Porous Graphitic Carbon Nitride Synthesized via Using Carbon Nanotube as a Novel Recyclable Hard Template for Efficient Visible Light Photocatalytic Organic Pollutant Degradation

摘要

Two-dimensional (2D) graphitic carbon nitride (g-C3N4) has attracted considerable attention due to its many intriguing properties in visible light photocatalysis. However, the photo- catalytic performance of g-C3N4 is far from satisfaction partly because standard synthesis methods prepare rather dense materials with low specific surface area. Herein, we report a facile approach to prepare porous g-C3N4 via using carbon nanotubes (CNT) as a novel hard template for the first time. Unlike other hard templates, CNT can be easily removed by ultrasonic method and recycled to produce porous g-C3N4.
