Photocatalysis: progress using manganese-doped hematite nanocrystals†
Abstract
Manganese-doped hematite nanocrystals were synthesized by hydrothermal method and study on the activity of photocatalytic properties by different Mn ratio. From the crystal structure and optical study, the oxidation state of the manganese-doped hematite crystals was modulated by doping. The activity of samples (M1–M3) was tested by photodegradation of methyl orange dye in the presence of manganese-doped hematite as photocatalyst.
