A new type of cigarette butts/coal‐based composite porous carbon was prepared by potassium hydroxide chemical activation method and used for methane decomposition to hydrogen. The effects of mass mixing ratio of the used cigarette butts/coal and carbonization temperature on the surface properties and structure of carbon materials were studied. The results show that the optimal mass mixing ratio of cigarette butts/coal is 1:3, and the increase in temperature can promote the specific surface area of carbon materials from 1850 to 2785 m²/g, the distribution of pore size is also changed from a large number of micropores to mesopores, and the structure became more disordered. DT/YT‐3‐1023 has the highest initial activity, DT/YT‐3‐1123 has the highest stability, and a certain amount of carbon fibers are deposited on the surface of carbon materials after the reaction.

烟头/煤基多孔碳的制备及其甲烷分解为氢的催化作用

通过氢氧化钾化学活化法制备了一种新型的烟头/煤基复合多孔碳，并将其用于甲烷分解为氢。研究了用过的烟头/煤的质量混合比和碳化温度对碳材料表面性能和结构的影响。结果表明，烟头/煤的最佳混合比为1：3，温度的升高可将碳材料的比表面积从1850提高到2785 m ^2。/ g，孔径的分布也从大量的微孔变为中孔，并且结构变得更加无序。DT / YT-3-1023的初始活性最高，DT / YT-3-1123的稳定性最高，反应后一定数量的碳纤维沉积在碳材料的表面。
