通过低热固相反应合成了纳米(NH4)3PMo12O40·4H2O,XRD、31PNMR研究发现,在此固相反应的4个步骤中(扩散,反应,成核,生长),反应的速率控制步骤是产物的成核.
The nano-sized (NH4) 3PMo12O40¡¤4H2O was synthesized by low-temperature solid-state reaction. The XRD and 31PNMR results showed that in the four steps of solid phase reaction (diffusion, reaction, nucleation and growth), the rate control step of the reaction was Nucleation.
