摘要
A facile method for preparing hollow mesoporous carbon nitride microspheres(HMCNMs)has been developed.A cya namide/ethanol solution was used as a precursor,with ethanol acting as both a solve nt and a porogen,to prepare HMCNMs with a high surface area of 112 m^2/g.It was demonstrated that the HMCNM microstructure and surface morphology can be controlled by adjusting the proportion of ethanol in the precursor solution.The resulting HMCNMs exhibited much higher visible light photocatalytic degradative activity toward methylene blue than bulk graphitic carbon nitride.
