Synthesis and Electrochemical Behavior of Two Microporous Polyoxomolybdates
Two new microporous polyoxomolybdates of (NH4)2γ-Mo8O26 (Compound I) and (NH4)2Mo4O13 (Compound II) were synthesized hydrothermally and characterized by elemental analysis, infra-red, TG analysis and single-crystal X-ray diffraction. In the synthesis process, we found that both organic template and transition metal salt play crucial roles in the formation of crystals. Cyclic voltammetry was used to study their electrochemical properties. The results reveal that the two compounds possess electrochemical activity in 0.2M H2SO4+Na2SO4 ( pH=1 ) solution and three multi-electron transferred redox reaction (I-I′, II-II′ and III-III′) processes were obtained. The first two redox reactions (I-I′, II-II′) are reversible reaction processes but another one (III-III′) is not. The electrochemical properties of the two compounds indicate their great potential applications in electroanalysis and electrocatalysis.
