Abstract

The volatile organic compound (VOC) sensing properties of TiO2 nanotube / copper octakisalkylthiophthalocyanine {((C6S)8PcCu} hybrid structure were investigated at room temperature. Ti thin films were anodized in aqueous HF (0.5 wt %) electrolytes by applying 10 V at room temperature to form TiO2 nanotube arrays. Then (C6S)8PcCu were coated on to TiO2 nanotubes with two gold electrodes, using jet - spray technique in an inert ambient from a solution of (C6S)8PcCu in chloroform. The hybrid sensor was tested for concentration range of 500 to 5000 ppm VOC at room temperature. It is found that the sensor response of the hybrid sensor is higher than (C6S)8PcCu thin film sensor. The highest sensor response of the hybrid sensor is observed for isopropyl alcohol.
