“…The microstructure and textural properties obtained through the surfactant-assisted hydrothermal synthesis route, suggests advantages with respect to the solid state reaction method. These pure and nano-crystalline Li 2 SiO 3 may be suitable to be used for certain applications such as CO 2 absorption [103][104][105]. Today, synthesis of lead-free piezoceramics is of strong interest when looking at a more environmentally friendly option for the fabrication of optical and acoustic devices such as optical wave-guiding and frequency doubling [116][117][118][119][120].…”

“…In general, Li 2 SiO 3 has been synthesized by the conventional solid-state reaction method, and only some chemical routes have been studied such as the sol-gel, microemulsion and combustion methods [103][104][105]. Similar to the case of other alkaline ceramics, it is complicated to prepare lithium ceramics with small particle sizes because of its tendency to sinter or to lose lithium through a sublimation process at high temperatures.…”

“…The mechanism for the destruction and reformation of the crystalline phase of the mixed metal oxides while capturing CO 2 by the formation of metal carbonates is proposed. When the CO 2 is removed, a decomposition of the metal carbonates takes place and the crystalline phase reforms [4,10,12,13,16,22,24,28,31,33]. The capture of carbon dioxide over mixed metal oxides that contain silicon dioxide can be expresses as follows.…”

“…Magnesium and calcium silicates have also been used to capture carbon dioxide [3,11] at pre-combustion conditions. Calcium zirconate has been used to capture carbon dioxide [12] from flue gases at temperatures above 600°C. Lithium oxide, the main metal oxide component in CO 2 adsorbents such as lithium silicate, aluminates and zirconates, has been investigated to capture carbon dioxide at higher temperatures.…”

“…However, most of the time, a mixture of Li 2 SiO 3 , Li 2 Si 2 O 5 , Li 4 SiO 4 , and SiO 2 were obtained [13,15,[18][19][20][21]. On the other hand, the synthesis of nanocrystalline ceramic materials imposes a challenge on the traditional solid state synthesis methods which fail to offer a sufficiently narrow size distribution and desired homogeneity at the nanometer level [22]. However, the hydrothermal synthesis method has an advantage for the production of highly crystalline and pure nanoparticles [23].…”
