Abstract Adsorption of stubborn sulfides from fuels is a feasible desulfurization strategy to obtain clean fuels, however, the exploration of efficient adsorbents to achieve this target remains a formidable challenge. Here, a hybrid nanocomposite comprising carbon-doped boron nitride (BN) and ZIF-8 derived carbon was constructed through a facile one-pot pyrolysis method. Thanks to the hierarchical porous structure and more exposed Lewis acid sites, the obtained adsorbent gave remarkable desulfurization performance for dibenzothiophene (DBT, 35.6 mg S/g), which was superior to that of the state-of-the-art carbon-doped BN reported under similar conditions so far. Moreover, the as-prepared absorbent exhibited impressive adsorptive capacity for 4-methyldibenzothiophene (4-MDBT) and 4,6-dimethyldibenzothiophene (4,6-DMDBT). Therefore, the BN-C hybrid materials presented here hold great promise for adsorptive desulfurization, as well as other related fields.

用于吸附脱硫的 BN/ZIF-8 衍生碳杂化材料:对吸附性能和反应动力学的洞察

摘要 吸附燃料中顽固的硫化物是获得清洁燃料的一种可行的脱硫策略,但探索高效吸附剂以实现这一目标仍然是一项艰巨的挑战。在这里,通过简便的一锅热解法构建了一种包含碳掺杂氮化硼 (BN) 和 ZIF-8 衍生碳的混合纳米复合材料。由于分层多孔结构和更多暴露的路易斯酸位点,所获得的吸附剂对二苯并噻吩(DBT,35.6 mg S/g)具有显着的脱硫性能,优于最先进的碳掺杂 BN迄今为止在类似条件下报告。此外,所制备的吸收剂对 4-甲基二苯并噻吩 (4-MDBT) 和 4,6-二甲基二苯并噻吩 (4,6-DMDBT) 表现出令人印象深刻的吸附能力。所以,
