Ag nanocrystals decorated g-C_3N_4/Nafion hybrid membranes: One-step synthesis and photocatalytic performance

摘要

Ag nanocrystals (AgNCs) decorated g-C3N4/Nafion hybrid membranes were synthesized by one-step method. And the nanostructures of as-prepared samples were characterized and analyzed by diverse techniques. The results indicated that AgNCs sized 4-5 nm were highly dispersed on the surface of g-C3N4/Nafion hybrid membranes, which can achieve stronger visible light absorption and higher charge separation efficiency. Due to the synergy effect, AgNCs decorated g-C3N4/Nafion hybrid membranes had excellent photocatalytic activity and good recycling stability in the degradation of Rhodamine B under visible-light irradiation. The possible photocatalytic mechanism of AgNCs decorated g-C3N4/Nafion hybrid membranes was tentatively proposed. (C) 2017 Elsevier B.V. All rights reserved.
