Abstract

Designing efficient catalysts for the preferential hydrogenation of vinyl groups is a pivotal challenge in the production of pharmaceuticals, agrochemicals, fine chemicals, dyes, and other valuable compounds. Herein, we developed evenly dispersed bimetallic Pd–Co nanoparticles on mesoporous silica nanospheres (MSNs) for selective hydrogenation of a model compound 3-nitrostyrene. By tuning the Pd/Co molar ratio and solvents, the efficiency of 3-nitrostyrene hydrogenation to 3-ethylnitrobenzene with the Pd1–Co1/MSN-Nb catalyst was well optimized; while 3-nitrostyrene was converted entirely, the selectivity of 3-ethylnitrobenzene was up to 95%. Moreover, this catalyst was stable and compatible with styrene and its derivatives. Further characterization results indicated that the combined effect of Pd-based metal nanoparticles and MSN-Nb and the electronic interaction between Pd and Co components in the Pd1–Co1/MSN-Nb catalyst have significant importance in the hydrogenation of 3-nitrostyrene. The aforementioned catalytic system will prove invaluable in guiding the selective hydrogenation of vinyl groups.

介孔二氧化铌固定化Pd-Co双金属纳米颗粒选择性加氢3-硝基苯乙烯
设计高效的乙烯基优先加氢催化剂是制药、农用化学品、精细化学品、染料和其他有价值化合物生产中的关键挑战。在此,我们在介孔二氧化硅纳米球(MSNs)上制备了均匀分散的双金属Pd-Co纳米颗粒,用于模型化合物3-硝基苯乙烯的选择性加氢。通过调整Pd/Co的摩尔比和溶剂,优化了Pd1-Co1 /MSN-Nb催化剂催化3-硝基苯乙烯加氢制3-乙基硝基苯的效率;当3-硝基苯乙烯完全转化时,3-乙基硝基苯的选择性可达95%。该催化剂与苯乙烯及其衍生物具有良好的相容性和稳定性。进一步的表征结果表明,Pd基金属纳米颗粒与MSN-Nb的联合作用以及Pd- co1 /MSN-Nb催化剂中Pd和Co组分之间的电子相互作用对3-硝基苯乙烯的加氢反应具有重要意义。上述催化体系将证明在指导乙烯基选择性加氢方面是无价的。
