Organic Polymers as Porogenic Structure Matrices for Mesoporous Alumina and Magnesia
Zimei Chen, Christian Weinberger, Michael Tiemann, Dirk Kuckling
July 31, 2018
Mesoporous alumina and magnesia were prepared using various polymers, poly(ethylene glycol) (PEG), poly(vinyl alcohol) (PVA), poly(N-(2-hydroxypropyl) methacrylamide) (PHPMA), and poly(dimethylacrylamide) (PDMAAm), as porogenic structure matrices. Mesoporous alumina exhibits large Brunauer⁻Emmett⁻Teller (BET) surface areas up to 365 m² g−1, while mesoporous magnesium oxide possesses BET surface areas around 111 m² g−1. Variation of the polymers has little impact on the structural properties of the products. The calcination of the polymer/metal oxide composite materials benefits from the fact that the polymer decomposition is catalyzed by the freshly formed metal oxide.
