The excessive indoor poisonous gases (such as formaldehyde, toluene, acetone, CO, NH3, and so on) have already been becoming the serious harms to human health. In order to reduce and control pollutions, and create a fresh and comfortable indoor air environment, one of the hot and interesting research areas of new sensitive materials and devices is the design and synthesis of the high-performance gas sensitive materials for detection of the indoor poisonous gases, the interaction mechanism between the gas sensitive materials and the indoor poisonous gases, and the development of the series high-performance sensors for indoor poisonous gases..Using the advantages of nanoporous tin-oxide-based composite materials synthesized and assembled by self-assembly technology, this project will mainly carry out the following researches: (1) study on the self-assembly synthesis and the sensitive performances of the nanoporous tin-oxide-based composite materials with high surface area and thermal stability to the indoor poisonous gases; (2) study on the synthesis mechanism of the nanoporous tin-oxide-based composite materials and their gas sensitive mechanism for indoor poisonous gases; (3) to obtain the series of high-performance sensitive materials with good sensitivity properties and application prospects for the indoor poisonous gases. The results of the research project will have the important scientific and practical significance for the detection, monitoring and control of the indoor poisonous gases.
