N2 - Environmentally friendly, high-quality layered K4Nb 6O17 crystals were easily grown by two different flux methods involving supersaturation, that is, flux evaporation and cooling of the solution. To fabricate them, potassium chloride (KCl) was chosen as the flux. Transparent and colorless plate-like layered crystals of K4Nb 6O17 were prepared with well-developed {010} faces of the orthorhombic system. The crystal sizes obviously depended on the evaporation loss (evaporation method), the holding temperature, and the cooling rate (cooling method). Transmission electron microscopy (TEM) images showed that the grown plate-like crystals were of a very good crystallinity. The major constituents were homogeneously distributed throughout them. The crystals exhibited good photocatalytic activity under ultraviolet light irradiation. Potassium chloride was found to be a very suitable flux for the environmentally friendly growth of photocatalytic K4Nb6O17 crystals.
