Hexagonal Zn{sub 3}(OH){sub 2}V{sub 2}O{sub 7}·2H{sub 2}O nanoplates have been successfully synthesized via a facile and template-free hydrothermal method. The nanocrystals have a hexagonal shape with 650–750 nm in diameter and 120–140 nm in thickness. The possible mechanism of forming such hexagonal Zn{sub 3}(OH){sub 2}V{sub 2}O{sub 7}·2H{sub 2}O nanoplates may be due to its inherent anisotropic crystal structure. Magnetic hysteresis measurement indicates that the as-synthesized hexagonal Zn{sub 3}(OH){sub 2}V{sub 2}O{sub 7}·2H{sub 2}O nanoplates have weak ferromagnetic property at room temperature. Compared to the floriated-like nanostructured Zn{sub 3}V{sub 2}O{sub 7}(OH){sub 2}(H{sub 2}O){sub 2} synthesized by a hydrothermal route, the as-prepared hexagonal Zn{sub 3}(OH){sub 2}V{sub 2}O{sub 7}·2H{sub 2}O nanoplates exhibited a significant increase in the methylene blue (MB) photodegradation rate under UV irradiation. Highlights: • Hexagonal Zn{sub 3}(OH){sub 2}V{sub 2}O{sub 7}·2H{sub 2}O nanoplates was synthesized via a hydrothermal method. • Magnetic study indicates that the nanoplates are of weak ferromagnetic property at room temperature. • The nanoplates exhibit greatly enhanced activity in the UV-light photocatalytic degradation of methylene blue.
