Facile one step method realizing scalable production of g-C3N4 nanosheets and study of their photocatalytic H2 evolution activity

Author affiliations

Abstract

Graphene-like g-C3N4 nanosheets show great potential application in varied fields owing to their unique electronic and optical properties. However, most of the developed methods for preparing g-C3N4 nanosheets still suffer from low-yield and time-consuming shortcomings, which considerably hamper their further study and application. Herein, a facile dicyandiamide-blowing method with NH4Cl as the gas template for the synergic achievement of large-quantity and high-quality graphene-like g-C3N4 nanosheets has been reported. The g-C3N4 nanosheets prepared by this one step method possess enhanced specific area surface, improved electron transport ability and increased lifetime of photoexcited charge carriers, revealing enhanced photocatalytic H2 activities than that of bulk g-C3N4. Our work represents a significant progress for the scalable fabrication of high quality 2D g-C3N4 and provides a new pathway for the scalable production of other 2D nanomaterials.
