PdCu alloy nanoclusters: generation and activity tuning for electrocatalytic oxidation of nitrite

Construction of Au nanoparticles on choline chloride modified glassy carbon electrode for sensitive detection of nitrite

“…Among these methods, electrochemical techniques are proved to be powerful tools due to their advantages of simple, inexpensive and fast analysis in combination with high sensitivity and selectivity. Recently, different kinds of nitrite sensors have been fabricated based on the chemical modification of electrodes (Santos et al, 2006;Zhu et al, 2007;Chen et al, 2008;Sousa et al, 2008;Salimi et al, 2008), but there is still an expanding demand for the development of more reliable and efficient sensors for sensitive analysis of nitrite.…”

Optimum Copper-Palladium Catalyst from a Combinatorial Library for Sensitive Non-Enzymatic Glucose Sensors

“…Even the addition of a small amount of Pd (8.2 at.%) showed a high electrocatalytic effect towards glucose oxidation due to the surface adsorption modification. Furthermore, this good performance of the electrode material is due to the alloyed Cu, which is responsible for a lowering effect of the electronic binding energy of Pd [33]. The fabricated Cu-Pd non-enzymatic glucose sensor exhibits a good sensitivity, low detection limit, and a wide linear concentration range compared to previously investigated glucose electrode materials.…”

“…Figure 4(b) presents the result of the cyclic voltammetric measurements of pure Pd in the absence (dotted gray line) and presence (gray line) of 35 mM of glucose. From the measurements without the addition of glucose, a well-defined anodic peak was observed at a potential of − 0.40 V (SHE) due to the adsorption and absorption of hydrogen [32,33]. At higher potentials (> 0.4 V) in the anodic scan direction, PdO is formed [34].…”

Enhanced electrocatalytic effects of Pd particles immobilized on GC surface on the nitrite oxidation reactions

“…In order to electrode modification, various types of materials have been used including polymeric films and metal nanoparticles. Most of the time some metals and bimetallic nanoparticles exhibits the amazing catalytic behavior such as Au, Pt, Pd, Fe, Cu, Sn, Ag [22][23][24][25][26]. However, deposition of nanoparticle on pure solid electrode play a great role in case of electrochemical analysis (response, kinetics and mechanism) of nitrite oxidation reaction (NOR) [27][28][29].…”
