Onto Hybrid Organic-inorganic Mesoporous Materials
Based on MCM-41 mesoporous silica, three different hybrid organic-inorganic mesoporous materials were synthesized. Functionalization and hydrophobization of MCM-41 with 3-aminopropyltriethoxysilane (APTES), chlorotrimethylsila-ne (CTMS), and propyltrimethoxysilane (PTMS) were carried out by post-syn...
