Acidity and porosity properties of zeolites affect their catalytic performance in thymol synthesis Open
Thymol is synthesized from m-cresol alkylation reaction with 2-propanol. A few commercial zeolites have been tested in this reaction, but the influence of acidity and porosity of a zeolite on the m-cresol conversion and thymol yield is sca…

Lewis acid zeolite catalysts via chemical modification of extra-large pore germanosilicates Open
Lewis acid zeolites containing tetravalent metals, such as Sn or Zr, are of great interest as catalysts for variousreactions owing to their tunability, activity, and reusability. In the context of emerging trends in biomass-relatedsubstrat…
Selective Oxidation of Citronellol over Titanosilicate Catalysts Open
Citronellol is one of the most widely used fragrances for bouquetting purposes and it is a starting material for synthesis of several other terpenoids. Nevertheless, few data have been reported on citronellol selective oxidation. According…

Incorporation of Ti as a Pyramidal Framework Site in the Mono‐Layered MCM‐56 Zeolite and its Oxidation Activity Open
MWW zeolite MCM‐56 with Al atoms on the surface was functionalized with Ti to produce pyramidal TiOH groups. This was carried out by removal of Al with nitric acid, calcination and treatment with titanium diisopropoxide bis(acetylacetonate…
From 3D to 2D zeolite catalytic materials Open
Research activities and recent developments in the area of three-dimensional zeolites and their two-dimensional analogues are reviewed.
Accessibility enhancement of TS-1-based catalysts for improving the epoxidation of plant oil-derived substrates Open
TS-1-based catalysts with different textural features, namely layered TS-1, pillared TS-1, and Ti-pillared TS-1 as well as mesoporous TS-1, were investigated in the liquid-phase epoxidation of methyl oleate as a model compound for plant oi…
Selective oxidation of bulky organic sulphides over layered titanosilicate catalysts Open
Selective oxidation of sulphides is a straightforward method of preparation of organic sulphoxides and sulphones. Bulky sulphides can be selectively oxidized using layered crystalline titanosilicate catalysts with H2O2as the oxidant.
