Herein, we report the facile synthesis, characterization and visible-light-driven photocatalytic degradation of perforated curly ZnNiO nanosheets synthesized by hydrothermal process. The X-ray diffraction (XRD) and scanning electron microscopy (SEM) studies confirmed the cubic phase crystalline structure and growth of high density perforated curly ZnNiO nanosheets, respectively. As a photocatalyst, using methylene blue (MB) as model pollutant, the synthesized nanosheets demonstrated a high degradation efficiency of ~76% in 60 min under visible light irradiation. The observed results suggest that the synthesized ZnNiO nanosheets are attractive photocatalysts for the degradation of toxic organic waste in the water under visible light.
在此，我们报告了通过水热法合成的多孔卷曲状ZnNiO纳米片的简便合成、表征及可见光驱动的光催化降解性能。X射线衍射（XRD）和扫描电子显微镜（SEM）研究分别证实了立方相晶体结构和高密度多孔卷曲状ZnNiO纳米片的生长。作为光催化剂，以亚甲基蓝（MB）为模型污染物，合成的纳米片在可见光照射下60分钟内表现出约76%的高降解效率。观察结果表明，合成的ZnNiO纳米片是用于可见光下降解水中有毒有机废物的有吸引力的光催化剂。
