| titleOfInvention | A low-cost method for preparing nano-titanium-silicon molecular sieves |
| abstract | The invention provides a low-cost method for preparing nano-titanium-silicon molecular sieves, which is characterized in that silicon sources, titanium sources and seed crystals are uniformly mixed, and inorganic acid is added to adjust the pH value of the mixed solution to a range of 1 to 6. Aging for a certain period of time, then filtering, washing, and drying to obtain a molecular sieve crystallization precursor; mixing the titanium-silicon mixed precursor with an alkaline aqueous solution containing a templating agent, placing it in a closed container, and crystallizing at 120-210°C for 0.5-3d, Separation by filtration, drying and roasting to obtain titanium silicon molecular sieves. The method for synthesizing the titanium-silicon molecular sieve provided by the invention has low requirements on the purity of raw materials, and at the same time, the aqueous solution of the molecular sieve template can be reused, thereby reducing the synthesis cost of the titanium-silicon molecular sieve and reducing waste water discharge. |
