Palladium thorn clusters as catalysts for electrooxidation of formic acid
Pure palladium thorn clusters were synthesized using the electrodeposition method. The clusters were composed of several thorns growing on one basis. Each thorn was composed of hexahedral units with decreasing sizes. The whole thorn was a single crystal along the <220> direction. The cluster was synthesized by square wave electrodeposition. By changing the deposition factors, a mixture of thorn...
متن کاملHydrazine fuels for bimetallic catalytic microfluidic pumping.
The problem of controlling fluid flow on the microand nanolength scales is important in microanalysis, nanoparticle assembly, and other emerging applications. We and others have demonstrated autonomous nanoparticle movement and micrometer-scale fluid flow driven by the asymmetric catalytic decomposition of hydrogen peroxide over bimetallic surfaces.1-7 Movement on larger length scales has also ...
متن کاملHydrazine decomposition over Irn/Al2O3 model catalysts prepared by size-selected cluster deposition.
Hydrazine decomposition chemistry was probed over a temperature range from 100 to 800 K for a series of model catalysts prepared by mass-selected Ir(n)(+) deposition on planar Al(2)O(3)/NiAl(110). Two sets of experiments are reported. Temperature-programmed desorption (TPD) was used to study hydrazine desorption and decomposition on Al(2)O(3)/NiAl(110) and on a model catalyst prepared by deposi...
متن کاملCO oxidation catalysed by Pd-based bimetallic nanoalloys.
Density functional theory based global geometry optimization has been used to demonstrate the crucial influence of the geometry of the catalytic cluster on the energy barriers for the CO oxidation reaction over Pd-based bimetallic nanoalloys. We show that dramatic geometry change between the reaction intermediates can lead to very high energy barriers and thus be prohibitive for the whole proce...
متن کاملSize-controllable Ni5TiO7 nanowires as promising catalysts for CO oxidation
Ni5TiO7 nanowires with controllable sizes are synthesized using PEO method combined with impregnation and annealing at 1050(o)C in air, with adjustment of different concentrations of impregnating solution to control the dimension of nanowires. The resulting nanowires are characterized in details using X-ray diffraction, scanning electron microscopy, transmission electron microscopy and energy d...
