Characterisation of Supported Catalysts

Adsorption Conformation and Lateral Registry of Cobalt Porphine on Cu(111)

“…Transition metal complexes hold great promise for technological and medical applications such as in photonic and optoelectronic devices, catalysts, and metal-based pharmaceuticals. , For instance, metal ions in these molecules can be tailored such that they bind to a desired biomolecular target acting as a potential therapeutic agent and as a catalyst they offer control over the active site and its selectivity. , Frequently, the applications require the organization of the metal complexes on a solid surface, whereby the interaction between the coordinated metal ion and the surface can drastically affect the functional properties of the complexes themselves. Consequently, a detailed understanding of the interfacial interactions between the complexes and the support is important for the future integration of these molecular systems in functional nanodevices. , Tetrapyrroles, such as metalloporphyrins and metallophthalocyanines, are an important class of metal complexes because of their high stability, structural versatility, promising electronic properties, and tunable molecular functionality. , The adsorption of these molecules on coinage metal surfaces has provided a rich playground for the engineering of complex nanoarchitectures by self-assembly and for understanding the reactivity and electronic structure of metal–organic interfaces. − Moreover, the conformation of the molecule can be altered significantly by the interaction with the metal substrate, thus resulting in changes of the intrinsic molecular properties …”

Studies on Pd/NiFe2O4 catalyzed ligand-free Suzuki reaction in aqueous phase: synthesis of biaryls, terphenyls and polyaryls

“…Efforts have been made to enhance the catalytic activity by the use of various ligands containing nitrogen or sulfur, as well as phosphines, salen and N -heterocyclic carbenes in traditional organic solvents [ 12 – 19 ]. However, the problems associated with catalyst separation, poisoning, and product contamination, have led to researchers investigating heterogeneous routes [ 20 – 21 ]. In the last few decades, more attention has been given to overcome these problems by employing a number of heterogeneous palladium systems, such as palladium supported on a variety of support materials (e.g., carbon, metal oxides, zeolites, clays, polymers, diatomite and graphite oxide) as well as in ionic liquids [ 22 – 32 ].…”

Continuous Flow Preferential Hydrogenation of an Octanal/Octene Mixture Using Cu/Al2O3 Catalysts

“…Catalytic hydrogenation has been one of the most widely studied chemical reactions to date. 1 This is mainly because of its wide range of industrial applications including the commercial production of organic compounds. For example, aldehydes, the primary product from the hydroformylation of alkenes, have very little industrial importance.…”
