The invention belongs to the technical field of harm and tar reduction of cigarettes, and particularly relates to an adsorbent material for reducing hydrocyanic acid release quantity in main stream smoke of cigarettes selectively as well as a preparation method thereof, wherein a porous material acts as a carrier of the adsorbent material; poly phthalocyanine metallic compounds are loaded on the surface of the carrier by the processes of impregnating, drying, roasting and the like sequentially, so that the adsorbent material develops a function of a catalyst in the smoke selectivity adsorption process, and the hydrocyanic acid release quantity in main stream smoke of cigarettes is reduced substantially. According to the invention, the using fields of poly phthalocyanine metallic compounds are widened; the types of adsorbent materials for reducing hydrocyanic acid in the tobacco harm reduction technical field increase; the provided preparation method of the adsorbent material is simple, is convenient to operate, is high in hydrocyanic acid preferential adsorption capability; moreover, raw materials are obtained easily, are low in cost, so that the adsorbent material for reducing hydrocyanic acid release quantity in main stream smoke of cigarettes selectively as well as the preparation method thereof have favorable popularization and application significance.
