Oxidative Destruction of Hydrocarbons on a New Zeolite-like Crystal of Ca12Al10Si4O35 Including O2- and O22- Radicals
Source abstract
Abstract
To develop a nonmetal catalyst to decompose hydrocarbons, a new zeolite-like Ca 12 Al 10 Si 4 O 35 was prepared by calcining hydrogarnet, Ca 3 Al 2 (SiO 4 ) 0.8 (OH) 8.8, a hydrothermal reaction product from a mixture of CaO, Al 2 O 3 sol, and amorphous SiO 2 . The X-ray diffraction analysis showed the framework of (Al,Si)O 4 tetrahedra formed in the Ca 12 Al 10 Si 4 O 35 crystal. ESR measurement and Raman spectroscopy revealed that both superoxide anions (O 2 - ) and peroxide species (O 2 2 - ) existed in the cavity of the framework. Due to the O 2 - and O 2 2 - species present, Ca 12 Al 10 Si 4 O 35 exhibited high activity for the oxidation of hydrocarbons to carbon oxides (CO 2 and CO) and H 2 O at >400 °C.
