This study was conducted to develop a TiO2–Fe2O3-based electrode supported with carbon and a conductive polymer and to evaluate its performance in the electrochemical detection of paracetamol. The electrode was fabricated using a brush-coating method on a nickel mesh plate with a composition consisting of TiO2–Fe2O3, carbon materials (Vulcan and Binchotan), and a conductive polymer (polyani…
