Titania/MWCNTS nanocomposites for low temperature hydrogen sensing

Metal oxide/carbon nanotubes hybrids composites are most promising for gas sensing, exhibiting synergic effects between the metal oxides and carbon phase. Actually, we are carrying out researches in this fi eld for developing new hybrids composites to be applied as sensing layers in resistive-type sensors. In the present work, we report efforts made in developing Pt-doped MWCNTs/TiO 2 composites for hydrogen sensing in air.
