Some features of alcohols electrooxidation process on Pd, Rh and PdRh catalysts

A tandem of GC‐MS and electroanalysis for a rapid chemical profiling of bacterial extracellular matrix

“…Remarkably, the spiking of ECMs containing glycerol by additional amount of glycerol in the concentration level of 50-100 mM also led to the appearance of the novel low-potential anodic peak in CV plot at approx. ~0.1 V. This peak corresponds to glycerol electrooxidation at a low potential (Figure 9) was previously obtained in model solution (Figure 4) and corresponded to oxidation of alcohol on the reduced Pd surface [11,27]. In other words, glycerol oxidation at Pd-ink modified SPEs at pH 12 could be affected by the concentration of glycerol (i) and type of the used matrix/media (ii).…”

“…There are two anodic waves at −0.1 and 0.6 V corresponded to glycerol electrooxidation and the cathodic wave at −0.3 V with a compromise current between the cathodic reduction of Pd‐surface oxides formed during the anodic scan and anodic glycerol electrooxidation. The latter compromise current is typical for Pd electrodes operated in alcohol alkaline solutions [11, 14]. The second anodic peak at a higher potential corresponded to glycerol oxidation on the oxidized Pd surfaces.…”

“…provide a good basis for a rapid and simple samples profiling with a high sensitivity and resolution. Thus, electroanalysis of alcohols can be carried out during only several minutes at the surface of Pd, Rh or PdRh catalysts [11,12]. Selective and sensitive electrodetection of acetaldehyde and formaldehyde can be implemented in basic aqueous solutions by use of Ag and Pd nanoparticles-based electrocatalysts [13,14].…”

Investigation of the electrocatalytic reaction for the oxidation of alcohols through the formation of a metal organic framework (Mn-MIL-100)/polymer matrix on the surface of an Au electrode

“…11 Oxidation of alcohols, carbohydrates, or aldehyde derivatives can be performed with air in aqueous media, in the presence of palladium and platinum catalysts under optimal conditions, and with high efficiency (20-80 1C and atmospheric pressure). [12][13][14][15][16] These reactions are very important processes as they produce valuable products and are also more environmentally friendly due to the replacement of mineral heterogeneous catalysts with organic oxidizing compounds. [17][18][19][20][21][22][23] One of the main problems with using palladium-containing heterogeneous catalysts is that the catalysts become inactive or contaminated after chemical reactions.…”
