摘要: 黄豆杆作为一种可再生的生物质资源,成本低廉、环境友好,极具高值利用开发潜力. 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(X/℃, 表示碳化温度),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,从而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80 ℃反应0.75 h,硝基苯转化率为100 %,苯胺选择性为>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. 实现了农业废弃物黄豆杆的资源化利用,为开发高效、低成本、环境友好的生物质衍生碳基催化剂提供了新思路.

Abstract: 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-carbonization, hydrothermal processing, activation, and carbonization, soybean stalks were converted into nitrogen-doped carbon materials SSC-X (X/℃, denoting the carbonization temperature). By controlling preparation conditions, we modulated the porous structure, specific surface area, defect sites, and nitrogen species configuration of SSC-X to optimize its catalytic performance in nitrobenzene hydrogenation. The SSC-800 catalyst exhibited 100 % nitrobenzene conversion and >99 % aniline selectivity within 0.75 h at 80 °C in cyclohexane solvent using hydrazine hydrate as reducing agent. Remarkably, the catalyst maintained excellent recyclability with over 99 % aniline yield after 8 cycles. This work achieves sustainable utilization of agricultural waste soybean stalks and provides a novel strategy for developing efficient, low-cost, and environmentally friendly biomass-derived carbon-based catalysts.
