This article has been retracted at the request of the Editor-in-Chief. Please see http://www.elsevier.com/locate/withdrawalpolicy.Reason: There are only minor differences between the papers submitted to Applied Catalysis A: General [308 (2006) 91–98] and to Catalysis Communications [8 (2007) 619–624]. The authors did not answer the reproach of self-plagiarism, therefore the paper in Catalysis Communications is withdrawn by the editor.
