Metal ion (Ca2+, Mg2+, Zn2+) catalyzed synthesis of high-quality zeolite templated carbon

Abstract

© 2022 Elsevier Inc.Three metal ions (Ca2+, Mg2+, and Zn2+) were found to be successful catalysts to produce high-quality zeolite templated carbon (ZTC), a periodic three-dimensional graphene-like carbon with ordered microporous structure. Their roles in high-quality ZTC formation were studied by characterizing chemical component, surface morphology, structure, and pore properties. Ca2+, Mg2+, and Zn2+ minimize or eliminate the blockage of channels by carbon deposits and non-selective thermal deposition on the external surface of the zeolite particles. The growth temperature was lowered to only 450 °C. Moreover, the formation mechanism of ordered ZTC structure was revealed for the first time.
