A new method for constructing three-dimensional models of bimetallic nanoparticles is proposed. This method, which is based on X-ray absorption spectroscopy data on the number and type of nearest neighbors, provides information on the distribution of types of atoms over the nanoparticle volume. The application of the method to the study of the structures of platinum–copper and platinum–silver nanoparticles of metal–carbon electrocatalysts has allowed to distinguish the nanoparticles with a core–shell structure from the nanoparticles with structure of disordered alloy or clusterized solid solution. 相似文献

The transport coefficients and thermoelectric figure of merit ZT for bulk nanostructured materials based on Bi2Te3-Sb2Te3 solid solutions have been investigated theoretically. Similar materials prepared by rapid quenching of the melt with the subsequent grinding and sintering contain amorphous and nanocrystalline regions with different sizes of particles. According to the performed estimations, the thermoelectric figure of merit of the amorphous phase can exceed the value of ZT for the initial solid solution by a factor of 2?C3 primarily due to the significant decrease in the thermal conductivity. The effective transport coefficients of the medium as a whole have also been investigated as a function of the parameters of each phase, and the concentration range of the amorphous phase, which corresponds to the effective values ZT > 1, has been determined. 相似文献
