A rapid method of synthesizing the layered titanosilicate JDF-L1

Abstract

A rapid procedure for synthesis of highly crystalline and pure samples of JDF-L1 without using organics are reactants or templates is described and indexation of the powder X-ray diffraction pattern of this phase is presented.

Ion Exchange and Application of Layered Silicate

“…The chemical compositions of Na + -titanosilicate and H + -titanosilicate are shown in Table 1. By combining Na2O, SiO2, TiO2 and weight loss, we obtained an empirical composition for synthetic Na + -titanosilicate of Na4Ti2Si8O22·4H2O, which compares well with those reported previously [3][4][5][6]. H + -titanosilicate, as shown in Fig.…”

“…Kostov-kytin and co-workers [6] also investigated on the phase transition of Na + -titanosilicate during heating at 300-700 o C. However, studies of Na + -titanosilicate are still in the early stage. For industrial applications, in which Na + -titanosilicate is used as a catalytic support, studies on surface chemistry, surface area, and porosity are needed, and on the relations between its surface properties and basic intercalation chemistry.…”

Optimization of mesoporous titanosilicate catalysts for cyclohexene epoxidation via statistically guided synthesis

“…Since their introduction in 1983, various categories, such as microporous [6][7][8], mesoporous [9][10][11][12][13] and layered types [14][15][16][17][18][19], have been synthesized. These target different applications, such as ion exchange [20][21][22][23][24], adsorption [25][26][27][28], membrane separation [29][30][31][32], pillaring templating [33,34] and oxidation catalysis [35][36][37][38].…”

Preparation of Transparent PVC-Titanosilicate Nanocomposites by Interlamellar Silylation of Layered Titanosilicate

“…In particular, a general synthetic strategy was developed during the studies of JDF-L1 (Na 4 Ti 2 Si 8 O 22 Á4H 2 O) by Robert et al [21]. Ferdov et al also reported a convenient preparation of JDF-L1 [22], which contains Na ? -JDF-L1 layers composed of tetrahedral SiO 4 units and square pyramidal TiO 5 polyhedrons [21].…”

“…-JDF-L1 [21]. The titanium in JDF-L1 is five-coordinate and has excellent catalytic ability for oxidation reactions [22]. Each layer is separated by water molecules around an interlayer of Na ?…”
