The invention belongs to the technical field of cigarette harm reduction, in particular to a ZIF-Zn @ porous starch composite material, a preparation method and the application thereof in cigarette. The invention activates porous starch, further grinds into fine powder, takes methanol as solvent, reacts organic ligand Huawei, metal zinc salt and activated porous starch at constant temperature fora certain time, and separates the product, namely ZIF-A Zn @ porous starch composite material is added into the cigarette filter rod to form a binary composite filter rod when the filter rod is molded. As that composite filter rod provided by the present application is adopt, Not only can the tar in the mainstream smoke be reduced, but also the harmful hydrocyanic acid in the cigarette smoke can be selectively reduced by 30.7%, so as to achieve the purpose of selectively reducing the HCN release amount in the mainstream smoke. When the adsorbent is applied to the binary compound nozzle, it shows a good application pro
