Synthesis and chemoresistive sensitivity to hydrogen of nanostructured CuO films
نویسندگان
چکیده
Highly porous CuO films up to 1 μm thick consisting of vertically oriented nanowires ~ 50 nm in diameter were synthesized by copper evaporation a vacuum arc discharge an argon/oxygen atmosphere followed deposition on heated substrates. The phase composition and polycrystalline nature the confirmed X-ray diffraction. On example gaseous hydrogen H 2 at sensor operating temperature 300 o C, sensory characteristics studied. qualitative mechanism effect gas electrical nanostructured film is described. Keywords: oxide, arc, nanowires, sensor.

Improving Sensitivity of a Chemoresistive Hydrogen Sensor by Combining ZIF-8 and ZIF-67 Nanocrystals
In the present work, nanostructures of zeolitic imidazolate frameworks (ZIF-8 and ZIF-67) were combined to obtain a novel chemoresistive sensor, improving the sensitivity of ZIF-67 and facilitating measurement of ZIF-8 by decreasing the resistivity. The sensor detected concentrations as low as 10 ppm of hydrogen increasing its resistivity about 4.5 times. The response of the sensor was compared...
متن کاملSynthesis and characterization of nanostructured bismuth selenide thin films.
Nanostructured bismuth selenide thin films have been successfully fabricated on a silicon substrate at low temperature by rational design of the precursor solution. Bi(2)Se(3) thin films were constructed of coalesced lamella in the thickness of 50-80 nm. The nucleation and growth process of Bi(2)Se(3) thin films, as well as the influence of solution chemistry on the film structure were investig...
متن کاملSynthesis and Characterization of Electropolymerized Nanostructured Aminophenylporphyrin Films
Porphyrins substituted at meso positions with aminophenyl groups undergo oxidative electropolymerization in a process analogous to the formation of polyaniline. Porphyrins that successfully generate polymer films on the electrode include those tetrasubstituted with four p-aminophenyl groups, trisubstituted, or transdisubstituted, but not cis-disubstituted or monosubstituted. The polymerization ...

15 صفحه اولComparative Study of Nanostructured Zr-Fe2O3 and CNT Modified Zr-Fe2O3 Thin Films for Photo Electrochemical Generation of Hydrogen
Nanostructured hematite thin films are doped with zirconium successfully and also modified by introducing CNT using sol-gel method for their implementation as photo-electrode in photo-electrochemical (PEC) cell for hydrogen generation. XRD, UV-visible spectroscopy and PEC study techniques are used to characterize the thin films. The PEC responses of thin films are improved by introducing carbon...
