摘要：

Special shaped (deformable) hollow g-C3N4 nanospheres were synthesized by the solvothermal technique using silica spheres as template. The X-ray diffraction (XRD) peaks of the product were indexed to g-C3N4 materials. Field-Emission Scanning Electron Microscopy and Transmission Electron Microscopy confirmed that the external diameter of the hollow nanospheres is about 130-150 nm and thickness of the wall is about. 20-30 nm. The FTIR spectrum showed absorption peak at 810 cm(-1) can be attributed to the s-triazine (C3N3) breathing mode. Raman spectrum exhibited two broad peaks approximately at 1360 cm(-1) (D band) and 1580 cm(-1) (C band). The deformed pie shape or mortars like hollow spheres were first reported. The flexility of the deformable hollow g-C3N4 nanospheres may be used in special field such as drug delivery carriers adjusting the delivery ratio by the external pressure, and a good material for studying the mechanical Properties of the sp(2) hybrid g-C3N4. The photoluminescence spectrum of the product indicates that the deformable hollow g-C3N4 nanospheres may have potential applications in nano-optical device fields. (C) 2011 Elsevier B.V.
