Synthesis and catalytic application of functional transition metal oxides
… level in all urban and industrial centers. Total catalytic combustion has been considered as an effective and viable approach in controlling environmental emission; however some problems such as the non-availability of catalysts with low cost, high activity and stability in prevailing conditions …

Fabrication of porous metal oxides for catalytic application using templating techniques
Nanostrukturierte Materialien zeichnen sich dadurch aus, dass sie aus sehr kleinen Baueinheiten zusammengesetzt sind. Typischerweise liegt die Grössenordnung dieser Bausteine im Bereich von einigen Nanometern. Ein Nanometer entspricht 10-9 Meter. Dadurch bekommen nanostrukturierte Materialien oft …

Preparation of Novel Carbenes and their Catalytic Application to the Cross-Benzoin, Aza-Benzoin and Stetter Reactions
N-Heterocyclic carbenes (NHCs) derived from bicyclic triazolium salts possessing a fused 6 membered ring were found to induce chemoselectivity in the cross-benzoin between aromatic and aliphatic aldehydes. Use of these catalysts gave rise to predominantly one cross-benzoin product which could be …

Isomeric olefinic periodic mesoporous organosilicas: an emerging class of versatile nanomaterials
… desired function and behaviour in a particular application. The presented research work describes the development, characterization and catalytic application of diastereoisomeric olefinic periodic mesoporous organosilicas (PMOs). PMOs are very unique in their compositional structure. The organic …

Base catalysis by alkali modified zeolites
The development, characterization, and catalytic application of a novel zeolite with solid base properties has been completed. From isopropanol decomposition to acetone and propylene, the acid/base properties of various alkali exchanged, faujasite-type zeolites are explored. It is found that upon …

Exploitation of synergy in oxidation catalysis with bimetallic aluminophosphate catalysts
… aluminophosphate AlPO-5, the potential for catalytic application as either a solidacid or redox catalyst is produced. The bimetallic hydrothermal synthesis produced a phase pure and highly crystalline microporous catalyst which displayed properties not seen in monometallic AlPO-5 materials. …
