Characterization of TiO2 surface modified by Molybdenum Oxide by Screen Printing Technique

Abstract

This work outlines an experimental and theoretical investigation of the effect of molybdenum (Mo) doping into the TiO₂ lattice metal oxide. In view of this, Mo is doped into the TiO₂ lattice in order to  used for gas sensing application. The Mo and TiO₂ powders fired at 450 ⁰C have the rutile structure. These powders were used to produce thick-film sensors. Four series of thick-film samples were fabricated by screen-printing techniques fired for 5h at 650 ⁰C. Surface modified thick films were analyzed for structural, morphological and electrical properties by XRD, SEM with EDX.
