我们合成了不溶性普鲁士蓝纳米粒子（PB NPs）和水溶性PB NPs（[Fe（CN）6]4−-modified PB NPs）作为Pt亚纳米团簇的合成场和载体。Pt ~（2+）可以吸附在它们的表面Fe-CN位上。在不溶性和水溶性PB NP表面上附着的Pt 2+的量饱和，分别达到Pt/Fe = 15和40摩尔%，基于PB的总金属离子。结果表明，Pt 2+在表面CN位上的吸附量受表面改性的控制。从TEM和STEM-HADDF-EDS的结果来看，在使用肼还原后，在水溶性PB NP上观察到Pt亚纳米簇（1.4nm）。
We synthesized insoluble Prussian blue nanoparticles (PB NPs) and water-soluble PB NPs ([Fe(CN)6]4−-modified PB NPs) as synthetic fields and carriers of Pt subnano clusters. Pt2+can attach on their surface Fe–CN sites. The amount of the attached Pt2+on the insoluble and water-soluble PB NP surfaces was saturated to reach Pt/Fe = 15 and 40 mol%, respectively, based on the total metal ions of PB. The results showed that the attachment amount of Pt2+on the surface CN sites was controlled by the surface modification. From results of TEM and STEM-HADDF-EDS, Pt subnano clusters (1.4 nm) were observed on water-soluble PB NPs after the reduction using hydrazine.
