State of the art and perspectives of the CO2 chemisorption in ceramics with its simultaneous or subsequent chemical transformation

Abstract

This short review focuses on presenting the CO2 capture processes performed in ceramic materials at high temperatures, but mainly on its simultaneous or subsequent catalytic conversion to different added-value products. Initially, it is presented a brief introduction, talking about the CO2 pollution problems and its chemical capture processes at moderate and high temperatures. Then, a complete description and discussion is given on the alkali and alkaline-earth ceramics used for subsequent CO2 chemical sorption and catalytic reactions employed for the production of added-value products. This work mainly describes the presence of this ceramics, their evolution into multifunctional systems implying the CO2 chemical transformation and possible prospects on ceramics used within the same framework.
