- Abstract
A simple one-pot synthesis of RuO
2 nanoparticles by the thermal decomposition of ruthenium nitrosyl nitrate [Ru(NO)(NO
3)
3] up to 800 °C was investigated. The RuO
2 phase was characterized by XRD, SAXS, FE SEM/EDS, Raman, DTA/TGA and FT-IR techniques. Broadening of prominent diffraction lines (110), (101) and (211) was used to estimate nanocrystallite sizes in RuO
2 particles. FE SEM showed the formation of RuO
2 plates at 400 °C which consisted of RuO
2 nanoparticles of about 15-25 nm in size. At 800 °C RuO
2 nanoparticles showed the sintering effect and some of them increased in size to about 200 nm. Raman and FT-IR spectra consolidated the findings. Moreover, DTA curves showed the decomposition and release of NO and NO
