Abstract
In this article, novel Ag/g-C3N4/C ternary nanocomposites with leaves-fructification-like architecture were prepared by hydrothermal treatment of the mixture of g-C3 N4 nanosheets, glucose solution and silver nitrate. In order to comparison, a series of nanomaterials including g-C3 N4 nanosheets, binary nanocomposites (g-C3 N4 /C) and ternary nanocomposites (Ag/g-C3 N4 /C) loaded with different amounts of carbon were prepared and characterized in detail. The Ag/g-C3 N4 /C1 nanocomposites showed the highest photocatalytic activity towards degradation of MB. The reason for this was bio-inspired structures effects and the synergistic effect of Ag, g-C3 N4 and carbon, which increased visible-light absorption due to their surface plasmon resonance (SPR) effect of Ag, enhanced adsorption for the MB because of the negatively charged surface of Ag, improved photoinduced electron–hole separation efficiency owing to carbon and bio-inspired structures effects.
