Preparation method for hierarchically constructing magnesium oxide degerming functional material by using leaf template and application of magnesium oxide degerming functional material

The invention discloses a preparation method for hierarchically constructing a magnesium oxide degerming functional material by using a leaf template. The preparation method comprises the following steps: carrying out alkaline leaching on camphor tree leaves; dipping with pure water and carrying out acid leaching; dipping with pure water and absolute ethyl alcohol; and calcining and preserving heat of the sample to obtain the leaf template hierarchical structure magnesium oxide. The leaf template hierarchical structure magnesium oxide prepared by the invention has excellent degerming performance, the physical removal performance of bacteria is very efficient, reaches 99.4% and is 2.6 times that of leaf template activated carbon, and template-free MgO is 2.19 times that of the leaf template activated carbon; the antibacterial performance is 79.6%. 本发明公开了一种用树叶模板分级构造氧化镁除菌功能材料的制备方法，包括对樟树叶碱浸；纯水浸渍、酸浸；纯水浸渍、无水乙醇浸渍；样品经过煅烧保温后得到树叶模板分级构造氧化镁。本发明制备得到的树叶模板分级构造氧化镁具备优良的除菌性能，其中细菌物理去除性能非常高效，达到了99.4％，为树叶模板活性炭的2.6倍，无模板MgO为树叶模板活性炭
