Abstract
We have synthesized pure, mixed and multicomponent structures by coupling different cost-effective techniques. Prepared TiO2-based hierarchically assembled nanostructures have been thoroughly characterized by scanning electron microscope, X-ray diffraction, Raman spectroscopy and X-ray photoelectron spectroscopy. The sensing properties of materials have been studied towards explosive and toxic gaseous compounds. Investigations have shown the material crystalline structure, the variation of mixture concentration in the material and the modification of carbon-based layers have crucial effect on the response and the selectivity of materials. The obtained results demonstrate that the prepared multicomponent structures can be applied in the area of chemical sensors for the environmental monitoring and medical diagnoses.
