The synthesis of various nanoscale materials, such as nanoparticles, nanowires of Au, Pt, Ni Co, Fe, Ag etc., by electrodeposition techniques have been demonstrated in this article. Both potentiostatic and galvanostatic methods were employed to carry out the electrodeposition process under different potential ranges, time durations, and current densities. The electrochemical behavior of the deposited nanoparticles on various substrates was investigated by cyclic voltammetric and chronoamperometric techniques. The synthesis of mono-dispersed gold (Au) nanoparticles on indium tin oxide (ITO) coated glass, preparation of Au nanorods on nanoporous anodic alumina oxide (AAO), formation of Au nanoclusters on polypyrrole-modified glassy carbon electrode and one-step electrodeposition of nickel nanoparticle chains embedded in TiO 2 etc. have been highlighted in this article. The potential applications of synthesized nanoparticles such as the role of maghemite (Fe 2 O 3 ) in arsenic remediation, higher electrocatalytic activity of Ag nanoclusters for the reduction of benzyl chloride, and the role of C 60 nanoparticle-doped carbon film in fabrication processes are also presented in this article.

“…Recently, many groups have contributed their efforts to figure out the optimum conditions for the electrochemical deposition of PtNPs onto the support material surface. [37][38][39][40][41][42][43][44][45][46]67,68 Porous Pt aggregates of different shape and surface morphology have been electrochemically deposited on carbon nanotube layer. 41 Basically, two different deposition techniques were applied namely, pulse electrodeposition in which the working electrode was kept switching between two constant potentials and CV at a constant scan rate.…”

Platinum nanoparticles supported on multiwalled carbon nanotubes (Pt/MWCNT) were prepared using controlled electrochemical deposition from Ar-saturated H 2 PtCl 6 solution. The electrodeposition parameters were varied to observe change in the surface morphology and electrocatalytic activity of the Pt/MWCNT catalysts for oxygen reduction reaction (ORR). Surface morphology of the prepared catalysts was studied by scanning electron microscope (SEM) and scanning transmission electron microscope (STEM). For electrochemical characterization of the Pt/MWCNT electrocatalysts, CO-stripping and cyclic voltammetry (CV) experiments were performed in 0.05 M H 2 SO 4 solution. The ORR was studied in acid medium using the rotating disk electrode (RDE) method. The results obtained were analyzed and compared to those of commercial Pt/C. The size, shape and distribution of Pt particles as well as the electrochemical behavior of Pt/MWCNT modified electrodes showed strong dependence on the deposition parameters. The catalyst materials prepared by electrochemical deposition showed higher specific activities than commercial Pt/C catalyst. The Pt/MWCNT cathode materials showed remarkable stability during repetitive potential cycling in 0. Proton exchange membrane fuel cell (PEMFC) is identified as one of the most promising environmentally friendly sustainable energy conversion devices that efficiently convert fuel energy into electricity through electrochemical processes. [1][2][3] In comparison to the conventional internal combustion engine, low-temperature fuel cells are preferred for energy conversion in vehicles because of its green operating system, high efficiency and renewable energy resources.4,5 One of the most critical challenges for commercializing fuel cells is the development of more efficient, highly active and durable electrocatalysts to improve the sluggish kinetics of the oxygen reduction reaction (ORR). To date, Pt-based cathode catalysts have shown significantly high electrocatalytic activity toward the ORR as compared to other metals, alloys, core-shell structures, mixed metal oxides and nonnoble metal catalysts.6-15 Considerable efforts have been dedicated to minimize the amount of Pt loading and improve its electrocatalytic activity and durability, mainly because of its scarcity and high cost.

“…Due to the low concentrations of Pt on the supports, the loading of Pt by weight difference, thermogravimetric analysis, inductively coupled plasma analysis after acid washing or measurement of the concentration decrease of Pt precursor in the electrolyte as done in other studies [13,17,18] could not be performed. Also, the penetration depth of EDS is in the order of microns, which means that when measuring composition of the catalyst layer, the signal from the CP adds up to the signal of carbon of CNNs.…”

“…In order to tackle this problem, the carbon support is often functionalized. During this functionalization, by chemical treatment [16][17][18] or by electrochemical potential cycling [19], defects and functional groups, such us carbonyl, carboxyl and hydroxyl [17], are introduced on the carbon substrate which act as anchoring points for the ED process. In general, although a large amount of work on ED of platinum on carbon supports has been reported, the preparation of a controllable, highly dispersed loading of platinum on a carbon support still poses a challenge to the scientific community.…”

“…These electrodes were either functionalized with Pt or noble metal NPs for fuel cell applications or as sensors [11,17,33,34]. It was anticipated that this new preparation technique would reduce the electrode fabrication steps, improve the through-plane electrical conductivity, support-diffusion layer and could avoid the decrease in active surface area as in conventional catalyst pasting process [11,17,[33][34][35]. Additionally, fuel cell electrodes based on multiwalled CNTs, which have similar properties to CNNs as we shall discuss later, show superior durability and catalyst utilization compared to conventional carbon black supports [36].…”
