Porous carbon nitride microsphere with dimaters ranging from 2 to 6 micrometers were synthesized via chemical vapor deposition in this work. Electron microscope images of the composite show that they have multiwalled innerstructure, which was built by disorderly stacked g-C3N4 curved layers assembled from nitrogen bridges of pyramidal structure, making them porous surfaced. Their mechanical and optical properties were studied with nanoindenter and UV-VIS spectra. It shows that they have good mechanical properties and, compared to carbon nitride synthesized by solvent method, out carbon nitride composite showed relativly broader light absorption band between 400 nm and 600 nm. Also, its visible light degradation of methyl blue was studied, showing its potential as visible light photocatalytic for water purification.
