Abstract

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.

摘要

氨基酸多金属氧酸盐纳米粒子嵌入微胶囊是通过层层自组装方法原位制备的[多金属氧酸盐，H3PMo12O40·nH2O (PMo12); 氨基酸，甘氨酸（Gly）]。通过透射电子显微镜和扫描电子显微镜对所得微胶囊的形态进行了表征。通过循环伏安法研究了氨基酸多金属氧酸盐纳米粒子嵌入微胶囊的电化学行为。微胶囊表现出 pH 依赖性，表明溶液的 pH 值对杂多阴离子的电化学行为起着重要作用。
