Au-on-Pd bimetallic nanoparticles applied to the voltammetric determination and monitoring of 4-nitroaniline in environmental samples

Studies on the Catalytic Properties of Palladium–Niobium Electrocatalysts Supported on Carbon Nano-onions toward Isopropanol and Ethanol Electro-oxidation in an Alkaline Medium

“…The existence of Nb promoted the removal of poisonous intermediates on the Pd surface. This resulted in a low poisoning rate due to fewer blockages on the Pd active sites by the poisonous intermediates …”

A novel double‐sampled square‐wave voltammetric technique combined with quadruple‐disk metallic‐glassy carbon electronic tongue for isotonic beverages profiling

“…The response of these electrodes is influenced by the difference in the electronic properties between the two metals, which can result in enhanced response parameters. Examples of such electrodes can be: bimetallic Au-on-Pd nanoparticles applied with a modified GCE used in determination and monitoring of 4-nitroaniline in environmental samples [27], immobilized polypyrrole conducting with bimetallic PtÀ Pd nanoparticles applied for oxidation of 4-(hydroxymethyl) pyridine [28], glassy carbon electrode modified with nanocomposite prepared from Co-Nd bimetallic nanoparticles, alumina nanoparticles and functionalized multiwalled carbon nanotubes, made through simple mechanical mixing applied in determination of epinephrine [29], CuÀ Pt bimetallic nanocatalysts deposited on borondoped diamond electrodes for the simple and rapid detection of methanol [30] or bimetallic AuÀ Pd on multiwalled carbon nanotubes for detection of dopamine [31].…”

Selective identification of p-nitroaniline by bromine-mediated polarization of carbon dots

“…Although a variety of methods have been established to detect PNA, such as surface enhanced Raman spectroscopy, 6 high performance liquid chromatography, 7 gas chromatography–mass spectrometry, 8 electrochemical methods, 9–11 ion migration spectrometry, 12 etc ., their application is limited due to their high cost, complex operation, long test time and weak anti-interference ability. Recently, fluorescent sensors have been widely used for the detection of anions, cations and some small organic molecules because of their advantages of simple operation, fast reaction speed and high sensitivity.…”
