【摘要】 利用傅里叶变换显微红外光谱仪（micro-FTIR）研究异戊二烯在α-Al₂O₃表面的氧化反应。结果表明异戊二烯、臭氧和二氧化硫可以在α-Al₂O₃表面反应生成羰基化合物和硫酸盐,并且水的存在对硫酸盐的生成有抑制作用。更多还原

【Abstract】 This study focus on the oxidation reaction of isoprene on α-Alumina by using a gas-flow system combined with microscopie Fourier transform infrared(micro-FTIR) spectrometer.The results show that isoprene,ozone and sulfur dioxide can react to produce carbonyl compound and sulfate on the surface of α-Alumina particles.The reaction is sensitive to water and surrounding water significantly suppresses the formation of the sulfate.Moreover,the formation rate of sulfate at dry condition is faster than that of reaction at 60% RH by the sulfate peak area along with the reaction time.更多还原
