“…(4)] between ZrO 2 and LiOH does not seem to have completed, when tetrapropyl ammonium hydroxide and acetic acid were used as hydrolyzing agents or it could be due to complete reaction between the lithium zirconate and CO 2 [Eq. (5)] presented in the atmosphere to form lithium zirconate [5].…”

“…Liquid-phase methods have also been proposed to synthesize lithium zirconate, in which soluble inorganic Zr and Li compounds were used as precursors to obtain a complex solution, which was then dried to form lithium zirconate [5]. Synthesis of pure and homogeneous nanocrystalline ceramic powders from organic precursors is an attractive route.…”

Li 2 CuO 2 was used for the CO 2 chemisorption process. Li 2 CuO 2 was thermally treated under a flux of CO 2 , dynamically (from 25 to 1000 C) and isothermically. The results clearly showed that Li 2 CuO 2 is able to chemisorb CO 2 in a wider range of temperatures than those presented by other lithium ceramics. Therefore, this ceramic may become a new option as CO 2 captor.In the last ten years, some lithium ceramics have been proposed as possible CO 2 captors because of the chemisorption process produced between CO 2 and lithium atoms present in the ceramic structure.1-5 Some of the ceramics proposed up to now are; lithium oxide (Li 2 O), lithium zirconates (Li 2 ZrO 3 and Li 6 Zr 2 O 6 ), lithium orthosilicate (Li 4 SiO 4 ), and lithium orthotitanate (Li 4 TiO 4 ). [6][7][8][9][10][11][12][13] In general, all these materials show a similar chemisorption mechanism. First, CO 2 reacts over the ceramic particle surface, producing a lithium carbonate (Li 2 CO 3 ) external shell and the corresponding residual oxide. Then, in order to continue the CO 2 chemisorption, lithium atoms have to diffuse from the core of the particles toward the surface to complete the reaction. 6 Additionally, it has been proposed that one of the most important steps, and perhaps the limiting one, of the whole process is the diffusion. On the other hand, lithium cuprate (Li 2 CuO 2 ) has been used for different electrical applications such as cathodes for lithium batteries and as a superconductor material, owing to the excellent lithium diffusion.14-19 The high lithium diffusion and structural characteristics have been reported for Li 2 CuO 2 ; therefore, the aim of the work reported here was to study and demonstrate whether or not Li 2 CuO 2 is able to capture CO 2 , by a mechanism similar to that reported previously for other lithium ceramics.Li 2 CuO 2 sample was obtained by a coprecipitation method using 10 wt % excess of lithium, and its diffractogram is shown in Figure 1. Li 2 CuO 2 was the main phase, and only small quantities of copper oxide (CuO) were detected. The presence of CuO indicates that excess lithium was not enough to complete the reaction. However, the volume fraction of this phase should not exceed 5% of the total system, and as CuO does not capture CO 2 , it would not interfere with the CO 2 capture analysis. The same figure shows the morphology of the Li 2 CuO 2 particles. As can be seen, the particles presented a dense polyhedral shape, with a particle size distribution of 11 AE 2 mm. Additionally, the particles presented some kind of texture; the surface of the particles seems to be corrugated. This kind of morphology and particle size are similar to those obtained for other lithium ceramics that have been tested as CO 2 captors. It could be useful for comparison reasons.Once Li 2 CuO 2 was characterized, the material was thermally treated under a CO 2 stream to analyze whether or not this material is able to act as a CO 2 captor. If Li 2 CuO 2 traps chemically CO 2 , the following reaction may occur (reaction 1):...
