【期刊论文】Low temperature synthesis of nanocrystalline Mn O by a 3 4 solvothermal method

Nanocrystalline trimanganese tetroxide (Mn O ) has been successfully synthesized by a solvothermal reaction in which 3 4 KMnO is reduced by CH OH or CH CH OH under pressure. Alcohol also served as the solvent in the method. The 4 3 32 reaction temperature can be as low as 80-1008C. Transmission electron micrographs and X-ray powder diffraction patterns show that the average particle sizes are 9-15 nm. From the electron spin resonance (ESR) pattern, hyperfine structure (six 21 31 absorption peaks of ESR) of Mn ion is observed on the main line of Mn. The mechanism for the formation of crystalline Mn O is proposed.

Li2MnO3 with different nanostructures was synthesized through a solid-state reaction. MnOOH nanorods and nanowires prepared via the hydrothermal method were used as precursors, respectively, to react with Li (OH). H2O to prepare nanostructured Li2MnO3 in the temperature range from 500 to 800 8C. The samples were characterized by XRD, TEM, ESR and FTIR results. Based on the experimental results, the dehydration-oxidation-combination (DOC) formation mechanism of Li2MnO3 was proposed.

【期刊论文】A hydrothermal synthesis of orthorhombic nanocrystalline cobalt diselenide CoSe2 Abstract

Nanocrystalline CoSe2 was successfully synthesized in the temperature range 90-170à℃ through a hydrothermal method. All the reflections in the XRD pattern of CoSe2 could be indexed as an orthorhombic system with cell parameters a 5 3.589, b 5 4.838, and c 5 5.713 Å. TEM images of the products showed a rod-like morphology. Disproportionation products of selenium in alkaline aqueous solution provide a convenient chalcogen source and make possible the synthesis of ransitionmetal selenides under hydrothermal conditions. The mechanism of the formation of CoSe2 is proposed.

【期刊论文】Controlled synthesis of Mn3O4 nanocrystallites and MnOOH nanorods by a solvothermal method
张卫新, Weixin Zhang a, a, Zeheng Yang a, b, Yi Liu a, Shupei Tang a, Xiaozhao Han a, Min Chen a

Mn3O4 nanoparticles and MnOOH nanorods were prepared, respectively, through successfully controlling a solvothermal reaction. An aqueous ethanol solution is used as the solvent. The ethanol volume percent in the solvent and reaction temperature have important effects on the composition of the final products. Experiments show that single phase of Mn3O4 nanoparticles can be prepared at higher reaction temperature and higher volume percent of ethanol (>50%), while single phase of MnOOH nanorods as single crystallites can be obtained at lower reaction temperature and lower volume percent of ethanol (2-10%). The controlled reactions allow the large-scale and cost-effective synthesis of Mn3O4 and MnOOH with different morphologies, which are expected to show unusual properties and potential applications in catalysis, electrochromic and magnetic materials as well as to afford good precursors for further synthesis and investigation of other manganese oxides.

We report the synthesis of nanostructured copper compound films on a copper surface under mild conditions. A series of low-dimensional structures including Cu(OH)2 fibers and scrolls, CuO sheets and whiskers, and Cu2(OH)2- CO3 rods have been successfully grown on the copper surfaces at ambient temperature and pressure. Most of the structures are phase-pure single crystallites. The films were formed by the direct oxidation of copper in aqueous solutions of NaOH with an oxidant (NH4)2S2O8. The evolution of the ultrafine structures as a function of the reaction conditions has been revealed, from fibers of Cu(OH)2 to scrolls of Cu(OH)2 to sheets or whiskers of CuO. By replacing NaOH with NaHCO3 in the synthesis, square/rectangular rod arrays of Cu2(OH)2CO3 were obtained. The controlled reactions allow the large-scale, template-free, cost-effective synthesis of copper compound films with ordered, uniform, stable, ultrafine structures.

【期刊论文】Room Temperature Synthesis of Cubic Nanocrystalline CdSe in Aqueous Solution

Reaction of an alkaline selenium solution with an aqueous solution of cadmium complex produces cubic nanocrystalline CdSe with an average particle size of 5 nm at room temperature under atmospheric pressure. The product was characterized through XRD, TEM, and XPS. The alkaline selenium solution makes CdSe crystallize well in aqueous solution. The use of cadmium complex instead of cadmium ion as a reagent can greatly reduce the byproduct. Furthermore the synthesis is performed conveniently and safely.
