE) modified with a film of poly-Neutral Red (poly-NR) that is obtained by electropolymerization. Electrochemical measurements revealed that the modified electrode displays electrocatalytic and photo-electrocatalytic activity towards oxidation of NADH. If irradiated with a 250-W halogen lamp, the electrode yields a strongly increased electrocatalytic current compared to the current without irradiation. Amperometric and photo-amperometric detection of NADH was performed at +150mV vs. Ag/AgCl/KClsat and the currents obtained are linearly related to the concentration of NADH. Linear calibration plots are obtained in the concentration range from 1.0μM to 1.0mM for both methods. However, the slope of the current-NADH concentration curve of the photo-electrocatalytic procedure was 2-times better than that obtained without irradiation. Figure A poly-Neutral Red modified glassy carbon electrode (poly-NR/GCE) was prepared by electropolymerization process. This modified electrode displays electrocatalytic and also photoelectrocatalytic activity towards oxidation of NADH. Compared with electrocatalytic oxidation of NADH, the current response was increased about 2.0 times in the photoelectrocatalytic oxidation process.
