    Bismuth Phosphotungstate to Prepare Metathesis Method

    1. Weigh 11.5g (4mmol) phosphotungstic acid (HPW) and dissolve in 10mL of water to completely dissolve with constant stirring;
    2. Add 1.3g (4mol) bismuth trichloride (BiCl3) to the above solution and stir for 2h to carry out a metathesis reaction, the reaction formula as follows:
    H3PW12O40+BiCl3→BiPW12O40+3HCl
    3. Place the resulting solution in oven for drying for 4 hours at 110℃ to give an off-white solid;
    4. Generate the green solid powder of bismuth phosphotungstate after calcining at 400℃ for 3 hours.
