Activation Energy of the Belousov–Zhabotinsky Reaction in a Gel with [Fe(bpy)<sub>3</sub>] Catalyst
Access this Article
We synthesized a novel poly(ACMO-<i>co</i>-[Fe(bpy)<sub>3</sub>]) gel covalently bonded to an Fe-catalyst moiety for the Belousov–Zhabotinsky (BZ) reaction. The novel gel was composed of acryloyl morpholine (ACMO) and bis(2,2′-bipyridine)(4-vinyl-4′-methyl-2,2′-bipyridine)iron bis(hexafluorophosphate) ([Fe(bpy)<sub>3</sub>]·2PF<sub>6</sub>). The period of the BZ reaction in the poly(ACMO-<i>co</i>-[Fe(bpy)<sub>3</sub>]) gel decreased with increasing temperature. The activation energy of the self-oscillation of the gel was found to be 78 kJ mol<sup>−1</sup>, which is higher than that of the self-oscillating polymer system with [Ru(bpy)<sub>3</sub>] (about 60 kJ mol<sup>−1</sup>).
