A molecular catalyst, (sal)MoVI, and a heterogeneous catalyst, either Pd or Au nanoparticles (NPs), were integrated into one UiO-66 MOF microcrystal. The resulting dually functionalized catalysts, [email protected](sal)Mo and Au/UiO-66-(sal)Mo, have been utilized for a one-pot tandem reaction of H2O2 generation and selective liquid-phase alkene oxidation. The NPs serve as catalysts for the production
将分子催化剂(sal)Mo VI和非均相催化剂Pd或Au纳米颗粒(NPs)集成到一个UiO-66 MOF微晶中。所得的双官能化催化剂[电子邮件保护的](sal)Mo和Au / UiO-66-(sal)Mo已用于H 2 O 2生成和选择性液相烯烃氧化的一锅串联反应。NP用作由H 2和O 2产生H 2 O 2的催化剂(sal)Mo部分起氧化催化剂的作用。当金属NP被完全封装在MOF微晶中时,烯烃氢化副反应被大大抑制,5-溴-1-环辛烯的氢化/氧化产物比降低6倍,有利于环氧化物作为主要产物。对于Au / UiO-66-(sal)Mo,其中两种催化剂都紧靠MOF微晶,与[ Au / UiO-66-NH 2 + UiO -66-sal(Mo)]两个单官能化MOF的物理混合物。
