Abstract

Li4SiO4 is a promising material for CO2 capture at high temperatures. A high capture capacity up to 36.7 wt% between 450 and 700 °C, fast carbonation/decarbonation kinetics, good mechanical properties, and also cyclic usage can be counted as the advantages of this solid. Li4SiO4 can be synthesized using different methods: the solid-state reaction, the precipitation method, the impregnation suspension method, and the sol–gel method. However, all the processes which are mentioned above requires high energy consumption and result in products having a large grain size. Combustion synthesis techniques are energy-efficient and advantageous in terms of obtaining nano-sized ceramic powders. Therefore, the main purpose of this study is producing Li4SiO4 powders with volume combustion synthesis (VCS) available to use as a high temperature sorbent in CO2 capture, instead of the conventional and commercial methods.
