报告简介：
Many attempts have paid to the development of low powers consumption and highly sensitive gas micro-nano sensors towards different applications including of air pollution monitoring, and breath analysis. Advanced nanomaterials of 1D and 2D materials have been widely applied in gas sensors, but the limitation of low sensitivity, and low selectivity as well as high power consumption limits their potential applications. In this talk, I will introduce our cutting-edge research on the
controlled synthesis of advanced nanomaterials for gas sensors;
new designed sensor structure with novel working principle for low power consumption,
functionalization to enhance the sensitivity.
Our study targets to the controlled synthesis and doping of one-dimensional (1D) metal oxides, and two-dimensional (2D) transition metal dichalcogenides (TMDs) to explain the role of doping elements to the fundamental properties of the host materials. We pointed out that the new phenomena of undoped and doped materials enable the fabrication of high-performance gas nanosensors with small size, low power consumption, low gas detection limit, high sensitivity, and high selectivity based on novel design of 1D and 2D materials will be achieved to open a new strategic application in environmental monitoring and exhaled breath analysis. We also combined the artificial intelligence to classify the mixed gases for actual application in portable devices.
