摘要：

A novel resin immobilized iron(II) phenanthroline [FePR] is prepared, characterized and exploited to understand C-C/C-O cleavage in Rhodamine B dye under visible light (lambda >= 420 nm). Studies infer that both molecular oxygen and visible light are playing essential roles in photocatalysis, and pH is influencing the degradation. Photocatalysis by FePR involves oxo-iron ([Fe-IV(phen)(3) = O]) species as reactive intermediate. LC-MS studies on the aliquots of partially photodegraded RhB reveal benzoic acid as a main degradation product; however, complete degradation was achieved under optimum condition. Overall, the FePR is a stable heterogeneous photocatalyst, which can be used for advanced oxidative process in greener route. (C) 2014 Elsevier B.V. All rights reserved.
