Abstract
Highly dispersed Fe nanoparticles (NPs) were deposited on SiO2 NPs by atomic layer deposition (ALD) in a scalable fluidized bed reactor at 400 ºC. In CO oxidation reactions, over the Fe/SiO2 catalyst, Fe2O3 played a vital role. In a long-term stability test of more than 300 h of CO oxidation reaction, there was almost no activity decrease of Fe/SiO2 at 550 ºC.
