“…Some other deposits, such as semiconductor silicon [25,26], transition metals of tantalum and copper, selenium and indium [27][28][29] were obtained from this kind of ionic liquid. The electrodeposit of amorphous manganese on tungsten, nickel, or copper foils was identified by the energy-dispersive spectrometer [30,31]. The current efficiency was higher than 97% regardless of the applied potential.…”

“…To reduce the cost of RuO 2 some low cost metal oxides such as NiO, CoOx and MnO x etc. have been investigated as electrode materials for electrochemical capacitors [26,27]. Nano-composites of these metal oxides with high surface area carbon materials have been shown to enhance the capacitance as reported by Zheng et al [28].…”

Polyanine and its nanocomposite WO 3 /PANI films were deposited on Fluorine doped tin oxide (FTO) glass slides by simple Chemical Bath Deposition Method. The morphology and crystalline structure of the composite film was studied using Atomic force (AFM) and Scanning Electron Microscopy, while the electrochemical capacitive properties were determined using Cyclic Voltammetry (CV), chronopotentiometry (CP) and electrochemical impedance spectroscopy (EIS). The WO 3 / PANI nano-composite exhibited multiple colors (electrochromism) during the CV scans, from brownish green to transparent to light green then back to brownish green. Surprisingly, the integration of the PANI with the WO 3 led to synergistic performance of nanohybrid wherein a true electrochemical double layer capacitor was obtained. Also, interestingly and unlike literature reports, the CBD method led to excellent capacitance retention (> 98%) of the PANI even at 1000 continuous cycles. This work demonstrates that simple CBD can be used to get WO 3 / PANI films that give good electrochromism and pseudocapacitance comparable to the ones obtained by other methods. Hence the obtained nanocomposite film of WO 3 / PANI can be a promising material for electrochromic and energy storage applications.

“…38 Surface coverage is insufficient at −0.8 V and −0.9 V while at −1.1 V non uniform deposit with large lumps of Pd is observed. At −1.0 V uniform Pd deposit with good surface coverage is obtained which gives better electro catalytic The results obtained on morphology using FESEM are further substantiated by TEM images as shown in Fig.…”

A fuel cell based amperometric room temperature hydrogen sensor with Nafion as proton conducting electrolyte, Pd as sensing electrode, Pt as both counter and reference electrodes has been developed. Sensing electrode was prepared by electrodeposition of Pd on carbon gas diffusion electrode using room temperature ionic liquid electrolyte. Pt spray coated on gas diffusion electrode forms the counter electrode in the sensor. Pd electrodeposition was carried out at an applied potential of −1.0 V vs Pd wire and resulted in the formation of Pd clusters. The microstructure of electrodeposited Pd was investigated using field emission scanning electron microscope (FESEM) and transmission electron microscope (TEM). The crystal structure of the Pd nanoparticles was indexed to face centered cubic by X-ray diffraction (XRD) and selected area electron diffraction (SAED). X-ray photoelectron spectroscopy (XPS) confirmed metallic form of the deposited Pd nanoparticles. The scratch test endorsed the fact that Pd nanoparticles adhered firmly to the surface of the gas diffusion electrode and it is found to be stable up to the load of 2 N. Range of response of the sensor to H 2 was in the concentration range 1% to 5% and found to be linear.
