Adsorption at non-metal electrodes

As can be seen from Fig. 48, four negative (product) features appeared in the chosen spectral range at potentials cathodic of - 1100 mV vs. Ag/Ag+ (i.e. at 2017.5,2041.4,2065, and 2090 cm 1). These features were only observed 

In 1985, Datta et al. [96] reported in-situ FTIR studies of adsorption at a glassy carbon electrode. The paper was a preliminary report and the authors concluded that phosphate and sulphate are adsorbed at a glassy carbon electrode whilst perchlorate was apparently not, in keeping with the generally held view. 

SNIFTIRS is an extremely versatile technique, especially when it is realised that virtually any electrode may be employed providing it is IR reflective, e.g. metals, doped semiconductors, basal plane and edge pyrolytic graphite, and glassy carbon, etc. As yet, its applications have only been touched upon, but it is expected that the technique is, and will continue to be, an increasingly powerful tool in the hands of the electrochemist.
