Abstract:Four chain-like hybrid compounds based on mixed carboxylic acid ligands-modified polyoxomolybdates, K2H[(H2O)(4)M] [AsMo6O21(Ala) (PHBA)(2)]center dot nH(2)O 1-4 (M = Co, Ni, Zn, Mn; Ala = alanine; PHBA = p-hydroxybenzonic acid), were prepared and characterized by elemental analysis, IR spectroscopy, solid diffuse reflective spectroscopy, TG analysis, powder X-ray diffraction, and single-crystal X-ray diffraction. Four isostructural compounds 1-4 not only represent the extended architectures constructed from two different organic ligands-modified polyoxometalates but also can rapidly catalyze the degradation of two chemical warfare agent simulants, 2-chloroethyl ethyl sulfide (GEES) and diethyl cyanophosphonate (DECP), at room temperature. The catalytic results were analyzed and confirmed by GC-FID, GC-MS, and (HNMR)-H-1 techniques. Within 5 min, CEES was high-selectively oxidized to the corresponding nontoxic 2-chloroethyl ethyl sulfoxide (CEESO) using heterogeneous catalyst 1 with the oxidant H2O2 (conversion % = 98.5%, selectivity % > 99.9%). FTIR, PXRD techniques, and the following cycles also ascertained the stability and structural integrity of 1 in the oxidation reaction. Within 10 min, DECP can be almost entirely hydrolyzed to the nontoxic products catalyzed by 1 (conversion % = 99.0%). To our knowledge, they are in the rank of highly active catalysts for the degradation of CEES and DECP to date, accompanied by the advantages of steady reuse.
In 2002, Prof. Haiyan An received the B.S. degree in chemistry Northeast Normal University, Changchun, China; the M.S. in 2004 and the Ph.D. degree in 2007 in Key Laboratory of Polyoxometalates (POMs) Science of Ministry of Education. There were 30 papers published in Angew. Chem. Int. Ed., Inorg. Chem., Cryst. Growth Des., etc. during the degree. In 2006, she was awarded the Excellent Doctoral Dissertations Fund of Northeast Normal University. In July 2007, Prof. An joined College of Chemistry, Dalian University of Technology in the field of POMs. Her research interests are mainly focuse on the design, synthesis and properties’research of POM-based functional complexes with catalytic and drug activity. She has Undertaked two National Natural Science Foundation of China, one Specialized Research Fund for the Doctoral Program of Higher Education, one Natural Science foundation of Liaoning Province and one Scientific Research Foundation for Doctor of Liaoning Province. There are more than 30 SCI papers have been officially published in foreign periodicals during the work period, more than 20 of which list her as the first author and corresponding author.
