Abstract: The effect of pH value on preparation of nano-structured InVO4 by hydrothermal method was studied.Using InCl3,NH4VO3 as raw material to prepare nano-InVO4 by hydrothermal method under 150 ℃,adjusting the pH value of reaction system by NH3OH2O and hydrochloric acid,and characterizing the products by XRD and FTIR,the effect of pH on products’ generation was investigated when pH value of reaction system was 6.0,7.0,8.0,respectively.The results show that pH value influences generation of nano-InVO4.When it is 7.0,a higher purity orthorhombic nano-InVO4 can be prepared;when it is 6.0,the product obtained is a mixture of InVO4 and In(OH)3;when it is 8.0,the product obtained is In(OH)3.

Key words: nano-InVO4, hydrothermal method, effect of pH value
