Anatase TiO2 on graphene-coated cotton flexible sensor at room temperature.

Carbon Monoxide (CO) is one of the pollutant gases produced widely in modern industry. Therefore, it should be detected easily and with the simplest method available. TiO₂ as a Metal-Oxide Semiconductor has been used as CO sensor material, but most TiO₂-based sensors work in high temperatures. TiO₂ synthesized by solvothermal is deposited using Chemical Bath Deposition (CBD) on Graphene-layered fabric cotton. It can show conductance changes in the presence of CO but tiny differences between the concentrations. [ABSTRACT FROM AUTHOR]
