Abstract

Mesoporous silicas MCM-41 with larger and variable pore size were synthesized hydrothermally by using cetyltriethylammonium bromide (CTEAB) which has a larger hydrophilic head-group compared to cetyltrimethylammonium bromide (CTAB) as templating agent. Various factors such as surfactant and silica molar ratio, sodium hydroxide to silica molar ratio, the crystalization time, the amount of H2O on the pore structural properties of samples were investigated.

The experimental results showed that mesoporous silicas MCM-41 with a different pore diameter in the range of 4–7 nm can be obtained by adjusting surfactant and silica molar ratio. CTEAB is an effective templating agent for large pore diameter (>4 nm) of mesoporous silicas MCM-41. The MCM-41 pore structure properties did not change markedly when the amount of H2O increase in the range investigated in the paper.

Kurzfassung

Mesoporöse Silika-Materialien MCM-41 mit größerer und variabler Porengröße wurden hydrothermal synthetisiert unter Verwendung von Cetyltriethylammoniumbromid (CTEAB) als Templat. Dieses hat im Vergleich zu Cetyltrimethylammoniumbromid (CTAB) eine größere hydrophile Kopfgruppe. Es wurden verschiedene Parameter wie das molare Verhältnis von Tensid zu Silika, von Natriumhydroxid zu Silika, die Kristallisationszeit, sowie der H2O-Anteil auf die Porenstruktureigenschaften der Proben untersucht.

Die experimentellen Ergebnisse zeigen, daß durch Einstellung des molaren Verhältnisses von Tensid zu Silika mesoporöses Silika MCM-41 mit verschiedenen Porendurchmesser im Bereich von 4–7 nm erhalten wird. CTEAB ist dabei ein effektives Templat zur Erhöhung des Porendurchmessers (>4 nm) von mesoporösen Silika MCM-41. Die Porenstruktureigenschaften von MCM-41 werden offensichtlich nicht durch eine Erhöhung des H2O-Anteils im untersuchten Bereich beeinflußt.
