A facile and green synthesis of Mn and P functionalized graphitic carbon nitride nanosheets for spintronics devices and enhanced photocatalytic performance under visible-light.

Manganese and phosphorus co-doped, graphitic carbon nitride (g-CN) nanosheet (Mn/P-g-CN) is prepared by facile and green calcination process of melamine (CHN), manganese chloride tetrahydrate (MnCl·4HO), and ammonium dihydrogen phosphate ((NH)HPO). The Mn/P co-doping significantly enhances magnetic values compared to pristine-g-CN, phosphorus-doped g-CN (P-g-CN), and manganese-doped g-CN (Mn-g-CN). We find that Mn/P-g-CN is a half-metallic ferromagnetic material having a magnetic moment and Curie temperature of 4.
