Carbon supported nano-sized Pt-Pd and Pt-Co electrocatalysts for proton exchange membrane fuel cells
(2009)Nano-sized Pt-Pd/C and Pt-Co/C electrocatalysts have been synthesized and characterized by an alcohol-reduction process using ethylene glycol as the solvent and Vulcan XC-72R as the supporting material. While the Pt-Pd/C ... -
Continuous mesoporous pd films by electrochemical deposition in nonionic micellar solution
(American Chemical Society, 2017)Mesoporous metals that combine catalytic activity and high surface area can provide more opportunities for electrochemical applications. Various synthetic methods, including hard and soft templating, have been developed ... -
Cyclodextrin functionalized nanofibers via electrospinning
(Bilkent University, 2014)Electrospinning is a commonly studied and widely applied technique for generating nanofibers, with a diameter ranging from several tens of nanometers to a few micrometers. The low-cost, simple set-up, relatively high ... -
Electroless synthesis of 3nm wide alloy nanowires inside Tobacco mosaic virus
(2012)We show that 3nm wide cobaltiron alloy nanowires can be synthesized by simple wet chemical electroless deposition inside tubular Tobacco mosaic virus particles. The method is based on adsorption of Pd(II) ions, formation ... -
First-principles calculations of Pd-terminated symmetrical armchair graphene nanoribbons
(Elsevier, 2013)The effects of Palladium (Pd) termination on the electronic properties of armchair graphene nanoribbons (AGNRs) were calculated by using ab initio calculations. After a geometric optimization process, the electronic band ... -
Mechanochemical activation and patterning of an adhesive surface toward nanoparticle deposition
(American Chemical Society, 2015)Mechanical pulling of adhesive tape creates radicals on the tapes surface. These radicals are capable of reducing metal salts to the corresponding metal nanoparticles. In this way, the mechanically activated tape can be ... -
Methyldecalin hydrocracking over palladium/zeolite-X
(Elsevier Science Ltd, Exeter, United Kingdom, 2000)Hydrocracking of methyldecalin over Pd/REX has been studied with surface sensitive techniques in the critical temperature range 325– 3508C. Results from in situ characterization of adsorbed species, and post-reaction ... -
MnOx-Promoted pdAg alloy nanoparticles for the additive-free dehydrogenation of formic acid at room temperature
(American Chemical Society, 2015)Formic acid (HCOOH) has a great potential as a safe and a convenient hydrogen carrier for fuel cell applications. However, efficient and CO-free hydrogen production through the decomposition of formic acid at low temperatures ... -
Multifunctional electrospun polymeric nanofibrous mats for catalytic reduction, photocatalysis and sensing
(Royal Society of Chemistry, 2017)Fabrication and decoration of flexible Nylon 6,6 polymeric nanofibrous mats for production of multifunctional electrospun material was accomplished via visible light-emitting surface-protected silicon quantum dots (Si QD), ... -
Perfectly absorbing ultra thin interference coatings for hydrogen sensing
(OSA - The Optical Society, 2016)Here we numerically demonstrate a straightforward method for optical detection of hydrogen gas by means of absorption reduction and colorimetric indication. A perfectly absorbing metal-insulator-metal (MIM) thin film ... -
Platinum-palladium loaded polypyrrole film electrodes for the electrooxidation of D-glucose in neutral media
(Elsevier Sequoia SA, Lausanne, Switzerland, 1999)Modified polymer films with metal particles incorporated into the films by electrodeposition are known as possible electrocatalysts for various electrode reactions such as fuel cell applications. This work presents some ... -
Routes of formation and composition of NOx complexes adsorbed on palladium-promoted tungstated zirconia
(2006)Surface species obtained during the adsorption of NO and NO/O2 coadsorption at room temperature on Pd-free (WZ) and Pd-promoted tungstated zirconia (Pd/WZ) are identified by means of in situ FT-IR spectroscopy. The WZ and ... -
Standing mesochannels: mesoporous PdCu films with vertically aligned mesochannels from nonionic micellar solutions
(American Chemical Society, 2018)Mesoporous bimetallic palladium (Pd) alloy films with mesochannels perpendicularly aligned to the substrate are expected to show superior electrocatalytic activity and stability. The perpendicular mesochannels allow small ... -
Sulfur poisoning and regeneration behavior of perovskite-based NO oxidation catalysts
(Springer New York LLC, 2017)SOxuptake and release properties of LaMnO3, Pd/LaMnO3, LaCoO3and Pd/LaCoO3perovskites were investigated via in situ Fourier transform infrared (FTIR) spectroscopy, temperature programmed desorption and X-ray photoelectron ... -
Trimetalic heterogeneous catalyst for dehydrogenation of formic acid with enhanced CO tolerance
