摘要

摘要: 利用水合肼还原法制备的TiO₂/Cu₂O复合光催化剂对活性炭纤维(ACF)进行改性,利用SEM、XPS、BET以及XRD对其进行表征,研究改性后ACF的性质及其脱硫脱硝效果。研究表明,TiO₂/Cu₂O同时改性后的ACF表面孔径减小,但表面石墨碳和羰基(C=O)官能团增加,增强了ACF对NO和SO₂的吸附能力,从而提高了脱硫脱硝的效率,该催化剂在40℃、可见光的催化下脱硫效率达90%,脱硝效率达60%。

Abstract: TiO₂/Cu₂O composite photocatalysts were prepared by hydration hydrazine reduction method and loaded on activated carbon fiber (ACF). The SEM, XPS, BET and XRD were used to analyze the property changes and reaction behaviors of catalysts. The NO and SO₂ removal efficiencies of the catalysts were also investigated. The results show that the pore size of ACF is decreased after modified by TiO₂/Cu₂O. The surface functional groups including graphite carbon and carbonyl group are increased, which enhance the NO and SO₂ adsorption capacity of ACF. The highest desulfurization and denitrification efficiency are 90% and 60% at 40℃ under visible-light.
