Spiral nanoporous gold electrode: A simple strategy for enhancing the attenuated-total-reflection infrared spectroelectrochemical sensitivity

• A new designed ATR-IR-SEC cell was used for spectroelectrochemical analysis.
• A conventional three-electrode cell was used.
• A spiral nanoporous gold electrode was used to enhance the sensitivity.
• Ferricyanide and two antioxidants were determined using this new cell.

In this study, a conventional three-electrode cell was used for the attenuated-total-reflection infrared spectroelectrochemical (ATR-IR-SEC) detection but an innovative spiral nanoporous gold electrode (SNPGE), which was prepared by a one-pot single-step method, was employed as the working electrode to enhance the spectroelectrochemical sensitivity. Potassium ferricyanide (K3Fe(CN)6) was used as a model compound for evaluating the performance of the ATR-IR-SEC cell and two antioxidants, gallic acid and n-propyl gallate, were determined using this device to know the potential applicability.
