快速混合原位 XRD 揭示无添加剂 ZIF-8 纳米颗粒形成中的前驱体重组特征
Rapid-Mixing In Situ X-ray Diffraction Reveals Precursor-Reorganization Signatures in Additive-Free Zeolitic Imidazolate Framework-8 Nanoparticle Formation
AI 导读
研究将中心碰撞式微反应器与时间分辨原位 XRD 联用，在亚毫秒级微混合后以 5 s 时间分辨率追踪无添加剂水-甲醇体系中 ZIF-8 的形成，直接捕捉到晶体出现、表观结晶动力学和随后的晶格弛豫。
推荐理由
作者把中心碰撞式微反应器与时间分辨原位 XRD 联用，在亚毫秒混合后以 5 s 分辨率捕捉 ZIF-8 从无序前驱体到晶体的转变过程。
创新点
把亚毫秒微混合与 5 s 分辨原位 XRD 结合，在无添加剂条件下直接观测 ZIF-8 结晶前的无序前驱体演化，并给出晶格常数随生长收缩的弛豫证据。
