Transition metals have long been used as catalysts in the form of dispersions stabilized on inorganic substrates such as silica gel, alumina, and activated charcoal.1 More recently, colloidal platinum nanoparticles have been used as catalysts and photocatalysts in solutions.2 Aqueous colloidal platinum particles are mostly prepared by the reduction of a platinum salt by hydrogen, photochemical,...

It is crucial but challenging to reduce the required noble-metal loading without compromising catalytic performance of oxygen evolution reaction (OER) catalysts. This study presents a highly active OER catalyst composed IrO2 with Ir rich surface (IrO2@Ir) nanoparticles supported over nano TiN coated TiOxNy (IrO2@Ir/TiN). The present approach demonstrates superior catalysts high activity through...

The potential of carbon nanotubes (CNT) supported cobalt catalysts for Fischer-Tropsch (FT) reaction is shown. Using the wet impregnation method cobalt on carbon nanotubes catalysts were prepared with cobalt loading varying from 15 to 45 wt. %. The catalysts are characterized by different methods including: BET physisorption, X-ray diffraction, hydrogen chemisorption, and temperature-progra...

The production of fuels from sunlight represents one of the main challenges in the development of a sustainable energy system. Hydrogen is the simplest fuel to produce and although platinum and other noble metals are efficient catalysts for photoelectrochemical hydrogen evolution, earth-abundant alternatives are needed for large-scale use. We show that bioinspired molecular clusters based on mo...

The results of studies on the separation of platinum(IV) ions by solvent extraction from aqueous solutions after leaching of spent catalysts have been reviewed. The following processes have been discussed: acid leaching of spent catalysts and solvent extraction of platinum(IV) ions by using organophosphorous acids, amines and oximes as the extractants. In hydrometallurgical leaching of spent au...

Samples taken during deuteration of methyl linoleate with the title catalysts were separated into saturate, monoene and diene fractions. Monoenes were further separated into cis and trans fractions. A comparison of the double bond distribution in monoenes with those from hydrogenation of alkaliconjugated !inoleate indicated that up to 59% of the !inoleate was reduced through a conjugated interm...

Automotive exhaust is one of the main generators of air pollutants. This problem is expected to worsen as the demand for privately owned vehicles increases. Internal combustion engines utilizing gasoline and diesel generate harmful pollutants such as nitrogen oxides (NOx), carbon monoxide (CO), unburned hydrocarbons (HC), particulates, and sulfur oxides (SOx). Liquefied petroleum gas (LPG), an ...
