1New insights for the catalytic oxidation of cyclohexane to K-A oil显示文摘Au-based catalysts have been reported to be active in the cyclohexane oxidation to K-A oil, but they showed some limitiations in terms of productivity, selectivity and required reaction conditions. The possibility to overcome some of these limits has been explored coupling Au with Cu, which can be suitable for undergoing the electron-switch in the initial step of the cyclohexane oxidation. Hence, a bimetallic 2 wt% Au Cu/Al_(2)O_(3) catalyst was tested in the oxidation of cyclohexane, working at mild conditions of 120 ℃ and 4 bar of O_(2). The combination of the catalyst with a very small amount of benzaldehyde used as cheaper and non-toxic radical initiator allowed to obtain a very high productivity of cyclohexanol and cyclohexanone(45 mmol*m L/mgmet*h) with a selectivity of 94%. Moreover, comparing the catalysed reaction with the non-catalysed one, the role of the catalyst has been disclosed.Alessandro Vomeri Marta Stucchi Alberto Villa Claudio Evangelisti rea Beck Laura Prati 2022Journal of Energy Chemistry2022,31,7:4

3Au-Ir催化剂用于生物质衍生物加氢(英文)显示文摘采用沉积-沉淀法制备了TiO_2负载的Au-Ir和Au-Ru催化剂,用于乙酰丙酸加氢制γ-戊内酯反应,并与相应的单金属催化剂性能进行了比较.有趣的是,Ir/TiO_2中添加Au抑制了催化剂活性,而添加Ru则表现出正效应的协同作用.这两个催化剂均在H_2中还原,使得M^0–Au^0间相互作用增强.结合以前的密度泛函理论计算和催化反应结果,我们认为,Au-Ir/TiO_2催化剂活性低于Ir/TiO_2催化剂是由于Au影响了Ir原子的氧化还原过程.Lorenzo Landenna Alberto Villa Rodolfo Zanella Claudio Evangelisti Laura Prati 2016Chinese Journal of Catalysis2016,37,10:1
4铜/二氧化硅催化剂中金属纳米粒子构性关系的一些认识(英文)显示文摘考察了化学吸附水解法制备的两种铜/二氧化硅催化剂上3-甲基环己酮加氢反应活性.发现两种催化剂在60℃和1bar H2下催化活性非常高.吸附CO红外光谱和透电镜结果表明,催化剂中存在结晶良好的铜颗粒.通过假设一个立方八面体模型,我们可以证明加氢活性与金属颗粒上的高配位点有关.本文还与蒸氨法制备的样品进行了比较,发现在相同的实验条件下,蒸氨法样品在加氢反应中没有活性.Nicola Scotti Elisabetta Finocchio Claudio Evangelisti Marcello Marelli Rinaldo Psaro Nicoletta Ravasio Federica Zaccheria 2019Chinese Journal of Catalysis2019,40,11:0
