Novel large pore cage type mesoporous carbon molecular sieves, carbon nanocage, (CKT) with various pore diameters have been prepared from KIT-5 as inorganic templates synthesized at different temperature. It has been found that the textural parameters of the above mesoporous carbons can be easily tuned by a simple adjustment of the weight ratio of sucrose to KIT-5 mesoporous silica. The specific pore volume and the specific surface area of CKT-3(A) are much higher as compared to CMK-3 mesoporous carbon materials prepared from SBA-15 materials synthesized at different temperature. Adsorption of lysozyme over CKT-3(A) and CKT-3(B) has been studied and the results have been compared with the CMK-3 mesoporous carbons with different pore diameters. CKT-3(A) shows superior lysozyme adsorption capacity as compared to other mesoporous carbon materials such as CMK-3-100 and CMK-3-150.
