摘要：

In the present work, hydrogen (H-2) gas sensing characteristics of hybrid composites prepared by sputtering of platinum (Pt) metal on the synthesized composites of functionalized multiwalled carbon nanotubes (F-MWCNTs) with selective metal oxides (nickel oxide and cuprous oxide) have been investigated. Both of these sensors are found to have fast response, complete resistance recovery, and good baseline stability at room temperature (25A degrees C). These sensors stably and reversibly respond to 0.05% concentration of H-2 gas at 25A degrees C. This sensing material was characterized by x-ray diffraction, Raman spectroscopy ,and scanning electron microscopy. To the best of our knowledge, detection of such low concentration of H-2 gas is reported here for the first time using F-MWCNTs/NiO/Pt and F-MWCNTs/Cu2O/Pt hybrid nanostructures at 25A degrees C.
