PAMAM催化剂的高催化性能和高重复利用率

SiO2@Pd-PAMAM 催化剂中Pd纳米尺寸为1.56 +/-0.67 nm，将其作为加氢反应的催化剂具有非常优越的性能。能有效的催化烯烃、炔烃、酮类、硝基等的加氢反应，表现出100%的转化率，和100%的选择性，与传统的Pa催化剂相比，催化性能提高一倍。此外SiO2@Pd-PAMAM 催化剂重复再利用5次还能保持原有的催化效率，几乎没有Pd的渗出并混到反应物中，而传统的Pa催化剂循环使用3次后就失去了其催化性能。威海晨源公司整理自《SilicaDendrimerCoreShell Microspheres with Encapsulated Ultrasmall Palladium Nanoparticles:Efficient and Easily Recyclable Heterogeneous Nanocatalysts》Ankush V.
