摘要: Nickel oxide has number of applications in fields like electronic, magnetic and in industries the requirement of nickel oxide (NiO) is in large quantity and in high purity state. The present rapid green process invented for the preparation of nickel oxide (NiO) from analytical reagent grade solid nickel chloride (NiCl2.6H2O) and specifically opaque latex of Jatropha curcas plant as a green solvent. This process results in covering the green chemistry principles like waste prevention, all atoms converted to oxide, less hazards, non-toxic material generation, due to short time requirement for the real time analysis pollution prevention occurred, energy required for this process was minimized. Material was analysed by using XRD, EDAX and SEM characterization methods. This results in perfectly matches to (JCPDF: 00-432-0490) card number for NiO.

摘要: A method for preparing a transition-metal adamantane carboxylate salt is presented. The method includes mixing a transition-metal hydroxide and a diamondoid compound having at least one carboxylic acid moiety to form a reactant mixture, where M is a transition metal. Further, the method includes hydrothermally treating the reactant mixture at a reaction temperature for a reaction time to form the transition-metal adamantane carboxylate salt.
