摘要：

A simple hydrothermal method was applied to controllably synthesize porous FeVxOy one-dimensional (1-D) nanostructures. The length of the 1-D nanostructures could be tuned from several micrometers to several millimeters. The formation process of the porous FeVxOy 1-D nanostructures can be summarized in four steps, namely dissolution, anisotropic growth, Ostwald ripening and dehydration. It was found that the pore sizes decrease with increasing pH value while the surface areas also increase with increasing pH value. Finally, the porous FeVO4 nanorods were found to be very active and stable in the application of the selective catalytic reduction of NO with NH3.
