High-quality single-walled carbon nanotubes (SWCNTs) have been synthesized from H2–CH4 mixtures on a MgO-supported bimetallic Mo/Co catalyst using microwave plasma-enhanced chemical vapor deposition (PECVD). Reaction parameters including temperature, H2:CH4 ratio, plasma power, and synthesis time have been examined to assess their influence on SWCNT synthesis. Raman spectroscopy and high-resolu...

A sp(3)-sp(2) C-C cross-coupling reaction catalyzed by gold in the absence of a sacrificial oxidant is described. Vital to the success of this method is the implementation of a bimetallic catalyst bearing a bis(phosphino)amine ligand. A mechanistic hypothesis is presented, and observable transmetalation, C-Br oxidative addition, and C-C reductive elimination in a model gold complex are shown. W...

germanium nanowires (genws) were synthesized using chemical vapor deposition (cvd) based on vapor–liquid–solid (vls) mechanism with au nanoparticles as catalyst and germanium tetrachloride (gecl4) as a precursor of germanium. au catalysts were deposited on silicon wafer as a thin film, firstly by sputtering technique and secondly by submerging the silicon substrates in au colloidal solution, wh...

The understanding of electrocatalytic activity and poisoning resistance properties Pt Pd nanoparticles, recognized as the best electrocatalysts for ethanol oxidation reaction, is an essential step commercialization direct fuel cells (DEFCs). In this paper, mono bimetallic nanoparticles with different atomic ratios have been synthesized to study their reaction in alkaline solutions. were physioc...

Introduction The integration of fuel processors, the catalytic units that can convert fossil fuels to hydrogen-rich streams, with hydrogen fuel cells is considered as a promising solution to the problems related to the availability, distribution and storage of hydrogen. Recent computer-based studies have demonstrated the possibility of efficient hydrogen production on-board the vehicles through...

Six Co-Rh/Fe3O4 catalysts with different cobalt loadings were prepared by the co-precipitation of RhCl3, Co(NO3)2, and Fe(NO3)3 using Na2CO3 as the precipitant. These catalysts were tested for dicyclopentadiene (DCPD) hydroformylation to monoformyltricyclodecenes (MFTD) and diformyltricyclodecanes (DFTD). The results showed that the MFTD formation rate increased with increasing cobalt loading, ...

Abstract Nickel based nano-catalysts, supported on bimetallic oxide support (i.e. Ni/Al 2 O 3 -MgO) were prepared by the co-precipitation (one step, Catalyst-A) and followed impregnation (two steps, Catalyst-B) techniques separately. The catalysts then tested for dry reforming of methane (DRM) reaction. effect catalyst synthesis technique their performance has been analysed. -MgO nano-catalyst ...

How does bimetallic composition of nickel-rich semiconductors affect their electrochemical water splitting activity?

Bimetallic Fe–Cu MOF was effectively synthesized through a one-pot solvothermal process and successfully characterized by TEM, XPS, SEM, XRD, BET, EDX, elemental mapping, FT-IR analysis. This bimetallic employed as catalyst in the reduction of nitroarenes at room temperature well dyes, for example, methyl orange (MO) methylene blue (MB). Results pointed to exhibiting outstanding catalytic perfo...
