摘要
Stabilization and solubilization of electrogenerated [Co(I)(phen)(3)](1+) and its mediated electrocatalytic reduction on perchloroethylene is primary investigation. High concentrated surfactant (>48 mM) cetyltrimethylammonium bromide (CTAB) is utilized as micellar solution to establish the both stabilization and solubilization of electrogenerated Co(I). Initial cyclic voltammetry studies demonstrates that the electro-generated Co(I) is stabilized effectively in CTAB micellar solution from its decomposition. Also, the solubilization of PCE in CTAB micellar solution reflects clearly by mediated catalytic reduction through micellar stabilized electrogenerated Co(I) aqueous solution. PCE reduction started at same potential of Co(I) and at the cost of Co(I) clearly indicates the formation of [Co(I)(phen)(3)](1+) and not labile complex [Co(II)(phen)(2)](1+). The homogeneous rate constant (k(homo)) between micellar solubilized [Co(I)(phen)(3)](1+) and PCE is determined by using cyclic voltammetry studies and it found to be 8.9038 M(-1)s(-1). Product analysis by GC confirms the PCE reduction in micellar composite solution. The CTAB micellar solution is promising to get active catalyst [Co(I)(phen)(3)](1+) and for PCE reduction in aqueous medium.
