Abstract:
The electrocatalytic hydrogenation (ECH) of cyclohexanone into cyclohexanol has been studied in aqueous media with electrocatalysts on composites powders. These powders are formed of nanoaggregates of nickel obtained through a physical deposition under vacuum on particles of Al(OH)3, AlO(OH), and γ-Al2O3. The ECH reaction was done in a dynamic cell. Its yield is closely dependent on the nature of the non-metallic particles whose nature greatly influences the adsorption–desorption of the organic compounds involved in the reaction.Key words: electrocatalysis, aluminum oxide, aluminum hydroxide,

We exploit the high local pH at the negative electrodes during water-based EPD to form nanoparticles of nickel-cobalt hydroxides in situ on the CNT surface.

Each type of stacking fault produces a characteristic non-uniform broadening of peaks in the X-ray powder diffraction pattern of nickel hydroxide.

Abstract:
The synthesis of the copper-poor and aluminum-rich layered double hydroxides (LDHs) of the CuAl4 type was optimized in detail in this work, by applying an intense mechanochemical treatment to activate the gibbsite starting reagent. The phase-pure forms of these LDHs were prepared for the first time; using copper nitrate and perchlorate salts during the syntheses turned out to be the key to avoiding the formation of copper hydroxide sideproducts. Based on the use of the optimized syntheses parameters, the preparation of layered triple and multiple hydroxides was also attempted using Ni(II), Co(

Powder X-ray diffraction analyses of the layered compounds revealed lattice parameters of a0 = 3.07 Å and c0 = 30 Å ( Co - DBS ) and a0 = 3.09 Å and c0 = 30 Å ( Ni - DBS ) in the hexagonal system. Dispersions of Co - DBS and Ni - DBS in 1-butanol produced colloidal solutions of nanosheets, [ Co - DBS ] delam and [ Ni - DBS ] delam , respec

AbstractThis study explores the lab prepared nickel hydroxide catalyzed oxidative degradation of Methylene Blue (MB) in aqueous medium using batch reactor. Nickel hydroxide was prepared by reaction of sodium hypochlorite, sodium hydroxide and nickel sulphate hexahydrate in distilled water. The catalytic oxidative degradation of Methylene Blue was explored in terms of various parameters like effect of time, hydrogen peroxide, temperature, initial concentration of dye, catalyst dosage and effect of speed of agitation on degradation of Methylene Blue. Experimental data was subjected to kinetics a

A novel hydrothermal stripping technique synthesis route, in which the nickel-loaded organic phase of naphthenic acid was directly stripped by water at 140-240 °C for 2.0 h to recover nickel as hydroxide precipitates, has been firstly developed. The nickel hydroxide powders synthesized by this route was the spherical β-Ni(OH)2 and had a small particle size in the range of 20-100 nm shown by XRD and TEM test. The results of electrochemical performances show that the nanometer β-Ni(OH)2 cathode materials have much higher discharge specific capacity, excellent capacity retention and cycle perform

Abstract:
Nanometer α-nickel hydroxide codoped with Cu and Al has been synthesized by the ultrasonic-assisted precipitation method. The crystal structure and particle size were analyzed by X-ray diffraction (XRD) and particle size distribution (PSD). The electrochemical performance of the samples was characterized by the charge/discharge test and cyclic voltammetry. The results of electrochemical tests demonstrated that the specific discharge capacity of Cu/Al codoped α-nickel hydroxide (330 mAh/g) is much higher than that of pure spherical nickel (240 mAh/g), and it exhibits a relatively good electroche
