摘要
黄豆杆作为一种可再生的生物质资源,其成本低廉、环境友好,具有高值利用的开发潜力.将黄豆杆经预碳化、水热、活化和碳化等处理转化为氮掺杂碳材料SSC-X,通过控制制备条件调变SSC-X的孔隙结构、比表面积、缺陷位量及氮物种的构型,优化其催化硝基苯加氢反应的性能.催化剂SSC-800在水合肼作还原剂的环己烷溶剂中于80℃反应0.75 h,硝基苯转化率为100%,苯胺选择性为大于99%,循环使用8次后仍具有良好的催化活性,苯胺的收率保持在99%以上.
Soybean stalk,as a renewable biomass resource with low cost and environmental friendliness,demonstrates significant potential for high-value utilization.Through sequential treatments including pre-carboniza⁃tion,hydrothermal processing,activation,and carbonization,soybean stalks were converted into nitrogen-doped carbon materials SSC-X.By controlling preparation conditions,the porous structure,specific surface area,defect sites,and nitrogen species configuration of SSC-X were modulated to optimize its catalytic performance in nitrobenzene hydrogenation.The SSC-800 catalyst exhibits nitrobenzene conversion of 100%and aniline selectivity of>99%within 0.75 h at 80℃in cyclohexane solvent using hydrazine hydrate as reducing agent.Remarkably,the catalyst maintains excellent recyclability with aniline yield over 99%after 8 cycles.This work achieves sustainable utilization of agricultural waste of soybean stalks and provides a novel strategy for developing efficient,low-cost,and environmentally friendly biomass-derived carbon-based catalysts.
