This work demonstrates a simple and versatile deep eutectic solvent (DES)-assisted synthesis of bullet-shaped cerium–zinc oxide (Ce–ZnO) and sheet-like cerium–zinc hydroxide nitrate (Ce–Zn5(OH)8(NO3)2·2H2O). DES could serve not only as a green solvent but also as a superior template to produce these two different hierarchically shaped materials. Interestingly, Ce–ZnO shows catalytic activity toward polymerization of dopamine to initially pink color quinone derivatives with the visible light absorption at 475 nm and finally to blue-emitting polydopamine with highest fluorescence intensity at 480 nm. The catalytic activity of Ce–ZnO can be selectively inhibited by pyrophosphate ions (PPi), which leads to a decrease in the absorbance intensity or fluorescence emission. PPi detection strategies were established, and the linearity was achieved from 0.5 to 100 μM with a low detection limit of 0.05 μM for the fluorometric detection, while the linear detection was 0.5–150 μM and the low detection limit was 0.19 μM for colorimetric detection. This work offers a new opportunity to produce Ce–ZnO and Ce–Zn5(OH)8(NO3)2·2H2O using an inexpensive and eco-friendly solvent, and provides a useful way of detecting PPi. Hence, from these findings, the proposed synthesis strategy is expected to serve as a novel green strategy for preparing hierarchically shaped materials.

子弹状氧化铈和片状氧化铈硝酸锌的深共晶溶剂介导合成：焦磷酸离子的比色和荧光检测
这项工作展示了一种简单而通用的深共晶溶剂 (DES) 辅助合成子弹形氧化铈 (Ce-ZnO) 和片状铈-氢氧化硝酸锌 (Ce-Zn 5 (OH) 8 (NO 3 ) 2 ·2H 2哦）。DES 不仅可以作为绿色溶剂，还可以作为生产这两种不同层次形状材料的优良模板。有趣的是，Ce-ZnO 对多巴胺聚合为最初在 475 nm 处具有可见光吸收的粉红色醌衍生物和最终在 480 nm 处具有最高荧光强度的蓝色发射聚多巴胺显示出催化活性。Ce-ZnO 的催化活性可以被焦磷酸根离子 (PPi) 选择性抑制，从而导致吸收强度或荧光发射的降低。建立了PPi检测策略，线性范围为0.5-100μM，荧光检测的检测下限为0.05μM，而比色检测的线性检测为0.5-150μM，检测下限为0.19μM。5 (OH) 8 (NO 3 ) 2 ·2H 2 O 使用廉价且环保的溶剂，为检测 PPi 提供了一种有用的方法。因此，从这些发现来看，所提出的合成策略有望作为一种新的绿色策略来制备分层形状的材料。
