We report a new, simple strategy to apply honeycomb films for the patterning of colloidal particles. By combination of a “bottom‐up” breath figure method and the electrochemical properties of the honeycomb films of ferrocenyl‐based oligomers, highly ordered hybrid membranes coated with ring‐like patterning of 0D‐ and 1D‐Ag nanoparticles (NPs) have been fabricated. One interesting phenomenon is that the nucleation and adsorption of Ag dots occurred preferentially at the edges of the micropores. The hybrid membranes exhibited richly electrochemical activities towards reduction of iodate and enhanced effectively catalytic reduction of organic dyes. We believe that this method can be used to decorate and/or assemble functional metal NPs such as Au, Pd, and Cu on honeycomb‐patterned materials for the further applications of photonics, sensors, and catalysis.
