Reactive gas environment induced structural modification of noble-transition metal alloy nanoparticles.
Noble-transition metal (noble=Pt,Au; transition=Co,Ni,Cu) alloy particles with sizes of about 5 nm have been studied by in situ high-energy x-ray diffraction while subjected to oxidizing (O(2)) and reducing (H(2)) gas atmospheres at elevated temperatures. The different gas atmospheres do not affect substantially the random alloy, face-centered-cubic structure type of the particles but do affect...
متن کاملNoble-transition metal nanoparticle breathing in a reactive gas atmosphere.
In situ high-energy X-ray diffraction coupled to atomic pair distribution function analysis is used to obtain fundamental insight into the effect of the reactive gas environment on the atomic-scale structure of metallic particles less than 10 nm in size. To substantiate our recent discovery we investigate a wide range of noble-transition metal nanoparticles and confirm that they expand and cont...
متن کاملContinuous pressure-induced structural transition in the noble-metal halide melts.
The reduction of the charge of the species in molten salts, including the complete removal of the Coulomb interaction, appears to have the same eFect as an increase in the pressure on these systems. This observation leads to the prediction that a continuous pressure-induced structural change is to be found in the noble-metal halide melts at much lower pressures than those used to induce a simil...
متن کاملVisible fluorescence induced by the metal semiconductor transition in composites of carbon nanotubes with noble metal nanoparticles.
We show that single-walled carbon nanotube (SWNT) bundles emit visible fluorescence in the presence of noble metal nanoparticles and nanorods in the solid state. Conductivity measurements with metallic nanotubes, isolated from pristine SWNTs, show that they become semiconducting in the presence of the metal nanoparticles. Nanoparticle binding increases the defects in the nanotube structures whi...
متن کاملExotic species with explicit noble metal-noble gas-noble metal linkages.
We present a study of the isoelectronic Pt2Ng2F4 and [Au2Ng2F4]2+ species with noble gas atoms (Ng = Kr, Xe, Rn) acting as links bridging the two noble metal atoms. The stability of the species is investigated using several thermodynamic, kinetic and reactivity indicators. The results are compared against [AuXe4]2+, which is thermodynamically unstable in the gas phase but is stabilized in the s...
