ZIF-8 modified compound bacteria synergistically regulated biochar adsorption material and preparation method thereof

The invention discloses a ZIF-8 modified compound bacteria synergistically regulated biochar adsorption material and a preparation method thereof. The method comprises the following steps: culturing compound bacteria, pretreating biomass, carbonizing modified biomass, preparing a ZIF-8 composite material, and drying the product to obtain the ZIF-8 at compound bacteria biochar (ZIF-8 at BC) material. According to the method, the adsorption material obtained by taking the bagasse as the main biomass is low in preparation cost, environmentally friendly, simple in synthesis step, high in nitrogen content, high in CO2 adsorption effect and good in stability, and large-scale commercial production can be achieved easily. 本发明公开了一种ZIF-8改性复合菌协同调控生物炭吸附材料及其制备方法。该方法包括复合菌的培养、生物质前处理、改性生物质的碳化、ZIF-8复合材料的制备，将上述产物烘干后得到ZIF-8@复合菌生物炭(ZIF-8@BC)材料。所述方法以甘蔗渣为主要生物质得到的吸附材料制备成本低廉，绿色环保，合成步骤简单且含氮量较高，对CO2吸附效果较强，且具有良好的稳定性，有利于实现大规模的商业化生产。
