摘　　要：通过使用无模板法,在温和的水溶液条件下,以K_8[α-Si W_(11)O_(39)]为原料合成了一种MSiW_(12)微米管(M=银纳米粒子,多壁碳纳米管),并对其电化学性质进行了进一步研究.有趣的是,目前纳米材料作为掺杂剂引入多金属氧酸盐微米管中的报道还很少.详尽的对照实验表明,掺杂剂浓度对微米管生长起着关键性作用.同时,对目标化合物循环伏安性质的研究证明其具有优良的电化学性质.因此,该研究为今后提高多金属氧酸盐微纳米材料的电化学性质开辟了新途径.Based on silicotungstate,the synthesis and electrochemical property of MSiW12microtubes(M=silver nanoparticles or multi-walled carbon nanotube)are demonstrated,which were prepared by template-free method under mild solution conditions.Interestingly,nanomaterials as dopants are rarely introduced into polyoxometalate microstructure.In this work,detail control experiments have been carried out,indicating the concentration of dopants play a key role in microtube growing.Meanwhile,cyclic voltammetry spectroscopy has been recorded to illustrate the electrochemical performance of title materials.Therefore,these results provide an enlightening way to enhance the electrochemical property of polyoxometalate materials.
