Nowadays it is still a great sustainable processes challenge to produce efficient, selective and easy magnetic recovery and recycling catalysts for oxidation of alcohols using air as the oxidant. In this work, a new magnetic nanohydrogel comprising [DABCO-allyl][Br] ionic liquid, allyl alcohol and N,N'-methylenebis(acrylamide) is used for stabilization of small and highly uniform palladium nanoparticles of 3–4 nm size [email protected] This material has been characterized by Fourier-transform infrared spectroscopy (FTIR), atomic adsorption spectroscopy (AAS), thermogravimetric analysis (TGA), transmission electron microscopy (TEM), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), SEM-Map, energy-dispersive X-ray spectroscopy (EDX), X-ray photoelectron spectra (XPS), vibrating-sample magnetometer (VSM) and dynamic light scattering (DLS). According to optimization of cross-linking degree and ratio of DABCO-IL, [email protected] is found as a highly selective catalyst in oxidations of primary alcohols to the corresponding aldehydes in toluene and to acids in water. Furthermore, secondary alcohols were reacted efficiently to the corresponding ketones in both toluene and water. Catalyst is magnetically recovered and recycled for several times in both toluene and water and the reused catalysts are characterized by TEM and XPS.

如今，使用空气作为氧化剂，生产高效，选择性和简便的磁性回收和再循环用于醇氧化的催化剂仍然是一个巨大的可持续过程挑战。在这项工作中，一种新型的磁性纳米水凝胶包含[DABCO-烯丙基] [Br]离子液体，烯丙醇和N，N'-亚甲基双（丙烯酰胺）用于稳定3–4 nm尺寸的小型且高度均匀的钯纳米颗粒[已通过电子邮件保护]该材料已通过傅里叶变换红外光谱（FTIR），原子吸收光谱（AAS），热重分析法进行了表征分析（TGA），透射电子显微镜（TEM），扫描电子显微镜（SEM），能量色散光谱（EDS），SEM图，能量色散X射线光谱（EDX），X射线光电子光谱（XPS），振动样品磁力计（VSM）和动态光散射（DLS）。根据DABCO-IL的交联度和比例的优化，发现[电子邮件保护]是伯醇氧化为甲苯中相应醛和水中酸的一种高度选择性的催化剂。此外，使仲醇在甲苯和水中有效地反应为相应的酮。催化剂可以在甲苯和水中进行磁回收和多次循环利用，并且通过TEM和XPS对重复使用的催化剂进行了表征。
