Electrochemical deposition of ZnO in a room temperature ionic liquid: 1-Butyl-1-methylpyrrolidinium bis(trifluoromethane sulfonyl)imide

Preparation of crystalline zinc oxide films by one-step electrodeposition in Reline

“…The DPV of Ar bubbled Reline indicates that the solvent does not exhibit significant current in the potential range of À 1.700 and 0.500 V. For the oxygen bubbled zinc solution, a reduction peak was observed at À 1.100 V. Similar to a previous study [16], this peak can be attributed to the reduction of dissolved oxygen to superoxide. When zinc cations are available to react with the generated superoxide ions, zinc oxide film can be formed through a peroxide route [16]. As the result, a transparent and uniform ZnO film was deposited cathodically on Mo at À 1.500 V.…”

“…Pradhan and Leung [12] reported their deposition of ZnO nanopheres with diameters in 20-200 nm. Azaceta et al [16] studied electrodeposition of ZnO in an ionic liquid, 1-butyl-1-methylpyrrolidium bis(trifluoromethane sulfony)imide.…”

Physico-chemical properties and phase behaviour of piperidinium-based ionic liquids

“…The pyrrolidinium-based ILs were used in biological synthesis as catalysts [2], in chemical capacitors [3] and in the preparation of a novel class of polymer electrolytes based on polymer-ionic liquid gels [4]. The electrochemical reduction of palladium halide complexes, of nanocrystalline ZnO films and of tantalum and polycrystalline gold substrates using 1-butyl-1-methylpyrrolidinium bis{(trifluoromethyl)sulfonyl}imide, [BMPYR][NTf 2 ] was presented as well [5]. The specific properties of piperidinium-based ILs as a broad temperature range of liquid phase, extremely low vapour pressure as for all ILs, structure similarity to pyrrolidinium-based ILs, high solubility in water, low toxicity, lower density than pyrrolidinium-based ILs and other properties make these ILs potentially useful in many technological processes.…”

“…Nowadays, the interest of new ionic liquids (ILs) as alternatives for conventional organic solvents is increasing to the pyrrolidinium-based ILs [1][2][3][4][5] and piperidinium-based ILs [6][7][8][9][10][11][12][13][14]. The pyrrolidinium-based ILs were used in biological synthesis as catalysts [2], in chemical capacitors [3] and in the preparation of a novel class of polymer electrolytes based on polymer-ionic liquid gels [4].…”

Electrodeposition of Semiconductors in Ionic Liquids

“…In recent years ZnO has attracted a great interest as promising material for several technological applications (e.g., solar cells, UV light-emitting diodes, catalysis, photocatalysis, field emission, piezoelectric, gas sensing, etc.). In 2009, Azaceta et al [26] [29]. The authors studied the influence of temperature, substrate, the nature of the ionic liquid, and electrochemical deposition conditions on the morphology and the crystal structure of electrochemically made ZnO film.…”
