摘要: High synthesis cost of mesoporous aluminosilicates (MA) limits their practical application. Recycling copolymer template employed in preparation MA is an effective way to reduce the cost. An ultrasonic extraction strategy for recycling organic P123 MAs reported. Effects different parameters on recovery are investigated and optimum conditions obtained. 75.0% recovered from within 10 min by one-step ultrasonication. Characterizations indicated that resulting P123-free (MA-U) exhibits excellent properties compared with calcined products. Moreover, can be synthesize high hydrothermally stable MA. This investigation provides a facile recycle
