摘要

摘要: 为了进一步增强活性炭的吸附性能,通过在活性炭表面负载Pt纳米颗粒催化剂来提高活性炭的催化能力。采用扫描电镜、透射电镜、XRD对改性前后活性炭进行了表征,同时分别将未经过改性的活性炭(AC)和经过Pt纳米颗粒改性后的活性炭(PtNPs/AC)制备成过滤器,将过滤器安装于空气净化机内,置于30 m ³标准环境试验舱研究其在1 h测试周期内对二手烟中总挥发性有机物(TVOC)的吸附性能。结果表明,AC过滤器1 h对二手烟中TVOC的去除率为72.05%,PtNPs/AC过滤器的去除率为95.63%。由此可见,负载Pt催化剂大大提高了活性炭的吸附性能。

Abstract: To further enhance the adsorption properties of activated carbon (AC), platinum was planted on the surface of AC to enhance its catalytic properties. The obtained composite was characterized by scanning electron microscope (SEM), X-ray diffraction (XRD), transmission electron microscopy (TEM). After that, two filters were made respectively with unmodified AC and Pt nanoparticles modified AC (PtNPs/AC) as filtration layer, and planted in air purification machine. To further evaluate the adsorption properties of PtNPs/AC, the purification machine was placed in 30 m ³ standard environmental test chamber to study its adsorption ability to TVOC from secondhand smoke. The results showed that the removal efficiency of TVOC was 72.05% by using the filter with unmodified AC, while that of TVOC was 95.63% by using the filter with PtNPs/AC. It was thus indicated that the adsorption properties of AC can be remarkably increased by modification with Pt.
