A synthetic water-soluble meso-tetra(2,6-dichloro-3-sulfonatophenyl)porphyrinate of iron(lll) chloride (FeP) was used as biomimetic catalyst in the oxidative coupling of three monomeric phenols (catechol, caffeic, and p-coumaric acids), which are common constituents of natural humic substances. The extent of oxidation induced by the FeP catalyst in solutions of phenolic monomers was followed in...

A novel generic method of silica supported catalyst system generation from a fluid state is presented. The technique is based on the combined flow and radiation (such as microwave, thermal or UV) induced co-assembly of the support and catalyst precursors forming nano-reactors, followed by catalyst precursor decomposition. The transformation from the precursor to supported catalyst oxide state c...

The present research introduces adsorption of sulfonated cobalt phthalocyanine catalyst (Europhtal) from the real wastewater that is produced in mercaptan removal unit (Merox) third refinery, South Pars Gas Complex (SPGC), Assaluyeh, Iran. Therefore, novel low-cost natural zeolite modified with polyaluminium chloride (PAC) was investigated as an adsorbent for treatment Europhtal wastewater. Cen...

The Zeolite Y as a support was modified by the incorporating of Fe and TiO2 in one single step using impregnation method. The synergistic effects between those components enhance the catalytic activity for the degradation of amaranth dye under ultrasonic irradiation with output power of 50 W and 40 kHz frequency. Different characterization techniques were used to elucidate the physical and chem...

This work and a series of successive works aim to subject various ratios of palm olein and palm stearin blends to chemical interesterification under different conditions of catalyst, temperature and time in order to obtain fat blends suitable for the production of vegetable butter (margarine) fortified with different natural vitamins and minerals and prepared by using nanotechnology. In this pa...

Partial oxidation of methane in monolithic catalysts at very short contact times has recently been shown to offer a promising route to convert natural gas into syngas (CO, H2), which can subsequently be converted to higher alkanes or methanol. Detailed models are needed to understand the complex interaction of transport and kinetics occurring in these reactors. In this work, the partial oxidati...

Herein, we use a supramolecular coordination cage as catalyst for the reduction of aldehydes to corresponding alcohols using weak hydride donor in neutral water, with mode action reminiscent natural enzymes.

A multiplexed, microfluidic platform to detect reactive metabolites is described, and its performance is illustrated for compounds metabolized by oxidative and bioconjugation enzymes in multi-enzyme pathways to mimic natural human drug metabolism. The device features four 8-electrode screen printed carbon arrays coated with thin films of DNA, a ruthenium-polyvinylpyridine (RuPVP) catalyst, and ...

The activity of a Te-MgO catalyst prepared by adsorbing Te vapor onto MgO powder was determined by dehydrogenation of indane, 9,10-dihydrophenanthrene, cumene, and p-cymene. The activity of the Te-MgO catalyst was higher than that of the MgO catalyst in most of the cases investigated. The selectivity of the former catalyst was much higher than that of the later in all cases studied. The Te-MgO ...

Catalytic therapy (CT) is a cancer treatment modality based on the generation of reactive oxygen species (ROS) using a combination of substrate molecules and a catalyst. The most frequently used substrate/catalyst pair is ascorbate/Co phthalocyanine (PcCo). In the present work, herb extracts containing pigments have been studied as a catalyst in place of PcCo. Extracts from herbs are expected t...
