A high-performance bifunctional catalyst with a 2D [TeMo6O24]-based framework for efficient CEES oxidation and electrochemical sensing of Cu2+
Under hydrothermal conditions, a two-dimensional (2D) Anderson-type polyoxometalate-based framework {[Cu(dap)2][Cu(dap)(H2O)2]2[TeMo6O24]} (1, dap = 1,2-diaminopropane) was synthesized and characterized by single crystal X-ray diffraction analysis, elemental analysis, IR spectroscopy, electrochemical impedance spectroscopy and powder X-ray diffraction. Complex 1 features an unusual mixed-linkage 2D metal–organic network constructed from both single [Cu(dap)2]2+ and double [Cu(dap)(H2O)2]2+ linkers. As a heterogeneous catalyst, 1 exhibited outstanding catalytic performance for the oxidation of 2-chloroethyl ethyl sulfide, achieving 99.1% conversion and 100% selectivity toward CEESO within 10 min at 35 °C, accompanied by excellent structural and catalytic stability. Moreover, 1 demonstrated promising electrochemical sensing properties of Cu2+ ions, showing a low limit of detection of 0.492 μM, a high sensitivity of 0.426 μA μM−1 and good anti-interference ability.
期刊介绍：
Transition Metal Chemistry is an international journal designed to deal with all aspects of the subject embodied in the title: the preparation of transition metal-based molecular compounds of all kinds (including complexes of the Group 12 elements), their structural, physical, kinetic, catalytic and biological properties, their use in chemical synthesis as well as their application in the widest context, their role in naturally occurring systems etc.
Manuscripts submitted to the journal should be of broad appeal to the readership and for this reason, papers which are confined to more specialised studies such as the measurement of solution phase equilibria or thermal decomposition studies, or papers which include extensive material on f-block elements, or papers dealing with non-molecular materials, will not normally be considered for publication. Work describing new ligands or coordination geometries must provide sufficient evidence for the confident assignment of structural formulae; this will usually take the form of one or more X-ray crystal structures.
