A hybrid material consisting of bulk-reduced TiO2, graphene oxide and polyaniline for resistance based sensing of gaseous ammonia at room temperature

A hybrid material consisting of bulk-reduced TiO2, graphene oxide (GO) and polyaniline (PANI) was fabricated by decorating TiO2 with GO, followed by in-situ oxidative chemical polymerization of aniline. The TiO2 nanoparticles (NPs) with thermally stable bulk reduction states were initially prepared from porous amorphous titanium as the precursor. The TiO2 NPs and GO were chemically conjugated to each other via amide bonds to improve the...
