Abstract
Chemical sensors based on metal oxides have been widely explored and used in the literature and have found different application fields as a function of their operating characteristics like selectivity, sensitivity, stability over time etc. Recently, some papers started to diffuse the idea that innovative chemical sensors could be obtained using two different metal oxides combined together providing enhanced sensing capabilities. In this paper the authors propose a new sensor based on perovskite support modified by a TiO2 based compound in order to test enhanced sensing performance. Moreover, the present work aims to show that nanocomposites obtained introducing in a matrix of a given metal oxide a second nano-structured metal oxide, which can act either as a catalyst or as a structure modifier, can provide improved sensitivity, selectivity and stability.
