酸化法制备g-C3N4纳米片及其光催化性能研究
Preparation and Photocatalytic Activity of g-C3N4Nanosheets by Acidification
摘要
Abstract
g-C3N4nanosheets were prepared by ultrasonication assisted nitric acid exfoliation method from bulk g-C3N4(b-CN),which was prepared by thermal polymerization of melamine.The obtained products were characterized by SEM, TEM, XRD and solution adsorption method.And the photocatalytic performance of samples was investigated.The results exhibit that when the concentration of HNO 3was 2 M,the g-C3N4nanosheets(CN-N-2)had a special surface area of 161.2 cm2/mg, and show the best photocatalytic activity.The enhanced photocatalytic performance is attributed to the increased active sites of the nanosheets owing to the increased specific surface area after acid treatment.关键词
