Anisotropic colloidal quasi-two-dimensional (2D) hybrid nanoplates (HNPLs) of inorganic-organic zinc selenide (ZnSe center dot 0.5N(2)H(4)) and zinc selenide doped manganese (ZnSe:Mr center dot 0.5N(2)H(4)) have been fabricated by one-step solvothermal synthesis in a binary solution of distilled water and hydrazine under microwave irradiation at atmospheric and high pressure versus conventional heating. The structure, morphology and compositions of the ZnSe.0.5N(2)H(4) and ZnSe:Mn.0.5N(2)H(4) HNPLs were characterized by TEM and SEM analyses, X-ray diffraction, FT-IR, UV-vis spectroscopy and BET analysis. The as-prepared ZnSe center dot 0.5N(2)H(4) and ZnSe:Mr center dot 0.5N(2)H(4) 2D HNPLs in microwave reactor at high pressure conditions have been highly crystallized single crystals with the thickness of a range of 15-30 nm, side length of 200-300 nm and width of 100-150 nm. SEM analysis shows that the further surface modification of ZnSe:Mn center dot 0.5N(2)H(4) 2D HNPLs with octadecanoic acid provides more regular and narrow structures of nanocrystals. Additionally, the photocatalytic degradation of Rhodamine 6G (R6G) solution using ZnSe center dot 0.5N(2)H(4) and ZnSe:Mn center dot 0.5N(2)H(4), 2D HNPLs as photocatalysts under ultraviolet (UV) irradiation is investigated.
