AlOOH-loaded mullite porous ceramic as well as preparation method and application thereof
The invention relates to an AlOOH-loaded mullite porous ceramic as well as a preparation method and application thereof, belongs to the technical field of ceramics, and solves the problems that an existing adsorbent is high in cost and limited in adsorption effect. The preparation method comprises the following steps: step 1, preparing gel; step 2, injecting the gel obtained in the step 1 into a mullite fiber felt, soaking the mullite fiber felt into the sol to enable the sol to be gelated in the mullite fiber felt, and then obtaining the mullite porous ceramic through drying and sintering processes; step 3, preparing an acidic Al solution; and 4, mixing the mullite porous ceramic obtained in the step 2 with the acidic Al solution obtained in the step 3, carrying out hydrothermal synthesis, carrying out ultrasonic cleaning, and drying to obtain the AlOOH-loaded mullite porous ceramic. The AlOOH-loaded mullite porous ceramic disclosed by the invention is relatively high in compressive strength and has filtration and adsorption properties.
本发明涉及一种负载AlOOH的莫来石多孔陶瓷及其制备方法和应用，属于陶瓷技术领域，解决了现有的吸附剂成本高，吸附效果有限的问题。制备方法包括：步骤1：制备凝胶剂；步骤2：将步骤1中所得凝胶剂注入莫来石纤维毡中，将莫来石纤维毡浸泡于溶胶中，使得溶胶在莫来石纤维毡中凝胶，然后通过干燥和烧结工艺得到莫来石多孔陶瓷；步骤3：制备酸性Al溶液；步骤4：将步骤2所得莫来石多孔陶瓷与步骤3所得酸性Al溶液混合，进行水热合成、超声清洗、干燥得到负载AlOOH的莫来石多孔陶瓷。本发明的负载AlOOH的莫来石多孔陶瓷抗压强度较高，并且兼具过滤和吸附性能。
