Electrosynthesis and characterization of copper dicyanamide materials

X-ray diffraction and infrared reflection spectroscopy data have confirmed the electrosynthesis of copper dicyanamide films by cyclic voltammetry potentiostatic electrolysis. An insoluble Cu(I)dca film can be synthesized on a gold or electrode reduction Cu(II) oxidation Cu(0) in aqueous methanolic solutions containing ions. By resorting to use ruthenium hexaammine redox probe was shown electronically conductive although deposition rate decreases when formation proceeds. Depending applied potential, not only but also Cu(II)dca formed presence ions dissolved methanol. The powder obtained electrolysis at 1 V vs Hg/Hg2SO4 made essentially presents specific surface area (183 ± 59) m2/g. This material adsorb preferentially methyl orange Congo red dyes compared methylene blue whereas no marked difference is between CO CO2 adsorption.
