The invention discloses an antibacterial molecular sieve for an automobile fresh air system and a preparation method and application thereof, and belongs to the technical field of antibacterial molecular sieves, an AFI type framework is of a hexagonal prism structure with the length of 5 micrometers and 100 micrometers, the BET is 1010 m < 2 >/g, the micropore volume of the pore diameter of 0.91 nm is 0.55 cm < 3 >/g, the molecular sieve can be applied to removal of harmful substances, and the antibacterial molecular sieve can be used for removing harmful substances. The pore structure of the molecular sieve can adsorb microorganisms to the surface or inside, and the synergistic superposition antibacterial efficiency of the two effects is higher. Metal is utilized in a material structure instead of surface adsorption, the needed amount is reduced, loss is not prone to happening, cost is reduced due to reduction of the using amount, and the follow-up pollution problem is also reduced. And after heat treatment, no new crystal phase is generated, and no metal dissolution phenomenon exists. According to the present invention, the material has characteristics of simple preparation process, no heating and strong illumination in the use process, bacterial killing and oxycarbide purification effects, and can be processed into the required shape through pressing, sintering and pre-growth on the substrate to form the film, the 5 min sterilization effect is 99.7%, and the CO-to-CO2 conversion rate is 30%.

    本发明公开了一种用于汽车新风系统的抗菌分子筛及其制备方法和应用,属于抗菌分子筛技术领域,AFI型骨架,为5μm长度100μm的六棱柱结构,BET为1010m2/g,孔径0.91nm微孔体积为0.55cm3/g,分子筛本身可应用于有害物质的去除,分子筛的孔结构可以将微生物吸附到表面或内部,两种效应的协同叠加抗菌的效率更高。对金属的利用是在材料结构中而不是表面的吸附,所需的量降低而且不易损失,而用量的减少不仅使成本降低,也减小后续的污染问题。经过热处理也不会产生新的晶相,没有金属溶出的现象。使用过程中不需要加热和强光照,兼具杀灭细菌和净化碳氧化物的作用,材料可以通过压制、烧结以及预先生长在基底成膜的方式加工成所需形状,5min杀菌效果99.7%,CO到CO2转化率30%。
