Abstract

Silver nanoparticles (Ag NPs) may increase photocatalytic activity of widely used photocatalysts under visible light irradiation and decrease recombination probability of photogenerated electron and holes. In this paper, we studied three different preparation methods to obtain Ag/C3N4 nanocomposites. We used Ag nanoparticles a) synthesized by using sodium borohydride, b) synthesized by using UV 365 nm LED irradiation and c) already prepared and purchased from company Nano Iron. The Ag NPs have been loaded on thermally exfoliated carbon nitride with the aim to form 5 wt% Ag/C3N4 nanocomposites. Further their photocatalytic activity was tested towards Indigo carmine dye (IC) under 416 nm visible LED irradiation. The results show that each method a) loaded different amount and size of Ag NPs on the surface of C3N4, b) changed optoelectronic behaviors of final nanocomposites and c) significantly influenced their photocatalytic activity.
