Abstract

Abstract : A novel recyclable template was used to prepare mesoporous polymeric carbon nitride with prominently increased specific surface area and photoactivity. Abstract : Recyclable template synthesis of polymeric carbon nitride (CN) is rarely reported. Herein, for the first time, octamethyl polyhedral oligomeric silsesquioxane (mPOSS) was used as a recyclable soft template to prepare mesoporous CN with increased specific surface area, photoabsorption, charge separation efficiency, and photocatalytic H2 evolution rate which is ∼4.5 times that of the bulk CN. mPOSS exhibits high stability and recoverability. This work opens an avenue for recyclable template synthesis of mesoporous CN and may advance its industrial application.
