Electrochemiluminescence of Bare Glassy Carbon with Benzoyl Peroxide as the Coreactant in N,N-Dimethylformamide

The electrochemiluminescence (ECL) properties of many carbon materials have been reported with glassy carbon (GC), Pt, Au or indium tin oxide (ITO) as the working electrode (WE). As one type of carbon materials, GC itself can generate ECL signal. Some research groups have already noticed the ECL signal from GC WE and reported the results of GC WE with respect to their luminophores. However, comprehensive analyses of ECL properties of GC WE are rare. Herein, the ECL properties of GC WE in organic electrolyte with benzoyl peroxide as the coreactant are reported. Our results are of great importance to distinguish the true ECL data of luminophores from that of GC. Sky-blue light was generated in the electrochemiluminescence process of bare glassy carbon working electrode with benzoyl peroxide as the coreactant.
