A simple method for the synthesis of Nano-rod like copper oxide nanostructure has been reported using sodium hydroxide (NaOH) and ultrapure deionized (DI) water and ethanol as precursor. Efforts were made to see effort of sodium hydroxide amount of different properties of the materials thus three sample were synthesized with different amount of sodium hydroxide precursors. The as-prepared sample was characterized by X-Ray diffraction (XRD), field emission scanning electron spectroscope study. Also the samples were characterized further with the help of Fourier-Transformed infrared (FTIR) spectroscopic study as well as Raman Spectroscopic study taken in reflection mode. XRD conforms the proper Phase formation of the sample whereas the microscopic analysis has given an idea about the morphological as well as dimensional information. FTIR study gives the information regarding the different bonding present in sample. Reflection study shows that, due to the change in the precursor amount, there is a marked difference in the reflection spectra as well as optical gap of the sample.

“…On the other hand, nanostructured copper oxide has captured the attention of researchers due to low-cost elaboration, as well as potential applications in various areas, such as catalysts, capacitors, other electrochemical, photovoltaic cells, nano-field emission devices and gas sensors. Indeed, particles, plates, thin films and CuO nanowires were manufactured for the detection of CO, NO 2 , H 2 and H 2 S [8][9][10][11][12][13]. Depending on the gas detection mechanism, the adsorption/desorption process occurs on the surface, leading to the increase or reduction of electronal (type n) or vacancies (type p), which leads to increased performance of nanostructured sensors [16].…”

Nanostructured transition metal oxides obtained by SPVD

The interest in the unique properties associated with materials having structures on a nanometer scale has been increasing at an exponential rate in last decade. Transition metal oxides are preferred materials for catalytic applications due to their half-filled d orbitals that make them exist in different oxidation states. Transition metal oxides show a broad structural variety due to their ability to form phases of varying metal to oxygen ratios reflecting multiple stable oxidation states of the metal ions. The Solar Physical Vapor Deposition (SPVD) presented in the paper as elaboration method is an original process to prepare nanopowders working under concentrated sunlight in 2 kW solar furnaces. The influence of the synthesis parameters on the chemical and microstructural characteristics of zinc and manganese oxides synthesized nanophases has been systematically studied using XRD, SEM and EDX.

CuBO 2 is a novel material in the research field of transparent conducting oxide. In this study, CuBO 2 nanostructures have been synthesized via sol-gel method. The phase formation is confirmed using an X-ray diffractometer. Detailed morphological analysis is performed by field emission scanning electron microscopy and transmission electron microscopy. A novel uniform nanonetwork-like structure is obtained and its band gap is found to be 4.24 eV. In ultraviolet light irradiation, this as-synthesized sample shows efficient photocatalytic activity for degradation of organic dye Rhodamine B. The degradation efficiency and the rate constant were calculated as ∼70% and 1.32 × 10 −3 min −1 , respectively. This nanonetwork-like structure can be a potential candidate as the base material to attach various metals and metal oxide nanostructures to get highly efficient future photocatalysts. As a result, this study opens up a new gateway to fabricate novel environment-friendly nanocatalysts with high performance.
