A hybrid SnO2 modified multiwalled carbon nanotubes (MWCNTs) gas sensor is developed for the trace level (100 ppb) detection of NO2 at room temperature. simple method applied synthesis a sensor; SnO2-modified (MWCNTs), in which MWCNT bundles are uniformly coated situ with nanoparticles (∼4 nm). The concentration MWCNTs has been varied and MWCNT–SnO2 prepared using an optimum content (5 mg) found to exhibit enhanced sensing response characteristics (response = 5.5 × 103) towards 100 ppb low...
Round the globe, scientific communities have been searching for new materials “green” energy, producing efficiently both high power as well energy density.
Nitrogen-doped zinc oxide thin films (ZnO:N) have been realized as a potential matrix for the development of uric acid biosensor. The correlation between change in property ZnO film with N doping concentration and its biosensing response has studied. nitrogen dopant alters defects profile, thus improving charge transfer characteristics resulting an enhanced peak oxidation current cyclic voltammogram comparison to that pure film. studies reveal bio-electrode based on nitrogen-doped exhibits...
An efficient matrix comprising a hybrid nanocomposite of zinc oxide (ZnO) and multiwalled carbon nanotubes (MWCNTs) has been synthesised on indium tin coated glass slides (ITO/Glass) using chemical route deposition technique for the realization an urea biosensor. Urease (Urs) was used as specific enzyme detection physically immobilized over surface based (ZnO–MWCNT/ITO) electrode. The fabricated Urs/ZnO–MWCNT/ITO bioelectrode characterized electrochemical impedance spectroscopy (EIS) cyclic...
In the present work, comparative investigations on NO<sub>2</sub> gas sensing properties of hybrid nanocomposite thin films polyaniline (PANI), ZnO and PANI–ZnO towards at room temperature have been reported.
