Abstract:

Bimetallic catalysts are of considerable importance because they possess both high activity and selectivity. Recently, there has been considerable interest in bimetallic catalysts produced by surface organometallic chemistry on metals. A detailed description of the structure and composition at the nanometer level is critical to fully understand the behavior of such catalysts. We have undertaken a study of the microstructure of Rh-Sn/SiO2 bimetallic hydrogenation catalysts.A Rh-Sn precursor was prepared by reacting tetrabutyltin with a silica supported Rh parent catalyst (1 %Rh/SiO2).

Abstract:

Bimetallic nanoparticles of silver (Ag) and gold (Au) were synthesized at room temperature using Curcumin. Reduction process of silver and gold ions with different molar ratios leads to production of different nanostructures including alloys and core-shells. Produced nanoparticles were characterized simultaneously with FTIR, UV/vis. spectroscopy, transmission electron microscopy (TEM), and Energy-dispersive X-ray (EDAX). UV/vis. optical absorption spectra of as synthesized nanoparticles reveals presence of surface palsmon resonance (SPR) of both silver at (425 nm) and gold at (540 nm) with sma

Abstract:

An improved acrylamide sol-gel technique using a microwave oven in order to synthesize bimetallic Rh-Pd particles is reported and discussed. The synthesis of Pd and Rh nanoparticles was carried out separately. The polymerization to form the gel of both Rh and Pd was carried out at 80°C under constant agitations. The method chosen to prepare the Rh and Pd xerogels involved the decomposition of both gels. The process begins by steadily increasing the temperature of the gel inside a microwave oven (from 80°C to 170°C). In order to eliminate the by-products generated during the sol-gel reaction, a

Toluene is extensively used in many industrial products, which needs to be effectively detected by sensitive gas sensors even at low-ppm-level concentrations. Here, NiFe2O4 nano-octahedrons were calcinated from NiFe-bimetallic metal-organic framework (MOFs) octahedrons synthesized by a facile refluxing method. The co-existence of p-Phthalic acid (PTA) and 3,3-diaminobenzidine (DAB) promotes the formation of smooth NiFe-bimetallic MOFs octahedrons. After subsequent thermal treatment, a big weight loss (about 85%) transformed NiFe2O4 nanoparticles (30 nm) into NiFe2O4 porous nano-octahedrons wit

Abstract:

In this research, sensing performance of mono and bimetallic nanophotonics SERS sensors of gold-silver nano-columns for the detection of chlorpyrifos was investigated. For optimum substrates for Gold-silver/nano-column surface-enhanced, Raman scattering (SERS) was achieved with the silicon substrate. By combining the Ag SERS activity with the Au chemical stability and nano-columns Si large field enhancement, the Au-Ag/nano-columns Si substrate revealed perfect reproducibility, homogeneity, sensitivity in addition to chemical stability. The sensors were tested by Atomic force microscope (AFM),

Abstract:

<p>Bimetallic cobalt-containing catalysts supported on alumina have been studied in the Fischer-Tropsch synthesis. It has been shown that a promotion of Co/Al<sub>2</sub>O<sub>3</sub> by iridium leads to dispergation of both metals. It was supposed that the metal dispergation occurred due to M-M interaction with formation of the bimetallic nano-particles of cluster type. These particles have the high catalytic activity, selectivity and stability in the Fischer-Tropsch synthesis. It was observed that by regulation of the process conditions it is possible to obtain

Abstract:

The Ni-Pt bimetallic catalyst supported on nanofilm alumina was prepared by coprecipitation method under the assistance of ultrasonic vibration. The characterization result revealed that the prepared catalyst had a good dispersion with an average particle size around 7nm. The activities of supported catalyst of Ni, Pt and Ni-Pt were compared through using the dehydrogenation of methylcyclohexane (MCH) to produce toluene in Microreactor-Gas Chromatography System (MGCS). The conversion and the selectivity of the Ni-Pt catalyst at 350°C for the dehydrogenation of MCH was 97.0% and 100%, respectiv

Abstract:

In the pursuit of a sustainable and environmentally friendly energy future, water electrolyzers emerge as indispensable players in the landscape of renewable energy storage. At the core of their significance lies the ability to convert surplus renewable energy, such as solar or wind power, into hydrogen - a clean and versatile energy carrier. Through the process of electrolysis, water molecules are split into hydrogen (via Hydrogen evolution reaction, HER) and oxygen (via Oxygen evolution reaction, OER) using electricity, typically derived from renewable sources. However, current hydrogen prod

Abstract:

In this paper, exfoliated graphite supported nanoscale Fe-Cu is synthesized by aqueous-phase reductive method. The effect trichloroethene (TCE) reduction by the supported nanoscale Fe-Cu bimetal is researched in the batch experiments. Kinetics studies show that the reduction of TCE process obeys pseudo-second-order kinetics. The kinetic constants of TCE reduction by supported nano bimetal are measured at different nano Fe0 dosage and Cu content on bimetal in this study. When the dosage of supported nano Fe0 in bimetal with 4wt% Cu is 1.25g/L in reaction solution, the kSA of dechlorination reac

Addition of Re into the binary Pt–Sn catalyst increases electrical performance for ethanol oxidation reaction. Ternary based Pt–Sn–Re/MC (80 : 15 : 05) enhances the performance compared to the mono and bimetallic catalysts in the ethanol oxidation reaction in a membraneless fuel cell.
