The invention relates to a hybrid graphene material and a filter able to totally or partially retain polyaromatic hydrocarbons, carbonyl and other compounds from smoke from tobacco products or industrial processes, which has activated carbon and graphene materials as adsorbent substances, both supported by the same matrix and in the same compartment of the filter, which is optionally connected to another compartment of a conventional filter comprising fibres of cellulose acetate or a similar polymer. The invention also relates to a method for producing the material. 本发明涉及杂合石墨烯材料和能够完全或部分地保留来自烟草产品或工业过程的烟雾中的多环芳烃、羰基化合物和另一些化合物的过滤器，所述过滤器具有活性炭和石墨烯材料作为吸附剂物质，活性炭和石墨烯材料两者由同一基体负载并且在同一过滤器隔室中，所述过滤器隔室任选地连接至另一个包含乙酸纤维素纤维或类似聚合物的常规过滤器隔室。本发明还涉及用于制备所述材料的方法。
