• response to NO2 and acetone vapor. In contrast to sensors in which the sensing element consists only of rGO, sensors based on semiconductor oxide compositions, for example, WO3 with rGO, have a higher response. In the case of pure rGO, the restoration of the original parameters of the sensors may not be

• gas sensitivity of semiconductor oxide compositions with graphene. The reasons for the increase in the response and decrease in the operating temperature of metal oxides combined with non-oxidized graphene are synergetic effects between graphene and metal oxides as a result of chemical bonds between

• increases the number of catalytically active sites [15]. In a word, improved crystallinity and small grain size of oxides, together with well-ordered mesopores contribute to the photocatalytic activity of semiconductor oxide films with ordered mesoporous structures.
