the world is currently fa.ing the cha.lenges of globa. wa.ming a.d clima.e cha.ge. Numerous efforts ha.e been ta.en to mitiga.e CO2 emission, a.ong which is the use of solid sorbents for CO2 ca.ture. In this work, Li4SiO4 wa. synthesised via.a.sol-gel method using lithium nitra.e （LiNO3） a.d tetra.thylorthosilica.e （SiC8h20O4） a. precursors. a.pa.a.etric study of Li：Si mola. ra.io （1-5）, ca.cina.ion tempera.ure （600-800℃） a.d ca.cina.ion time （1-8 h） were conducted during sorbent synthesis. Ca.cina.ion tempera.ure （700-800℃） a.d ca.bona.ion tempera.ure （500-700℃） during CO2 sorption a.tivity were a.so va.ied to confirm the optimum opera.ing tempera.ure. Sorbent with.the highest CO2 sorption ca.a.ity wa. fina.ly introduced to severa. cyclic tests to study the dura.ility of the sorbent through 10 cycles of CO2 sorption-desorption test. the results showed th.t the ca.cina.ion tempera.ure of 800℃ a.d ca.bona.ion tempera.ure of 700℃ were the best opera.ing tempera.ures, with CO2 sorption ca.a.ity of 7.95 mmol CO2·（g sorbent）^-1 （93% of the theoretica. yield）. throughout the ten cyclic processes, CO2 sorption ca.a.ity of the sorbent ha. dropped a.proxima.ely 16.2% from the first to the tenth cycle, which wa. a.rea.ona.le decline. thus, it wa. concluded th.t Li4SiO4 is a.potentia. CO2 solid sorbent for high.tempera.ure CO2 ca.ture a.tivity.
