【摘要】 随着全世界工业和经济的发展,人们已经意识到温室气体的排放给世界环境带来了巨大的影响。节能减排越来越受到人们的关注。近年来,低碳技术逐渐被世界各国重视,在能源、交通、生物等经济发展的各个领域都得到了一定的应用。本研究着眼于低碳道路交通技术,主要针对纳米二氧化钛对于汽车尾气中的CO、HC以及CO₂这些含碳化合物的催化分解效果进行了研究。结果表明,纳米二氧化钛在光照条件下对尾气中的含碳化合物具有显著的分解效果,光照越强,分解效果越好。更多还原

【Abstract】 As the great development of industry and economy all over the world,people have realized that the emission of greenhouse gases have brought significant impact to the environment of the earth.In recent years,people in most countries put more and more emphasis on low-carbon technics,which could be widely used in many areas such as energy,transportation and biology.In this study,we focus on low-carbon technic in transportation,and we made a large number of experiments about the efficiency of decomposition of carbide gases such as carbon monoxide,hydrocarbon and carbon dioxide from vehicles by nanometer Titanium dioxid.The results showed that nanometer Titanium dioxide can significantly decompose carbide gases from vehicles,and intensity of the illumination radiation affect it obviously.更多还原
