Abstract: |
The composition of non-nobile metal catalyst for catalytic wet oxidation is formed from active component CeO2 (60-90%), TiO2 (5-36%) and electronic adjuvant Bi2O3 (4-15%). Its preparation method includes the following steps: firstly, dissolving raw materials in water or nitric acid, dropping ammonia water in the obove-mentioned liquid mixture, and controlling pH value, heating and stirring, standing still and precipitating, centrifugal cleaning, drying and roasting so as to obtain the invented product. Said invented product possesses excellent stability, and its cost is greatly reduced. |
