Embodiment 1
[0020] Utilize the method of the present invention, prepare the Ti of 500 ℃ annealing treatment 1-x V x o 2 (x=0.08) Nanopowder. First, weigh 0.01 mol of ammonium metavanadate and put it into a 100mL beaker, add 30mL of glacial acetic acid, dissolve it under ultrasonic dispersion, wash the beaker continuously with absolute ethanol, transfer the solution into a 100mL volumetric flask, add absolute ethanol to adjust When the concentration reaches 0.05mol / L, prepare a precursor solution of vanadium ions; in addition, dissolve tetrabutyl titanate in absolute ethanol, transfer the solution into a 100mL volumetric flask, and prepare a precursor solution of 0.5M titanium ions. In the second step, use a 10mL graduated pipette to take 40mL of the solution containing titanium ions and place it in a 100mL beaker, then use a 2mL graduated pipette to take 3.5mL of the solution containing vanadium ions, and quickly drop it into the above solution while stirring continuously. The molar ra...
