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-C₃N₄ nanosheets, glucose solution and silver nitrate. In order to comparison, a series of nanomaterials including g-C₃N₄ nanosheets, binary nanocomposites (g-C₃N₄/C) and ternary nanocomposites (Ag/g-C₃N₄/C) loaded with different amounts of carbon were prepared and characterized in detail. The Ag/g-C₃N₄/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-C₃N₄ 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.
