Tobacco stalk, a kind of agricultural residue, will cause environmental pollution because it contains some harmful substances such as nicotine. To realize the high-value utilization of this agricultural residue, we prepared porous carbon (TS-C) by high temperature carbonization using tobacco stalk as a precursor. It was found that TS-C displays a hierarchical pore structure and high Brunauer-Emmett-Teller (BET) surface area of 1416 m g. Moreover, TS-C has excellent performance in organic dye adsorption at room temperature, especially for Gentian violet (GV), with the maximum adsorption capacity of 926 mg g.
烟草秸秆是一种农业废弃物，因其含有尼古丁等有害物质会造成环境污染。为实现这种农业废弃物的高值化利用，我们以烟草秸秆为前驱体通过高温碳化制备了多孔碳（TS-C）。研究发现，TS-C呈现出分级孔结构，其布鲁诺尔-埃米特-泰勒（BET）比表面积高达1416 m²/g。此外，TS-C在室温下对有机染料具有优异的吸附性能，尤其是对结晶紫（GV），其最大吸附容量为926 mg/g。
