In situ fabrication and electrochemical behavior of amino acid polyoxometalate nanoparticles-embedded microcapsules.
Amino acid polyoxometalate nanoparticles-embedded microcapsules were in situ fabricated by layer-by-layer (LbL) self-assembly method [polyoxometalate, H3PMo12O40·nH2O (PMo12); amino acid, glycine (Gly)]. The morphology of the obtained microcapsules was characterized by transmission electron microscopy and scanning electron microscopy. The electrochemical behavior of the amino acid polyoxometalate nanoparticles-embedded microcapsules was studied by cyclic voltammetry. The microcapsules show the pH-dependent properties, indicating that the pH of solution plays an important role in the electrochemical behavior of heteropolyanions.
