The world is currently facing the challenges of global warming and climate change. Numerous efforts have been taken to mitigate CO

emission

among which is the use of solid sorbents for CO

capture. In this work

Li

SiO

was synthesised via a sol-gel method using lithium nitrate (LiNO

) and tetraethylorthosilicate (SiC

) as precursors. A parametric study of Li:Si molar ratio (1-5)

calcination temperature (600-800℃) and calcination time (1-8 h) were conducted during sorbent synthesis. Calcination temperature (700-800℃) and carbonation temperature (500-700℃) during CO

sorption activity were also varied to confirm the optimum operating temperature. Sorbent with the highest CO

sorption capacity was finally introduced to several cyclic tests to study the durability of the sorbent through 10 cycles of CO

2

sorption-desorption test. The results showed that the calcination temperature of 800℃ and carbonation temperature of 700℃ were the best operating temperatures

with CO

(93% of the theoretical yield). Throughout the ten cyclic processes

CO

sorption capacity of the sorbent had dropped approximately 16.2% from the first to the tenth cycle

which was a reasonable decline. Thus

it was concluded that Li

is a potential CO

solid sorbent for high temperature CO
