Heterogeneous Fenton-like reaction is a promising process for refractory wastewater treatment. Among the various heterogeneous Fenton-like catalysts, Prussian blue (PB) and Prussian blue analogues (PBAs) show great potential for hydrogen peroxide and persulfate activation owing to their low toxicity, simple preparation, and high activity. To further improve the catalytic activity of PBAs and their derivatives (PBDs), many efforts have been made to overcome the instability of the crystal structure and develop feasible methodologies to prepare PBAs/PBDs with diverse morphologies and compositions. In this Account, our recent achievements on novel synthetic strategies to obtain PBAs/PBDs with controlled morphologies, geometric sites, and electronic structures were systematically summarized. The physicochemical properties of the PBAs/PBDs and their contribution to the catalytic reaction in the advanced oxidation processes (AOPs) were also discussed.

普鲁士蓝类似物及其衍生物：从精细的微观结构设计到增强的芬顿类应用


非均相类芬顿反应是难降解废水处理的一种有前景的工艺。在各种非均相类芬顿催化剂中，普鲁士蓝（PB）和普鲁士蓝类似物（PBAs）由于毒性低、制备简单、活性高，在过氧化氢和过硫酸盐活化方面显示出巨大的潜力。为了进一步提高PBA及其衍生物（PBD）的催化活性，人们做出了许多努力来克服晶体结构的不稳定性，并开发可行的方法来制备具有不同形貌和组成的PBA/PBD。在这篇文章中，我们系统地总结了我们最近在获得具有受控形态、几何位点和电子结构的 PBA/PBD 的新型合成策略方面取得的成就。还讨论了 PBA/PBD 的物理化学性质及其对高级氧化过程（AOP）中催化反应的贡献。
