Porous geopolymer production and characterisation

Abstract

Porous geopolymers can find application in various areas including heat insulation as well as filtration and catalysis. They are environmentally friendly materials as no substantial energy is needed in order to produce them. In this study, porous geopolymers were produced by using vegetable oil and hydrogen peroxide.. Process conditions including the geoplymer composition, the amount of oil and hydrogen peroxide and geopolymerization temperature were examined in order to see their effect on pore amount, size and morphology. We found that porous geoplymers with density values < 0.2 g/cm3 and with total porosity of > 80% can be prepared by this method. Interesting pore morphology were resulted and will be reported.
