Amorphous titanium dioxide (TiO2) and gold (Au) dopedTiO2-based surface acoustic wave (SAW) sensors have been investigated as hydrogen gas detectors. The nanocrystal-dopedTiO2films were synthesized through a sol-gel route, mixing a Ti-butoxide-based solution with diluted colloidal gold nanoparticles. The films were deposited via spin coating onto64∘YXLiNbO3SAW transducers in a helium atmosphere. The SAW gas sensors were operated at various temperatures between 150 and310∘C. It was found that gold doping onTiO2increased the device sensitivity and reduced the optimum operating temperature.

Synthesis of titanium dioxide sol was prepared by sol-gel method, using tetrabutyl titanate as source, ethanol as solvent, acetic acid as complexing agent. A transparent sol aging in air 30min, titanium dioxide films were prepared by using spin coating method. Congo red degradation was investigated by TiO2photocatalysis. Study the efficiency of decolorization was influenced by the coating times, heat-treated time, the initial concentration of congo red and solution pH.
