Synthesis and characterization of nanocrystalline RuO2 powders
The synthesis of nanocrystalline RuO2 powders by combining “ wet” chemical precipitation, autoclaving and thermal treatment of amorphous precursors has been investigated. Amorphous RuO2 precursors were precipitated from RuNO(NO3)3 or RuCl3 solutions by adding NH4OH solution up to ~pH 5. The samples were characterized by DTA, XRD, FT- IR spectroscopy and TEM. The control of particle size was achieved by heating of amorphous precursor due to regular particle (crystallite) growth. Nanosized RuO2 particles were formed up to 450°C. However, at 600°C the size of RuO2 particles was significantly increased.
