Synthesis of NdFeO_3 Perovskites in A Reverse Microemulsion and Its Visible Light Photocatalytic Activity

摘要

The synthesis of NdFeO_3 perovskites in a reverse microemulsion and its photocatalytic property for visible light degradation reaction of methylene blue were investigated, respectively. When the irradiation time prolonged from o to 90 minutes, the degradation rate for methylene blue could achieve 60%. XRD pattern shows that a well-crystallized perovskite structure is observed for the NdFeO_3 sampled prepared. The TEM characterization result indicates that the dimension of NdFeO_3 nanopowders is in the range of 35～45 nm, which is consistent with the calculation result using the Scherrer equation.
