Surfactant-assisted hydrothermal crystallization of nanostructured lithium metasilicate (Li2SiO3) hollow spheres: II—Textural analysis and CO2–H2O sorption evaluation

CO2 chemisorption in Li2CuO2 microstructurally modified by ball milling: study performed with different physicochemical CO2 capture conditions

“…As can be seen, the Li 2 CuO 2 structure was preserved in all the ball milled samples; however, the corresponding diffraction peaks became broader than those observed for the solid-state sample. Hence, these Li 2 CuO 2 microstructural variations are expected to induce important improvements in the CO 2 chemisorption process, as has been reported in previous papers for other lithium and sodium ceramics, [25][26][27][28][29][30][31]37 where the CO 2 chemisorption is importantly related to the particle size and surface area. The crystal size of the solid state sample was measured; however, it was larger than 500 A, which exceeds the detection limit.…”

“…[26][27][28][29][30][31] Based on these results, it is clearly evident that the microstructural changes have important inuence at low and moderate temperatures during the CO 2 capture process in Li 2 CuO 2 . On the other hand, at high temperatures, the CO 2 chemisorption observed on the ball milled sample was not as high as that on the Li 2 CuO 2 solid state sample.…”

“…These materials can be separated by their exhibited temperature CO 2 capture ranges as low (<100 C), moderate (100 to 400 C) or high (>400 C) temperature captors. [25][26][27][28][29][30][31] For example, lithium orthosilicate (Li 4 SiO 4 ) and metasilicate (Li 2 SiO 3 ) have been synthesized by ball milling 30 and hydrothermal 26 techniques, respectively. These materials present some of the previously mentioned ideal properties.…”

Synthesis of LiFePO4/Li2SiO3/reduced Graphene Oxide (rGO) Composite via Hydrothermal Method

“…Figure 2 shows the FTIR spectra of LiFePO 4 [11]. The peak at wavenumber 857 cm -1 corresponds to vibration of Li 2 SiO 3 [12]. Meanwhile, the bands that relate to rGO did not appear due to the low concentration of rGO in the LiFePO 4 /Li 2 SiO 3 /rGO composite.…”

A facile approach to fabricate Li4SiO4 ceramic pebbles as tritium breeding materials

“…However, it is still a great challenge to develop a facile route for the fabrication of satisfactory Li 4 SiO 4 ceramic pebbles (with small grain size, high phase purity, abundant porosity and high crush load, etc.). Hydrothermal method offers many advantages over conventional and non-conventional ceramic synthetic methods [9], and it has been employed to synthesize LiAlO 2 , Li 2 SiO 3 and Li 2 TiO 3 powders [10][11][12][13]. To the best of our knowledge, few relevant reports about hydrothermal method for the fabrication of Li 4 SiO 4 ceramic pebbles have been reported.…”
