“…Because the location of non-dimensional plots of experimental CAs are in the region of the 3D nucleation and growth, Scharifker -Mostany (SM) model can be used to represent processes occurring onto GCE surface during the Pd electrodeposition and provide several typical parameters. The form of SM model with the 3D nucleation and growth is given by [3,22]: (9) where  is the density of the Pd deposit and M is the atomic mass, No is the number density of active sites on the electrode surface, and A is the nucleation frequency per active site (s -1 ). zF is the molar charge transferred during the electrodeposition.…”

“…Palladium (Pd) is one of the most attractive metals because it has many excellent physical and chemical characteristics such as high catalytic activity, corrosion and wear resistance, thermal stability and biocompatibility properties [4,6,7]. Therefore, Pd and its compounds are used for many industrial applications, especially in catalytic and electrical devices such as hydrogenation catalysts [8], solar cell [9], oxidation of benzyl alcohol [10], ethanol oxidation [11], biosensors [12][13][14]. Pd has been electrodeposited on various electrodes containing polymer matrix, porous stainless steel electrode, copper and gold single crystal electrode, graphite substrate [15][16][17].…”

By using cyclic voltammetry (CV) and chronoamperometry (CA) techniques, the thermodynamics and kinetics of palladium electrodeposition on glassy carbon electrode (GCE) in deep eutectic solvent were studied. The Pd electrodeposition process via progressive 3D nucleation mechanism was controlled by the diffusion. Non-linear fitting methods were applied to obtain the kinetic parameters in the light of Harrison – Thirsk (H-T) and Scharifker – Hills (S-H) models for 3D nucleation and growth process. From that, the diffusion coefficient of Pd (II) in reline at ambient temperature was calculated by two different ways, and the obtained results showed that it is of cm2/s by using CV. Moreover, some important parameters such as the number density of active sites on the electrode surface (No) and the nucleation frequency per active site (A) were estimated by fitting experimental CAs data with Scharifker-Mostany model.

“…Another research team, A.F. Oliveira et al, carried out some interesting work on the synthesis of palladium-doped titanium dioxide nanoparticles and their characterization for solar cell applications [202]. The reverse micelle sol-gel method was employed for synthesis of TiO 2 and TiO 2 :Pd (i.e., doped with Pd), which yielded a satisfactory yield of between 80 and 90% for the synthesis of pure TiO 2 with various palladium dopings.…”

Palladium (Pd), a noble metal, has unique properties for C-C bond formation in reactions such as the Suzuki and Heck reactions. Besides Pd-based complexes, Pd NPs have also attracted significant attention for applications such as fuel cells, hydrogen storage, and sensors for gases such as H2 and non-enzymatic glucose, including catalysis. Additionally, Pd NPs are catalysts in environmental treatment to abstract organic and heavy-metal pollutants such as Cr (VI) by converting them to Cr(III). In terms of biological activity, Pd NPs were found to be active against Staphylococcus aureus and Escherichia coli, where 99.99% of bacteria were destroyed, while PVP-Pd NPs displayed anticancer activity against human breast cancer MCF7. Hence, in this review, we attempted to cover recent progress in the various applications of Pd NPs with emphasis on their application as sensors and catalysts for energy-related and other applications.
