摘要: We report for the first time that carbonyl meso-tetrakis(4-N-methylpyridiniumyl)porphyrinatoruthenium(II) tetraacetate (Ru-TPyP) worked as a catalyst Belousov–Zhabotinsky (BZ) reaction. The profiles from BZ reaction were measured by potentiometric measurements with Pt electrode and Hg/HgNO3 reference electrode. Ru-TPyP was added lastly to aqueous solution containing malonic acid (MA), sodium bromate (NaBrO3), nitric (HNO3) at 22 ± 2 °C. oscillation of observed over fixed period only in 2.1 × 10−2 M MA, 3.2 NaBrO3 5.5 HNO3. self-oscillation approximately 100 s it continued 2600 s.
