摘要：An effective one-pot hydrothermal synthesis method based on suppressed growth strategy was invented to produce mesoporous silica nanoparticles (MSNs). In a TEOS-CTAB-NH4OH-water-formaldehyde system, formaldehyde was used as suppressant which formed a polymer shell on the outer surface of the MSNs to control the particle size to about 30 nm. A nanoporous carbon framework was obtained when precursor was carbonized in N-2 followed by a HF leaching of the silica. The pore size of the carbon was about 30 nm. The mechanism for the synthesis process was described. (C) 2011 Elsevier Inc. All rights reserved.
