Proton incorporation into the lithium titanate structure decreases the parameter ac of the pseudocubic unit cell from 8.28 Å in Li2TiO3 to ≈ 8.15Å in H2TiO3. Metatitanic acid, like hydrous titania, has weak acid properties, but unlike titania, it sorbs hydrolyzable multicharged cations from aqueous solutions Полный текст |
