通过再沉淀法制备了富勒烯C60/酞菁的复合纳米微粒。这种复合纳米微粒由于C60分子和酞菁分子间的π-π相互作用而具有电子给体-受体(donor-acceptor)结构,而且这种微粒的尺寸可通过选择再沉淀过程中使用的溶剂来进行控制。此外,这种微粒与Nafion结合后,表现出去除三甲胺的光催化性能,而且其光催化活性优于C60微粒/Nafion或酞菁微粒/Nafion复合物。该结果表明电子给体-受体结构可通过促进有机半导体的电荷分离来增强光催化的性能,从而揭示了一种新颖的基于电子给体-受体结构的有机光催化剂。
Fullerene C60 / phthalocyanine composite nanoparticles were prepared by reprecipitation method. This composite nanoparticle has an electron donor-acceptor structure due to the π-π interaction between the C60 molecule and the phthalocyanine molecule, and the size of such a microparticle can be determined by selecting the solvent used in the reprecipitation process To control. In addition, the combination of Nafion with this microparticle showed the photocatalytic activity of removing trimethylamine and its photocatalytic activity was superior to that of C60 microparticles / Nafion or phthalocyanine microparticles / Nafion composite. The results indicate that the electron donor-acceptor structure can enhance photocatalytic performance by promoting the charge separation of organic semiconductors, thus revealing a novel organic photocatalyst based on the electron donor-acceptor structure.
