• develop low-cost FeC@N-C catalysts with high catalytic performance is desirable to replace the conventional PGM-based ORR and OER catalysts. Bimetallic Prussian blue analogues (PBAs) are metal organic framework (MOF) materials, which are promising precursors to prepare transition metal carbides with a

• +/Li. Results and Discussion The overall process of synthesizing NiFe-PBA/PP-T is schematically illustrated in Figure 1. Initially, the freshly cut pomelo peel was mixed with Na3C6H5O7, Ni(NO3)2, and K3[Fe(CN)6] to form bimetallic Prussian blue analogues with a MOF structure at room temperature. Ni3[Fe

•  2a shows that the Prussian blue analogues formed on the surface of PP have a well-defined cubic shape with an uniform particle size distribution. The particle size was approx. 80 nm. These cubic particles were made out of many small particles and many cavities were observed on the surface. SEM images

• monolayers fabricated through sol–gel chemistry were used to grow isolated particles of Prussian blue analogues (PBA). The elaboration of the TiO2/CoFe PBA nanocomposites involves five steps. The samples were characterized by scanning electron microscopy (SEM), atomic force microscopy (AFM), infrared

• . Keywords: nanopatterning; nanoperforated oxide monolayer; Prussian blue analogues; Introduction The development of methods to place nanoparticles into spatially well-defined, ordered arrays is one challenging aspect of nanotechnology. This is usually achieved by using top-down approaches, implementing
