Preparation and Properties of Ag@C3N4 Photocatalyst Supported by Hydrogel
Source abstract
Abstract
Graphitic carbon nitride (g-C 3 N 4 ) is widely used in the field of photocatalysis due to its unique two-dimensional planar structure and suitable energy band structure.However, it has some disadvantages such as fast recombination of the electron-hole, low visible-light utilization efficiency and poor dispersion in water, which hinder its application.In this study, the hydrogel prepared by sodium alginate was used as matrix to improve the dispersion of Ag@C 3 N 4 composite in water, and at the same time enhanced the separation efficiency of photoelectron-holes pairs, thus improving its photocatalytic performance.Firstly, g-C 3 N 4 was synthesized by thermal polymerization and then exfoliated into nanosheets by ultrasound.Then, Ag nanoparticles were deposited in situ on the surface of g-C 3 N 4 by solution method to prepare Ag@C 3 N 4 .Finally, hydrogel loaded with Ag@C 3 N 4
