摘要
近年来,酸雨、温室效应、臭氧层破坏、生产和生活中排放的大量有毒有害物质,都对地球环境造成了严重的破坏。环境问题已成为制约社会发展的瓶颈,也妨碍整个社会的可持续发展,同时也是社会对于化学工作者提出的一个新课题。经研究发现 CNTs 具有多孔的石墨结构,经改性分离后对氮氧化物有快速、强烈的吸附,可作为一种潜在的高性能吸附剂。将 CNTs 制成薄膜型的电阻式气敏传感器,相信会有更广泛的应用前景。
In these years, acid Rain, greenhouse effect, ozone Depletion and a large amounts of toxic and harmful waste have brought serious damage to our motherland - earth. The problem of environment has been the bottleneck of the development of our enconomy, and at the same time,it hampers the sustainable development of the whole society, and also chemical workers and researchers should pay more attention to this new field. It is investigated that CNTs has porous graphite structure, and has rapid, strong adsorption of nitrogen oxides after being modified and separated, which can be adopted as a potential high - performance adsorbent. If we can make CNTs into thin - film resistor of gas sensor, it is believed to have a bright Application prospects.
