Geopolymers (GPs) are versatile materials that have low intrinsic porosity. This characteristic can be used as a motivator for the development of porous GPs, since separation processes require adsorbents with a high specific area. Thus, this work aimed to elucidate how acid attack and calcination affect the microstructure of GPs. For this purpose, a GP was exposed to H2SO4and 200 °C, being later characterized in terms of morphology, mineralogy, functional groups, and textural properties. Acid etching and calcination proved to be effective strategies for surface area improvement, making the modified GP a strong candidate for use as an adsorbent. |
