Simultaneous precipitation and discharge plasma processing for one-step synthesis of α-Fe 2 O 3 -Fe 3 O 4 /graphene visible light magnetically separable photocatalysts
A novel facile combination of precipitation and plasma discharge reaction is successfully employed for one-step synthesis of an α-Fe O -Fe O graphene nanocomposite (GFs). The co-existence and anchoring of hematite (α-Fe O ) and magnetite (Fe O ) nanoparticles onto a graphene sheet in the as synthesi...
