Synthesis of Nb 2 O 5 Nanorods by a Soft Chemical Process

Single crystalline Nb 2 O 5 nanorods have been successfully synthesized by a soft chemical process, in which only metal Nb powder and water were used as the starting materials. The synthesized Nb 2 O 5 nanorods are highly crystalline and their growth is along [001] direction. The diameter of the nanorods is found to be ca. 50 nm and their lengths up to several micrometers. Based on the experimental results of XRD, SEM, and TEM measurements, the possible mechanism for the formation of Nb 2 O 5 nanorods was discussed

Non-promoted Ru/sepiolite catalyst for ammonia synthesis

154-158Sepiolite was used as support for ruthenium catalyst. Non-promoted Ru/Sep is proved to be effective for ammonia synthesis. The catalyst was characterized by XRD, XPS and nitrogen adsorption isotherms. Ru is reduced completely and is present in few oxidation states on the support. Using non-aqueous solvent instead of water in the impregnation process on basic support, the Ru dispersion could be increased. Chlorine-free Ruthenium catalyst was prepared using RuCl3 by washing with ammonia solution
