PANI基介孔球壳Ag/AgI复合光催化结构的构建及协同机制研究
Study on Establishment and Mechanism of a Photocatalytic System Consisting of PANI Mesoporous Sphere Based Ag/AgI Composite
【摘要】 以磺化聚苯乙烯(SPS)微球为模板,在其表面生成球形介孔聚苯胺(M-PANI),再通过原位反应法制备多种比例的M-PANI@Ag/Ag I复合材料。在可见光下,测试了其对罗丹明B(Rh B)染料溶液的光催化性能。结果表明,M-PANI@Ag/Ag I复合材料的光催化性能明显高于纯材料M-PANI和Ag/Ag I。分析表明:复合材料提高了吸附量,而且Ag颗粒表面的等离子共振(SPR)效应,使得电子-空穴在Ag I和M-PANI之间的传递和分离效率得到提高。
【Abstract】 Mesoporous spherical polyaniline(M-PANI) was formed on the surface of sulfonated polystyrene(SPS)microspheres acting as a template, and different ratios of M-PANI@Ag/Ag I composites were synthesized through in situ reaction. The photocatalytic experimental results showed that M-PANI@Ag/Ag I hybrids exhibited a superior Rh B degradation efficiency than M-PANI and Ag/Ag I. The enhanced photocatalytic activity is mainly due to the large adsorption capacity, and the surface plasmonic resonance(SPR) of Ag particles which can promote more efficiently charge separation and transportation between Ag I and M-PANI.
