Abstract
TiO2/rGO nanocomposite is synthesized by using pulsed laser ablation in liquid method, the UV–VIS absorption spectra and Scanning electron microscopy (SEM) TiO2/rGO) nanocomposites reveal absorption spectra in ultraviolet region and that the particles were in an aggregated state shrubbery, showed AFM image the size of each image showed that the membrane materials and through the two-dimensional and three-dimensional examines are homogeneous, noting that there are no spaces in the surface. Electrical properties of the nanocomposite improved markedly with bare TiO2NPs, without significantly changing the morphology of the TiO2NPs. Ammonia-sensing acts for (TiO2/rGO) layered film tackled. Sensing behavior of the (TiO2rGO) nanocomposites examined under the 100 ppm of NH3 environment. The (TiO2/rGO-1) nanocomposite clarified a high reaction to NH3 gas (48 %) in room temperature.
