Honeycomb-patterned hybrid films of Surfactant-Encapsulated Polyoxometalate by breath figure method and its electrocatalysis for BrO3-

Abstract

In this paper, a sandwich type of Polyoxophosphotungstate K7Na3[Cu4(H2O)2(PW9O34)2]•20H2O (abbr. Cu4(PW9)2) was selected as an active united to construct inorganic/organic hybrid materials. The ordered honeycomb structures of surfactant-encapsulated polyoxometalate complex (SEP) was successfully obtained by a famous breath figures method. Cu4(PW9)2 maintain typical features as confirmed by IR spectra, magnetization hysteresis studies and UV-vis spectra. Investigation of the effects of the relative humidity on the morphology of the honeycomb structures, which demonstrated wide generality and high reproducibility of the formation of self-organized honeycomb-patterned films. In present experiment, this magnetic ordered honeycomb was successfully deposited on indium tin oxide (ITO) substrates by direct casting the SEP chloroform solution. The cyclic voltammertric responses showed the redox couples of Cu4(PW9)2. Electrochemical behavior of the electrode was studied. In addition, the modified electrode exhibited high electrocatalytic activity for reduction of BrO3-, which offered a new POM-based film material for the electrochemical areas.
