| 摘 要： | 在合成(NH4)3PMo12O40和K3PMo12O40的基础上,用改进的方法合成了(NH4)3AsMo12O40和K3AsMo12O40,以FTIR、XRD、TG-DTA、ESR和TPR等手段对其结构、热稳定性和还原性进行了考查,当中心原子由P换成As后,杂多钼酸盐热稳定性下降,还原性提高.

| Abstract: | Four heteropolymolybdates with (XMo12O40)3 anion of different center atom(X = P, As) have been synthesized, among them (NH4)3AsMo12O40 and K3AsMo12O40 synthesized by improved method. The structure, thermal stability and reducibility of each compound were examined by means of FTIR, XRD, TG-DTA, ESR, TPR, and so on. It is found that thermal stability decreases and reducibility increases when the center atom P changes into As. |
