Supported transition metal oxides and vanadium-containing multi-metallic oxides were investigated to develop new catalysts for the catalytic destruction of highly toxic polychlorinated aromatic pollutants such as polychlorinated benzenes, polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs), and/or biphenyls (PCBs) from waste gases. The decomposition of 1,2-dichlorobenzene (Cl2Bz) w...

Realization of a robust nanotube-heterostructure tunneling transistors [Solid State Comm. 116, 569 (2000)] requires the difficult formation [Science 293, 76 (2001)] of a central nanoscale barrier separating a pair of outside metallic leads. Here I suggest an alternative surface-based assembly based on self-organization of one-dimensional metallic states on oxides and trapping well-resolved reso...

One of the most exciting prospects of nanotechnology is the possibility to exploit the relation between chemical reactivity and system size. Small particles are known to enhance the reactivity of molecules with metals and/or oxides. Metallic nanowires, and, in particular, atomic chains as those formed in stretched Au nanocontacts, are expected to offer the ultimate limit for the increase in rea...

The effect of gold presence on carbon monoxide oxidation and ethanol steam reforming catalytic behavior of two Ce-Zr-Co mixed oxides catalysts with a constant Co charge and different Ce/Zr ratios was investigated. The Ce-Zr-Co mixed oxides were obtained by the pseudo sol-gel like method, based on metallic propionates polymerization and thermal decomposition, whereas the gold-supported Ce-Zr-Co ...
