Growth of novel nanostructured copper oxide (CuO) films on copper foil

Cupric oxide nanoflowers synthesized with a simple solution route and their field emission

“…Especially, some CuO nanostructures have received considerable attention due to their novel physical and chemical properties that are not available from bulk CuO [8][9][10][11][12][13]. So far, a variety of approaches to fabricating CuO nanostructures have been developed, including thermal oxidation of Cu substrates in air within the temperature range from 400 to 700 1C [9], wet chemical method involving Cu(NO 3 ) 2 Á 3H 2 O and NaOH [11], reaction between thermally evaporated Cu and O 2 plasma [14], and heat treatment of Cu(OH) 2 fabricated by a coordination self-assembly method in a dilute ammonia solution [15].…”

Electric Field Enhanced Synthesis of Copper Hydroxide Nanostructures for Supercapacitor Application

“…20 Orthorhombic copper hydroxide (Cu(OH) 2 ) nanostructures are copper-based materials with remarkable sensitivity to the intercalation of molecular anions, making these materials good candidates in sensor applications. 21 Furthermore, these nanostructures can be easily converted to CuO 20,22,23 which is known as a p-type semiconductor with a narrow indirect bandgap of 1.2-1.5 eV at room temperature (RT), 24,25 with variety of applications in sensors, solar cells, Li-ion battery electrodes 26,27 and supercapacitors. [28][29][30][31][32] CuO as a supercapacitor electrode has speci¯c capacitance in the range of 100-620 F/g.…”

A novel chemical preparation of Ni(OH)2/CuO nanocomposite thin films for supercapacitive applications

“…The unique characteristics of CuO such as high thermal and electrical conductivities, high mechanical strength and high-temperature durability [23] had given a wide utility preparation of organicinorganic nanostructured composites. Recent studies, opened up applications of the transition cupric oxide as gas sensors [27,28], optical switch [29], magnetic storage media [30], lithium batteries [31], and solar cells [32,33] owing to its photoconductive and photochemical properties. Several techniques employed in the deposition of both Ni oxide and cupric oxide are not limited to hydrothermal decomposition [34], self catalytic growth [35], solvo-thermal routes [36], electrochemical method [37], electron beam evaporation [38], dc magnetron sputtering [39], chemical vapor deposition (CVD) [40], chemical bath deposition (CBD) [41,42], sol-gel technology [43], etc.…”
