中文摘要：

采用改进的缓释共沉淀法成功合成了红细胞状钼酸钙分级结构,通过X射线衍射（ XRD）、傅立叶红外光谱（ FT-IR）、拉曼光谱（ Raman）和扫描电子显微镜（ SEM）对其结构和形貌进行了表征。进行了一系列条件实验,包括钼源、溶液的pH和反应时间等。研究发现,MoO42-释放速度对合成产物形貌的形成起着重要作用,提出了缓释策略和定向生长机理。此外,红细胞状CaMoO4在536 nm处呈现了一个强而宽的荧光发射峰；对有机染料亚甲基蓝显示了较高的吸附去除率和结构稳定性,展示了在污水处理方面有潜在应用前景。

英文摘要：

In this paper, erythrocyte-like calcium molybdate （ CaMoO4 ） hierarchical structures are successfully synthesized by a modified slow-release strategy. The structure of the as-prepared products is characterized by X-ray diffraction, Fourier transform infrared and Raman spectroscopy. The morphology is observed with scanning electron microscopy. A series of experiments of reaction conditions including reaction time, initial pH and molybdenum source are carefully carried out. The results show that the slow release of MoO2-4 plays a key role in the morphology of the products. Moreover, the photoluminescence spectrum of the erythrocyte-like CaMoO4 reveals a strong and broad emission peak at 536 nm. The erythrocyte-like CaMoO4 exhibits high removal rate for the Methylene Blue （ MB） , suggesting its potential application in water treatment.
