Summary: RhZn intermetallic nanoparticles have been developed as an exceptional catalyst for efficient heterogeneous hydroformylation, showing high activity and selectivity compared to traditional homogeneous catalysts. Density functional theory calculations reveal that RhZn surfaces reduce the binding strength of reaction intermediates and have lower activation energy barriers, leading to more favorable reaction energetics. Additionally, potential catalyst design strategies for achieving high regioselectivity have been predicted.

Summary: In this study, a highly dispersed catalyst (Fe3O4/NFe) was prepared using Fe3O4 and natural goethite (NFe) for the removal of tetracycline in a heterogeneous Fenton-like system. The grinding method was used to destroy a large amount of =Si-O-Si on NFe, resulting in the production of SiO center dot on the surface. Fe3O4 nanoparticles were then grown on NFe, forming Fe-O-Si bonds. The Fe3O4/NFe catalyst showed excellent degradation performance for tetracycline and has the potential to replace traditional homogeneous Fenton methods.
