Molecular transition metal catalysts offer unique potential for the production of fine chemicals. Chemical processes carried out in the presence of well defined molecular catalysts often only require mild, easily accessible conditions, fewer sacrificial reagents, and can selectively produce a...

Natural-gas fuelled catalytic heaters are commonly used in heating industrial space and remote location operations. Industrial units typically contain platinum that provides methane combustion at lower temperatures than non-catalytic burning. This work aimed to find a cost-efficient alternative...

Fortuitous characterization of the cationic nickel cluster [Ni4(NPtBu3)4][Li3Br4(Et2O)3] led to the rational syntheses and characterization of the mixed-valence low-coordinate cationic nickel cluster: [Ni4(NPtBu3)4]BPh4 and [Ni4(NPtBu3)4]PF6, and subsequently the preparation of the anionic...

Markiewicz, Matthew Eugene Paul
Alcohols are an attractive alternative to hydrogen fuel in fuel cells. They are energy dense, easy to store, transport, and they are readily available. Alkaline fuel cells have several kinetic advantages over acidic fuel cells, but they are sensitive to carbon dioxide. The fuel most studied in...

Mixed-Valence First-Row Metal Clusters for Catalytic Hydrodesulfurization and Hydrodeoxygenation
DownloadFall 2013
Salt metathesis between CoCl2 and [KNPEt3]n provides a new route to the halide-substituted cobalt phosphoranimide cluster [CoCl(NPEt3)]4. This cluster is a useful precursor for the preparation of alkyl-capped cobalt phosphoranimide complexes. The methylated heterocubane [CoMe(NPEt3)]4 was...

A series of phosphoranimide-supported first-row transition metal clusters were prepared, structurally characterized, and investigated for catalytic hydrogenolysis of carbon-heteroatom bonds. Homoleptic heterocubane clusters, as well as two-dimensional bi- and tetranuclear compounds of manganese,...

Recently, considerable research has been conducted into solid-acid catalyzed carbonylation of dimethyl ether (DME) to methyl acetate (MeOAc), which can be further used for the iodine-free production of ethanol or acetic acid. The zeolite mordenite (H-MOR) is known as a potential catalyst but is...

The beneficial feature of the application of natural gas in the automotive industry is the lowest carbon content of any fossil fuel, which results in the lowest CO2 emissions. On the other hand, the concern of atmospheric pollution due to methane emissions from natural-gas vehicles (NGV) engines...

Bimetallicity is known to provide synergistic effects and improve catalytic performance of monometallic counterparts in a variety of applications. Conventional impregnation methods for supported catalyst preparation do not allow for the control of bimetallic nanoparticle structure or size, which...

Empowering the Base Metals: Rational Design of Homogeneous Catalysts for Hydrotreatment, and Reduction of Organic Unsaturates
DownloadFall 2013
Hydrocarbon-soluble, low-coordinate, phosphoranimide-supported complexes of the base metals (iron, cobalt and nickel) were developed and evaluated for a range of stoichiometric and catalytic bond-forming and bond-breaking transformations. An unprecedented family of tetrametallic clusters of Co(I)...
