摘要：

This paper describes a facile and simple method to prepare g-C3N4 photocalysts by directly heating the protonated melamine precursor. The morphologies of g-C3N4 can be easily adjusted by the heating rate. The g-C3N4 nanotubes were formed when the heating rate is 5 degrees C min (1), and g-C3N4 nanofalkes were obtained with the heating rate of 10 degrees C min (1). All the samples exhibit high specific surface area and narrow pore size distribution, and they exhibit superior photocatalytic properties. The aqueous RhB solution can be completely degraded after the irradiation time of 180 min under visible light irradiation. (C) 2017 Elsevier B.V. All rights reserved.
