Prussian blue (PB) and Prussian blue analogues (PBAs) are commonly synthesized by conventional methods, such as chemical precipitation, thermal decomposition, and electrochemical deposition. Herein, we have successfully synthesized Prussian blue by oxidative print light synthesis (PLS) with a cubic Fe₄[Fe(CN)₆]₃ phase, as confirmed by XRD compared to pure Prussian blue. Furthermore, UV–vis, FT-IR, Raman, and XPS measurements also present experimental evidence of PB formation from the Potassium hexacyanoferrate(II) trihydrate precursor by PLS. STEM images display aggregated PB particles of ca. 500 nm with a homogeneous distribution of Fe, N, C, and K throughout the sample. The electrochemical characterization provides excellent electrocatalytic performances during the charge and discharge processes, with oxidation/reduction reactions of high- and low-spin iron, which is already known as the interconversion of Prussian white to Prussian blue (PW ⇄ PB) and Prussian blue to Prussian green (PB ⇄ PG), respectively. In particular, PLS has been successfully employed as a smart and low-cost protocol to synthesize thin Prussian blue films, and possibly other PBAs, for applications in energy storage devices such as K, Na, and Mg ion batteries.

普鲁士蓝的氧化印刷光合成薄膜沉积

普鲁士蓝（PB）和普鲁士蓝类似物（PBA）通常通过常规方法合成，例如化学沉淀，热分解和电化学沉积。在这里，我们已经成功地通过立方氧化铁Fe ₄ [Fe（CN）₆ ] _3的氧化印刷光合成（PLS）合成了普鲁士蓝XRD证实，与纯普鲁士蓝比较 此外，UV-vis，FT-IR，拉曼和XPS测量也提供了PLS由三水合六氰合铁酸钾（II）前体形成PB的实验证据。STEM图像显示约PB的聚集PB颗粒。500 nm，整个样品中Fe，N，C和K均匀分布。电化学特性在充放电过程中提供了出色的电催化性能，具有高自旋和低自旋铁的氧化/还原反应，这已被称为普鲁士白到普鲁士蓝（PW⇄PB）和普鲁士蓝的互变。普鲁士绿色（PB⇄PG）。特别是，PLS已成功地用作一种智能且低成本的协议，用于合成普鲁士蓝薄膜以及可能的其他PBA，
