Source abstract
Abstract
In this paper, the ternary composite of flower-like SnO 2 nanorod aggregates modified with Co 3O 4 nanoparticles grown on rGO sheets were synthesized by a two-step process of water heating and water bath, and characterized by SEM, TEM, XRD, EDS, and XPS. The gas-sensitive performance test results revealed that the 15-rGO/SnO 2/Co 3O 4 sensor exhibited a higher response value (I 0/I a=24.46) to 100 ppm xylene at the optimal working temperature of 175℃. In addition, the sensor could detect 10 ppb xylene, with a low detection limit. The gas-sensitive properties of 15-rGO/SnO 2/Co 3O 4 were significantly improved due to the large specific surface area of rGO flakes and SnO 2 slender nanorods, the catalytic action of p-type semiconductor Co 3O 4 and the existence of p-n-p double heterojunction. Due to the special nanostructure and synergistic effect of SnO 2, rGO and Co 3O 4, the 15-rGO/SnO 2/Co 3O 4 sensor enabled the efficient and selective detection of xylene.
