  • carbon
  • Herein, we prepared a 3D interwoven structure with Pd atoms deposited on homogeneously bound MnO 2 nanowires and carbon nanotubes (CNTs) (Pd/MnO 2 -CNT), allowing the combination of superior catalytic performance of atomic Pd incorporated in the metal oxide and the high conductivity of CNT.

  • By making tiny particles of this palladium-carbon-nitrogen material, the scientists were able to show that it catalyses what is known as the Suzuki reaction very efficiently. (phys.org)
  • In chemistry, forming a bond between two carbon atoms is often done using the Suzuki reaction," says Sharon Mitchell, a scientist in Pérez-Ramírez's lab. (phys.org)
  • The dialkylphosphide acts as a nucleophile and attacks electrophilic carbon atoms. (wikipedia.org)
  • Graphene is a crystalline allotrope of carbon in the form of a nearly transparent (to visible light) one atom thick sheet. (wikipedia.org)
  • More than half the supply of palladium and its congener platinum is used in catalytic converters, which convert as much as 90% of the harmful gases in automobile exhaust (hydrocarbons, carbon monoxide, and nitrogen dioxide) into less noxious substances (nitrogen, carbon dioxide and water vapor). (wikipedia.org)
  • molecule
  • The structure helped explain puzzles about ferrocene's conformers, the molecule features an iron atom sandwiched between two parallel cyclopentadienyl rings. (wikipedia.org)
  • The boron atom in this molecule is a key substructure because through it certain proteasomes are blocked that would otherwise degrade proteins. (wikipedia.org)
  • The F2 molecule is commonly described as having exactly one bond (in other words, a bond order of 1) provided by one p electron per atom, as are other halogen X2 molecules. (wikipedia.org)
  • hydrogenation
  • The cluster size of an ensemble of palladium nanoclusters was found to increase on hydrogenation. (esrf.eu)
  • The structural and electronic changes of bulk palladium upon hydrogenation are well documented . (esrf.eu)
  • As hydrogen in a metal can decrease the strength of the host metal bonding, this raises the question of how an ensemble of palladium nanoclusters will interact during and after hydrogenation. (esrf.eu)

  • But palladium has one significant feature-the capability to absorb (dissolve into itself) molecular hydrogen. (wikipedia.org)
  • The high frequency of molecular vibration is a consequence of the small mass of the hydrogen atom as compared to the mass of the oxygen atom and this makes detection of hydroxyl groups by infrared spectroscopy relatively easy. (wikipedia.org)
  • While an individual fluorine atom has one unpaired electron, molecular fluorine (F2) has all the electrons paired. (wikipedia.org)
  • unusual
  • This transition metal dichalcogenide has an unusual monoclinic structure, with pairs of selenium atoms existing as dimers forming layers between palladium atom sheets. (wikipedia.org)
  • The aurophilic interaction is thought to result from electron correlation of the closed-shell components, which is unusual because closed-shell atoms generally have negligible interaction with one another at distances on the scale of the Au-Au bond. (wikipedia.org)
  • catalytic
  • In this way, it is possible for the individual catalytic centres made of iron atoms to be separated from each other by aluminium atoms. (fz-juelich.de)
  • Defects
  • clarification needed] Palladium films with defects produced by alpha particle bombardment at low temperature exhibit superconductivity having Tc=3.2 K. Naturally occurring palladium is composed of seven isotopes, six of which are stable. (wikipedia.org)
  • crystalline
  • 2D Materials, sometimes referred to as single layer materials, are crystalline materials consisting of a single layer of atoms. (wikipedia.org)
  • single
  • Our strategy can be generalized to design new single atom electrocatalysts for numerous functionalities. (rsc.org)
  • It is well known that palladium only delivers the desired product when active centres that are as small as possible are present, approximately in the shape of single palladium atoms in an otherwise inactive matrix. (fz-juelich.de)
  • phases
  • E = E 0 + R T F ln ⁡ a H + ( p H 2 p 0 ) 1 / 2 {\displaystyle E=E^{0}+{RT \over F}\ln {a_{\mathrm {H} ^{+}} \over ({\frac {p_{\mathrm {H} 2}}{p^{0}}})^{1/2}}} When palladium is electrochemically charged by hydrogen, the existence of two phases is manifested by a constant potential of approximately +50 mV compared to the reversible hydrogen electrode. (wikipedia.org)
  • structure
  • We investigated the effect of hydrogen exposure on a palladium cluster assembled film produced with a dual-target dual-laser vaporisation source with three different techniques: X-ray diffraction (XRD), Extended X-ray absorption fine structure (EXAFS) and scanning tunnelling microscopy (STM). (esrf.eu)
  • coordination
  • The average grain size was derived both from the width of the XRD Bragg peaks and the coordination number around Pd atoms obtained from EXAFS, whereas the (lateral) diameter of the nanoclusters at the sample surface was measured directly by STM. (esrf.eu)
