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. 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.
