Silicoaluminophosphate (SAPO)-Templated Activated Carbons

Li, Yunxiang; Wang,Xia; Thersleff,Thomas; Svensson, Gunnar; Hedin, Niklas

Microporous activated carbon was prepared by depositing and pyrolyzing propylene within the microporous voids of SAPO-37 and subsequently removing the template by a treatment with HCl and NaOH. The carbon had a high surface area and large micropore and ultramicropore volumes. The yield, crystallinity, morphology, and adsorption properties compared well with those of a structurally related zeolite-Ytemplated carbon. No HF was needed to remove the SAPO-37 template in contrast to the zeolite Y template, which could be of industrial importance.
