A photoconductive device of phosphotungstic acid (denoted as PW12) and TiO2 composite was fabricated. Compared to pristine TiO2, the composite materials of PW12-TiO2 displayed a remarkable enhancement (ca. 2000-fold) in their photocurrent values. Furthermore, the composite materials also exhibited good gas sensing performance for acetone.
