“…Quite recently, nanostructured Pd has also been demonstrated to be an excellent electrocatalyst for glucose oxidation and for the fabrication of glucose biosensors. [2,[42][43][44][45][46][47][48] However, pure Pd nanomaterials are used in most of these works. For practical applications, Pd-based alloy nanomaterials are more interesting.…”

The synthesis of polyaniline (PANI) containing different carbon nanotubes (CNTs) by in situ electrochemical polymerization is reported in this study. The samples were characterized by scanning electron microscopy. Fourier transform infrared and ultraviolet– visible spectroscopy were used to determine the change in structure of the polymer/CNT composites. Thermogravimetric analysis showed that the composites had better thermal stability than the pure PANI. In addition, the electrochemical measurements such as cyclic voltametric (CV) curves showed that the conductivity of the obtained nanocomposite increased. The results of measuring cyclic voltammetry also showed that the specific capacitance of nanocomposite was much higher than the pure PANI and CNTs. This is due to the fact that the composites consisting of electroactive species and carbon materials with highly specific surface areas are significantly promote the energy density of supercapacitors. Such supercapacitors exhibit simultaneously both double layer capacitance and Faradic pseducapacitance in energy storage.

“…The loss of activity of enzyme limits significantly also the stability of the sensor. However, glucose detection without enzyme via the electro oxidation method exhibits many distinct advantages such as easy and direct electron collection, the possibility of low potential application, superior stability and simple electrode construction [9][10][11][12][13].…”

Approximately global Pd and Pd94Cu6 alloy nano catalysts of average diameter 10.5 and 5.9 nm respectively, have been synthesized hydrothermally by wet chemical reduction and co‐reduction methods without addition of any capping agent. X‐ray diffraction and various microscopic studies are used to characterize the crystal phase and the morphology of the catalysts. Non‐enzymatic amperometric glucose sensors based on these synthesized catalyst materials are tested and compared in alkali at different potentials by cyclic voltammetry and chronoamperometry. The sensors characterized by fixed potential chronoamperometry are found to be sufficiently sensitive to glucose at different negative potentials like −0.65 V, −0.40 V, −0.10 V with respect to Hg/HgO electrode (E0≈0.1 V), where the reactions of glucose oxidation are different. The sensor constructed with Pd94Cu6 nanocatalyst shows an outstanding sensitivity of 10.1 mA cm−2 mM−1 which is considerably higher than that constructed with similarly synthesized Pd nanoparticles at any potential and that found in the literature of Pd based glucose sensors. The lower detection limit and response time obtained with Pd94Cu6 nanoparticles are 10 μM and 3 s respectively. These sensors also exhibit high specificity to glucose and significant anti‐interference property against some common species like ascorbic acid (AA), uric acid (UA) and some monosaccharides whose interfering effects are found to decrease with decrease of potential of glucose oxidation. The electrocatalytic ability of the synthesized Pd and Pd94Cu6 nanoparticles toward glucose oxidation has also found promising in blood sample at different potentials.
