Enhancement of magnetic, electrochemical and photocatalytic properties of lead hexaferrites with coating graphene and CNT: Sol-gel auto-combustion synthesis by valine

PbFe12O19 nanocomposites are successfully synthesized by sol-gel auto-combustion route by employing valine as reducing agent and graphene and CNT as matrix. The magnetic property of the products is investigated. The lead hexaferrite nanocomposites with high coercive force of 5698 Oe are obtained in the presence of graphene. For the first time, the photocatalytic behavior of lead hexaferrites is evaluated, using the degradation of organic dyes...
