Synthesis, characterization and catalytic application for ethylbenzene dehydrogenation of an iron pillared clay

Pillared laponite clay-based Fe nanocomposites as heterogeneous catalysts for photo-Fenton degradation of acid black 1

“…Upon calcinations at a high temperature, the intercalated species undergo dehydration and dehydroxylation and hence are converted to oxide pillars propping the clay layers apart. The final pillared interlayered clays (PILCs) present a permanent porous network, showing a dramatic improvement in catalytic and adsorption applications (Baksh and Yang, 1992;Li et al, 1997;Mishra and Parida, 1998;Zhu and Lu, 1998;Hao et al, 2003;Huerta et al, 2003).…”

“…Among the intercalated clay precursors indicated above, Fe 3+ is an ongoing one for research in heterogeneous catalysts and adsorption. Several studies on the formation of Fe-PILC were carried out in the past few years Choudary et al, 1997;Yang, 1999, 2000;Huerta et al, 2003). Many researchers showed that the synthesized Fe-PILC, using bentonite and montmorillonite clay, has the basal spacing up to 10-20Å and BET surface area reaching up to 300 m 2 /g.…”

Feasibility Analysis of Some Clays as Adsorbents for Styrene Purification

“…Reactions involving acid sites play an important role not only in alumina deactivation, but also in the reactivity of styrene. This monomer can be acidity activated to form active species by a dealkylation mechanism (benzene formation) [5][6][7] or radical polymerization [8,9]. Therefore a previous study of chemical stability of the pairs styrene-adsorbent is needed in order to find out a cheap adsorbent material more suitable than alumina for styrene purification.…”

Catalytic wet peroxide oxidation of phenol over Ce-Zr-modified clays: Effect of the pillaring method

“…The interaction of the second cationic components with the pillars in the microenvironment of the clay is very crucial for the property of the solid. Indeed, it has been shown that pillared clay with different basal spacing and microporosity was prepared with mixed cation pillaring [3][4][5][6][7]. In addition, previous works [7,8] report that the incorporation of species of Ce favors catalytic activity (CWPO reaction) of the pillared clays, probably because the cerium oxide formed in the solids enhances the textural properties of the solid, the dispersion and/or the redox properties of active species [9,10].…”
