• . Elemental analyses of these materials showed that there was no silica residue after the treatment. Figure 2 shows the nitrogen physisorption isotherms of the SBA-15 and LiNbO3/SBA-15 composite (LN), and the corresponding pore size distributions of the samples. The measurements were recorded to investigate

• samples, nitrogen adsorption–desorption curves show type IV isotherms with hysteresis loops, which is typical for mesoporous solids, suggesting that the ordered structure remains intact after LiNbO3 loading. Furthermore, the isotherms show a significant reduction of the specific BET surface area from 729

• taken into account based on LaB6 reference measurements. Small-angle X-ray diffraction patterns were recorded on a Bruker AXS Nanostar. The nitrogen physisorption isotherms at 77 K were measured using a Quantachrome Autosorb 1C. The samples were pre-treated at 150 °C for 3 h in vacuum (10−6 bar). The
