Preparation and pore size control of cage type mesoporous carbon materials and their application in protein adsorption

摘要

Large pore cage type novel mesoporous carbons have been synthesized using KIT-5 as inorganic template synthesized at different temperature.It should be noted that the standard procedure to make the mesoporous carbon,CMK-3,using SBA-15 mesoporous silica is not suitable in our case to make a highly ordered materials because of the higher bulk density and lower pore volume of mesoporous silica precursor.Thus,we report here an optimised procedure for the preparation of our novel mesoporous carbon materials.The specific pore volume and the specific surface area of ICY-3 are much higher as compared to CMK-3.Adsorption of lysozyme over ICY materials has also been studied and the results have been compared with CMK-3.Among the mesoporous carbon materials studied,ICY-3(A) shows superior lysozyme adsorption capacity as compared to other mesoporous carbon materials such as CMK-3-100 and CMK-3-150.
