Type-II p(SnSe)-n(g-C3N4) heterostructure as a fast visible-light photocatalytic material: Boosted by an efficient interfacial charge transfer of p-n heterojunction

Pristine single-crystalline SnSe nanoparticle (NPs) and SnSe/g-C3N4 nanocomposites with a high efficient visible-light photocatalytic performance were synthesized by a co-precipitation method in an ambient condition. X-ray diffraction (XRD) patterns indicated an orthorhombic phase for all samples. In addition, the XRD patterns and transmission electron microscopy (TEM) images showed crystallite and particle sizes of the SnSe NPs were decreased...
