Preparation and Characterization of CuO Nanocrystals

Nanostructured copper oxides and phosphates from a new solid-state route

“…The most widely-known examples are in solution [4] but some solidstate [5][6][7][8] approaches have also been reported. Indeed, solution methods offer many advantages over the solid-state method, such as convenient control of the size and morphology of the nanoparticles and the ability to monitor the growth mechanism by other techniques such as optical spectroscopy for example.…”

“…Specifically for copper oxides, solid-state preparation methods have been reported [6,7,[10][11][12][13][14][15][16]. Xu et al [7] prepared CuO nanocrystals by a one-step solid-state reaction of CuCl 2 ⋅2H 2 O and NaOH, while Kawahashi and Shiho [6] obtained hollow spheres by calcination of a polymer-coated Cu(NO 3 ) 2 salt. A different approach involves the oxidation of solid Cu under air at 400 °C to give CuO nanorods [10].…”

Punica granatum flower extract mediated synthesis of Copper oxide Nanoparticle and evolution of its antibacterial activity

“…The reported conventional synthesis of Copper oxide NPs like chemical route [10], hydrothermal method [11], solid-state reaction method [12], thermal decomposition ofprecursor [13],etc leaves some toxic chemicals absorbed at the surface, which can cause adverse outcomes in medical applications.A variety of plant extracts such as Aloe veraLeaf [14],Ixora Coccinea [15], Pomegranate peel [16], Magnolia kobus [17], Carica Papaya [18],Manihot esculenta [19],Tridax procumbens [20], Azadirachta indica [21], Saraca indica [22]have been utilized for the greener way production of CuO NPs.…”

Copper Oxide Nanostructures; Syntheses and Characterization

“…However, the reports on the preparation and characterization of nanocrystalline CuO are relatively few to some other transition metal oxides such as zinc oxide, titanium dioxide, tin dioxide and iron oxide. Some methods for the preparation of nanocrystalline CuO have been reported recently such as the sonochemical method [0], sol-gel technique [7], one-step solid state reaction method at room temperature [8], electrochemical method [9], thermal decomposition of precursors [46] and coimplantation of metal and oxygen ions [44] etc. Laser ablation in liquid media is a 'top down' approach for the synthesis of nanomaterials having desired shape, size and chemical composition and surfaces free from chemical contamination, which are essential for further functionalization of nanomaterials for biological and sensing applications.…”
