Embodiment 1
[0044] Step 1: Add 2.4g of sodium metavanadate and 3.6g of thioacetamide into 60ml of deionized water at the same time, and magnetically stir for 60min at a speed of 600r / min to obtain a semi-clear solution A;
[0045] Step 2: Then add 0.7mol / L ammonia solution dropwise to solution A, control the drip rate of ammonia solution to 0.15ml / min, after adding one drop of ammonia solution, stir until the pH value of the solution is stable, then drop in Add a drop of ammonia solution until the pH value of the solution reaches 10.6 to obtain solution B;
[0046] Step 3: Pour solution B into the reaction liner according to the filling ratio of 60% and seal it, install the liner in the outer kettle and fix it, place it in a homogeneous reactor, and heat it from room temperature to 180℃ hydrothermal reaction for 24h;
[0047] Step 4: After the hydrothermal reaction is completed, the reaction kettle is naturally cooled to room temperature, and then the product cooled after the reaction is...
