A novel highly ordered three dimensional cage type mesoporous carbon nitride material (MCN-2 - CN nanocage) with very high surface area and pore volume has been prepared for the first time using three dimensional cage type mesoporous silica, SBA-16 as a template through a simple polymerization reaction between ethylenediamine and carbon tetrachloride. The material has been unambiguously characterized by various sophisticated techniques such as XRD, nitrogen adsorption, HRTEM, EELS, XPS, 13C DD-MAS, and FT-IR spectroscopy. The XRD result reveals that MCN-2 possesses three dimensional structure with a Im3m space group. The specific surface area and pore volume of MCN-2 are significantly higher as compared to those of the template and MCN-1. Because of the excellent textural characteristic and cage type three dimensional porous structure, we believe that the MCN-2 could offer great potential for the applications, such as catalytic supports, gas storage, lubricants, biomolecule adsorption and drug delivery.
