今天給大家分享的是2014年6月份 《ACS Appl. Mater. Interfaces》上發(fā)表的一篇名為：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
