Preparation of iron (III) oxide nanoparticles using a mesoporous carbon nitride template for photocatalytic phenol removal

In this study, mesoporous carbon nitride (mp-C 3 N 4 ) was used as a novel removable template to prepare iron (III) oxide (Fe 2 O 3 ) nanoparticles. Without the template, the formed Fe 2 O 3 has micrometer size, while using the mp-C 3 N 4 template led to the formation of Fe 2 O 3 nanoparticles. The...

Description
Summary:In this study, mesoporous carbon nitride (mp-C 3 N 4 ) was used as a novel removable template to prepare iron (III) oxide (Fe 2 O 3 ) nanoparticles. Without the template, the formed Fe 2 O 3 has micrometer size, while using the mp-C 3 N 4 template led to the formation of Fe 2 O 3 nanoparticles. The prepared Fe 2 O 3 nanoparticles showed comparable high crystallinity to the Fe 2 O 3 sample prepared without template. It was confirmed that all samples prepared using mp-C 3 N 4 template showed better photocatalytic activity than the bulk Fe 2 O 3 . Total removal of phenol (100%) can be achieved after 15 h on the Fe 2 O 3 samples prepared at 973 K using mp-C 3 N 4 with pore sizes of 7 and 12 nm, while only ca. 30% was observed on the bulk Fe 2 O 3 . It was suggested that the smaller the particle size, the shorter the diffusion length of electron to migrate to the surface, resulted in the lower electron-hole recombination that would lead to the higher photocatalytic activity.
