Facile fabrication of mesoporous α-Fe2O3/SnO2 nanoheterostructure for photocatalytic degradation of malachite green

The mesoporous structures of α-Fe2O3/SnO2 nanoheterostructure materials were clearly observed in the TEM micrographs and pore-diameter distribution plot. This mesonanoheterusture was tested for the photodegradation of malachite green.
