Copper (II) Oxide Nanowires for p-type Conductometric NH3 Sensing

Copper (II) oxide thin film for methanol and ethanol sensing

A nanostructured copper (II) oxide film deposited by reactive DC-magnetron sputtering technique, has been studied for static sensor response towards methanol and ethanol by operating temperature and analyte concentration modulations. The optimum operating temperature (Topt) for the sensing of methanol and ethanol is observed to be 350 ̊C and 400 ̊C, respectively. The maximum sensitivity observe...

Formation of hybrid structures: copper oxide nanocrystals templated on ultralong copper nanowires for open network sensing at room temperature.

A facile large-scale synthesis approach for producing intrinsically p-type nanowires with uniform coverage of nanocrystals to form a highly interconnected porous nanowire network is of great demand for p-type sensing. Here, we have demonstrated synthesis of a very high aspect ratio (10(2)-10(5)) open network of interconnected hybrid nanocrystals-nanowire copper and copper oxide nanomaterials. T...

Electrochemical deposition of copper oxide nanowires for photoelectrochemical applications

We report a two-step electrochemical process to grow copper oxide nanowires without the use of templates and surfactants. The first step is to electrochemically corrode amorphous Cu–W oxides presputtered on fluorine-doped tin oxide (FTO) coated glass substrates under positive potentials. The second step is to use the corroded samples to grow copper oxide nanowires electrochemically under negati...

Improving Gas Sensing Properties of Tin Oxide Nanowires Palladium-Coated Using a Low Cost Technique

Thin films of SnO2 nanowires were successfully prepared by using chemical vapor deposition (CVD) process on quartz substrates. Afterwards, a thin  layer of palladium (Pd) as a catalyst was coated on top of nanowires. For the deposition of Pd, a simple and low cost technique of spray pyrolysis was employed, which caused an intensive enhancement on the sensing response of fabricated sensors...
