Synthesen und Anwendungen von übergangsmetallhaltigen mesoporösen Molekularsieben

Abstract: Mesoporöse Materialien auf Silicat‐Basis wurden erstmals in den frühen neunziger Jahren bei Mobil untersucht. Diese Verbindungen wiesen Porengrößen zwischen 20 und 500 Å sowie spezifische Oberflächen von bis zu 1500 m2 g−1 auf und wurden nach einem neuartigen Flüssigkristalltemplatansatz hergestellt. Die Methode wurde auf die Synthese mesoporöser Übergangsmetalloxide ausgedehnt, die wegen ihrer variablen Oxidationsstufen und besetzten d‐Bänder – Eigenschaften, die Silicate nicht aufweisen – als Katalysatoren s… Show more

“…They exhibit useful and unusual properties compared to conventional polycrystalline materials. A wide variety of applications such as hydrogen storage [1][2][3], catalysts [4][5][6], coating materials and wear resistance [7,8], dye and pigment [9,10], advanced colorants [11], digital recording system [12], solar energy application [13], wear resistance materials [12], photonic and electronic devices and drug delivery [14,15]. Various techniques have been developed to synthesize Cr 2 O 3 nanoparticles such as hydrothermal [16], solid thermal decomposition [17], bio-method [18], combustion [19], nanocasting method [20], sol-gel [21], precipitation-gelation [22], oxidation of chromium in oxygen [23], laser induced deposition [24], mechanochemical reaction and subsequent heat treatment [25] and sonochemical methods [26].…”
