Controllable synthesis of submicrometer-sized copper crystallites with different morphologies

Template‐Free Synthesis of Magnetic Chains Self‐Assembled from Urchin‐Like Hierarchical Ni Nanostructures

“…According to the Scherrer formula: [30] D = kλ/(βcosθ) (where D is the average dimension of particles, K is the Scherrer constant, and β is the FWHM of a reflection), the above-mentioned result indicates that the average grain diameter of the as-obtained particles increases gradually, which is consistent with the SEM results shown in Figure 4. Apart from the reaction time, EDA, which is an important ligand for metal ions and has been widely employed as a shape controller and stabilizer in the synthesis of Fe 3 O 4 hollow microspheres, [22] fine handkerchief-like Ni and NiCo nanoalloys, [23] ZnSe flower-like nanoarchitectures, [24] hollow CdS nanoboxes, [25] hexagonal, star-shaped and snowflake-shaped Cu structures, [26] dendrite-like SnS, [27] nanorods and flower-like ZnO structures, [28] and submicrometersized Cu and Ag crystallites, [29] has a significant effect on the formation, morphology, and structure of the as-obtained Ni products. We have systematically investigated the effect of different amounts of EDA in the range 0-8 mL.…”

Copper succinate nanoparticles synthesis by electrochemical method: Effect of pH on structural, thermal and textural properties

“…Peaks at 1398 cm À 1 , 1472 cm À 1 and 1561 cm À 1 indicate presence of metal carbonyl group in resultant nanoparticles [8]. Corresponding bonds represent the interaction between succinic acid and copper to form copper succinate [9]. Peak at 1200 cm À 1 indicates the presence of metal salt (Cu-O-C) group [8].…”

“…Peak at 1200 cm À 1 indicates the presence of metal salt (Cu-O-C) group [8]. Nanoparticles obtained at pH [8][9][10][11] show presence of similar functional groups as at pH 7. Some peaks originally present in succinic acid shift after coordinating with copper towards lower wave number.…”

“…Copper nanoparticles have several important applications like in water gas shift catalysts and gas detoxification catalysts [1,2], medicine and biology [3,4], inorganic biocide [5,6], ceramics, pigments and cosmetics, sensors, microelectronics, and many other areas of nanotechnology [7,8]. Moreover, copper nanoparticles are being used as an alternate for gold, silver and platinum nanoparticles in the field of thermal conducting materials and micro-electronics applications [9,10].…”

One-pot synthesis of size and shape controlled copper nanostructures in aqueous media and their application for fast catalytic degradation of organic dyes

“…The study of the synthesis and stabilisation of copper nanoparticles (CuNPs) is of great importance due to unique properties such as low cost, high electrical conductivity, and excellent processing properties 1 and their diverse applications in antimicrobial activity, 2 bio sensing, 3 lubrication, 4 optics, 5 and catalysis. 6 Recently, a few different types of synthetic methods such as hydrothermal, 7 solvothermal, 8 microemulsion, 9 metal salt reduction, 10 polyol process, 11 supercritical techniques, 12 sonochemical reduction, 13 microwave heating 14 and mechanochemical process 15 for making shaped copper nanoparticles including particles, rods or cubes have been reported. To minimise copper oxidation, previous syntheses have typically been performed in non-aqueous media, at lower precursor concentrations, and under the protection of an inert gas.…”
