今天给大家分享的是2014年6月份 《acs appl. mater. interfaces》上发表的一篇名为：role of polyaniline on the photocatalytic degradation and stability performance of the polyaniline/silver/silver phosphate composite under visible light

文章摘要如下：

polyaniline/silver/silver phosphate (pani/ag/ag₃po₄) composite was prepared by in situ depositing silver phosphate (ag₃po₄) nanoparticles on the surface of polyaniline (pani). the best photocatalytic rhodamine b degradation performance is obtained by the 20 wt % pani/ag/ag₃po₄ composite, which is approximately 4 times higher than that of pure ag₃po₄. meanwhile, the photocatalytic stability of ag₃po₄ is significantly improved by introducing pani into the pani/ag/ag₃po₄ composite. the dramatic promotion of the photocatalytic degradation performance and the photocatalytic stability can be attributed to the formation of a heterojunction electric field between pani and ag₃po₄, which is approximately 90 mv and points from ag₃po₄ to pani. the existence of this electric field can dramatically enhance the separation efficiency of the photogenerated electron–hole pairs, accelerate the transfer of photogenerated holes from ag₃po₄ to pani and therefore inhibit the self-oxidation of ag₃po₄
