A Synthetic Route For The Preparation Of Surface Hydroxylated Ccto The crystal structure of ccto shown in fig. 8 can be obtained from the ideal cubic perovskite structure by superimposing a body centered ordering of ca 2 and cu 2 ions share in a site . the size difference between ca 2 and cu 2 causes the tio 6 octahedra to undergo remarkable tilting, leading to a body centered cubic supercell of space. In the cu k edge xanes (figure 7), the cacu 3 ti 4 o 12 samples and the standard cuo all comprise of square planer cu(ii) species and contain 5 notable features. the dipole forbidden 1s→3d.
A Synthetic Route For Obtaining Ccto Nanoparticles B Illustration Of The pure phase of cacu3ti4o12 (ccto) powder can be successfully synthesized by the sol–gel process. ccto ceramic samples were synthesized at different sintering temperatures of 1015 and 1050 °c. Moreover, the doublet peaks located at 1400 and 1495 cm −1 are attributed to the symmetric and asymmetric o c o stretching of m co 3 2− , [30] and while the peak at ≈1647 cm −1 corresponds. The effects of la 3 doped in calcium copper titanate (ccto) at ca 2 site and cu 2 site were examined by huang et al. 67 the doped compositions, la 0.1 ca 0.85 cu 3 ti 4 o 12 (lccto) ceramics and cala 0.1 cu 2.85 ti 4 o 12 (clcto) ceramics were prepared by the solid state method. ceramics were prepared under sintering temperatures ranging. In addition, due to the prominent structure of ccto with ca 2 and cu 2 atoms of different ionic radii sharing the a sites, which makes ccto also have good photoluminescent and photocatalytic properties, especially in visible light, ccto is proved to be an efficient solar energy conversion photoanode [55], as shown in fig. 4 (b).
