A novel multi-molecular catalysis for CO2 decomposition

The CO2 decomposition is needed high temperature in conventional methods. Our aim is to reduce the CO2 decomposition temperature. In this view multi-molecular catalysis is essential. It is achieved through Multiple catalytic sites. The Multiple catalytic sites are created through a novel intercrossing framework catalyst. The intercrossing framework is created between MgO framework and AlPO4 framework by the template (TPAOH). The catalyst has multiple acidic sites on superoxide ion, oxyanion, octahedral Al3+ and Mg2+. The intercrossing frameworks is achieved in first time and the material is named as Kankarlite-2. The active sites and intercrossed framework are confirmed in the crystal structure drawn by XRD data. The surface area is 60m2/g and pore volume is 2.9cm3/g. The TGA and TEM analysis are the supportive evidence for the intercrossing of the two frameworks. Though the surface area and pore volume is low, the activity is too high due to the intercrossing framework. The effective catalytic activity at lower temperature may be due to the cooperative effect of such multiple active sites which leads to the multi-molecular assembling of CO2 molecules. This assembling reduces the CO2 decomposition temperature (63%). The multi-molecular assembling is calculated by a new formula of P n = R mT/(W t) Thus we have achieved intercrossing framework catalyst and multi-molecular catalysis for Carbon capturing at lower temperature.
