[Ni/AlCl]-based hydrotalcite electrodes as amperometric sensors: preparation and electrochemical study

Amperometric Sensors Based on Synthetic Hydrotalcites and Their Application for Ethanol Detection in Beer

“…Ni/Al-X HT modified electrodes have been extensively studied by our group [14] as amperometric sensors for the determination of alcohols and sugars. All the analytes, which were electrochemically oxidized at those electrodes, have been considered again in this work in order to exploit the electrocatalytic activity of Co/Al-NO 3 modified electrodes.…”

Clay Modified Electrodes: Present Applications and Prospects

“…However, every electrode required the individual calibration plot due to difficult preparing the reproducible clay coatings [104]. Different kinds of [Ni/AlCl]-based electrodes have been constructed in order to find amperometric sensors with the best performance in terms of reproducibility of the signal, chemical and mechanical stability, lifetime, and simple regenerability of the surface [105]. The amperometric sensors have been tested on methanol, mannitol and glucose substrates, for all the electrodes the currents were very low.…”

Electrochemical behavior of phenol in alkaline media at hydrotalcite-like clay/anionic surfactants/glassy carbon modified electrode

“…In the last years many researches has been done related to the feasibility of using inorganic materials, such as zeolites [17][18][19], clays and microporous materials [20][21][22][23][24], to modify the electrode surface, preconcentrate and detect the species. In general, clays exhibit good stability, show high temperature tolerance, and have extraordinary oxidative properties.…”
