dc.description.abstract | Ternary hybrid composites are less explored for gas sensing purposes due to their complexity of structures. However, their complexity brings about a greater potential for resistance changes. In this study, we have syn-thesized a new ternary hybrid composite composed of polyaniline (PANI)-loaded Co3O4-TiO2 composite nano -particles (NPs) for acetone sensing at 25 degrees C. For this purpose, PANI and Co3O4 were added into TiO2 NPs using sol-gel method. The gas sensing characteristics of PANI-TiO2, Co3O4-TiO2 composite NPs and PANI-loaded Co3O4-TiO2 composite NPs sensors were systematically investigated with and without UV illumination (at 25 degrees C). Based on the sensing results, the ternary 0.01 wt% PANI-loaded 0.85TiO2 -0.15 Co3O4 composite NPs revealed the highest response to acetone under UV illumination at 25 degrees C. The enhanced performance of opti-mized gas sensor was due to formation of p-n heterojunctions, promising effects of PANI, and UV light effect. The results obtained herein, highlighted the possibility of making a highly reliable acetone sensor working at 25 degrees C using this compounds or related compounds. | - |
