Abstract
Achieving the preparation of uniformly loaded ultrafine metal nanoparticles catalysts is a key problem in the field of catalysis. In this study, ultrafine gold nanoparticle catalysts were prepared by using conjugated microporous polymers (CMPs) modified with sulfhydryl group to support gold. High-resolution transmission electron microscopy (HR-TEM) at Au@TBD-S-SH showed that the average particle size of gold nanoparticles (Au NPs) was 3.4 nm. The higher catalytic activity was shown by comparing the normalized reaction rate constants (Knor = 117) from the work of other investigators. Moreover, the catalysts maintained their activity after ten cycles. Meanwhile, Au NPs increased in size probably on account of adsorption products and slight agglomeration. These studies demonstrated that functionalized CMPs loaded with noble metals can efficiently remove phenolic compounds from wastewater.
