Facile synthesis of MWCNTs/Ag3PO4: novel photocatalysts with enhanced photocatalytic activity under visible light

The present communication demonstrates a facile strategy toward rapid in situ synthesis of Ag3PO4 nanoparticles onto the surface of multi-walled carbon nanotubes (MWCNTs/Ag3PO4) by adding Na2HPO4 into the mixture of MWCNTs and AgNO3 ethylene glycol solution under stirring. We further demonstrate the use of such composites as novel photocatalysts toward photodecomposition of rhodamine B under visible light. It suggests that varied loading of MWCNTs in the composites has significant influence on the photocatalytic activity and the MWCNTs2.5 %/Ag3PO4 exhibits the highest photocatalytic performance.
