Article Description

Exfoliating bulk g-CN into its nanosheets attracts great interests due to their amazing application in photocatalytic area, especially supported with silver nanoparticles (Ag NPs). Herein, a facile acid-assisted method was firstly developed to exfoliate the bulk g-CN into g-CN nanosheets using concentrated hydrochloric acid. Ag NPs with average diameter of ∼40 nm were coated into g-CN nanosheets through electrostatic absorbance effect. By adjusting the feeding ratios between Ag NPs and g-CN, the Ag NPs/g-CN composites with tunable Ag NPs can be achieved. Results illuminate that after coated with Ag NPs, photocatalytic performance of the Ag NPs/g-CN composites is enhanced significantly under visible light irradiation compared with that of the pure g-CN. Furthermore, with an appropriate mass ratio, the Ag NPs/g-CN (6:5) composite exhibits the best photocatalytic activity and favorable stability due to the relatively higher Ag NPs loading.
