• Remarkably high catalytic activity of the RuIII(edta)/H2O2 system towards degradation of the azo-dye Orange II
  作者：Debabrata Chatterjee、Erika Ember、Ujjwal Pal、Sarita Ghosh、Rudi van Eldik

  DOI：10.1039/c1dt10483g

  日期：——

  The RuIII(edta)/H2O2 system (edta4− = ethylenediaminetretaacetate) was found to degrade the azo-dye Orange II at remarkably high efficiency under ambient conditions. Catalytic degradation of the dye was studied by using rapid-scan spectrophotometry as a function of [H2O2], [Orange II] and pH. Spectral analyses and kinetic data point towards a catalytic pathway involving the rapid formation of [RuIII(edta)(OOH)]2− followed by the immediate subsequent degradation of Orange II prior to the conversion of [RuIII(edta)(OOH)]2− to [RuIV(edta)(OH)]− and [RuV(edta)(O)]−via homolysis and heterolysis of the O–O bond, respectively. The higher oxidation state Ru(IV) and Ru(V) complexes react three orders of magnitude slower with Orange II than the Ru(III)-hydroperoxo complex. In comparison to biological oxygen transfer reactions, the Ru(edta) complexes show the reactivity order Compound 0 ≫ Compounds I and II.

  在环境条件下，发现RuIII(edta)/H2O2体系（edta4− = 乙二胺四乙酸）以极高的效率降解偶氮染料橙II。通过使用快速扫描分光光度法，研究了催化降解染料随[H2O2]、[橙II]和pH值的变化。光谱分析和动力学数据指向一个催化途径，其中涉及[RuIII(edta)(OOH)]2−的快速形成，随后紧接着在[RuIII(edta)(OOH)]2−转换为[RuIV(edta)(OH)]−和[RuV(edta)(O)]−之前对橙II进行降解，这两个转换分别通过O–O键的均裂和异裂进行。高氧化态的Ru(IV)和Ru(V)复合物与橙II的反应速度比Ru(III)-过氧化氢复合物慢三个数量级。与生物氧传递反应相比，Ru(edta)复合物的反应活性顺序为化合物0 ≫ 化合物I和化合物II。
