摘要：

Carbon cryogels (CCGs) with larger pores having mean pore diameters in the range 14-108 nm were synthesized using a sal-gel process from resorcinol and formaldehyde in carbonate buffer solutions by adjusting the total concentrations and pHs of the catalyst components. Lower CO32- catalyst concentration for larger pore formation could be reproducible considering acid-base equilibrium. The resulting CCGs showed molecular sieving characteristics that were suitable for protein adsorption. (C) 2014 Elsevier B.V. All rights reserved.
