| Abstract: | Macroporous materials with three dimensional pores and channels are anticipated to exhibit improved performance in numerous applications such as photonic band gap crystals, battery electrodes and gas sensors due to their special structure. In this work, macroporous Cu2O thin films were prepared by template-assisted electrodeposition method. The mechanism of electrodeposition infiltrating procedures indicated that the target architectures can basically maintain its original shape, and the fabrication of spherical-porous shaped Cu2O controlled by crystalline structures is firstly studied systematically. The morphology of macroporous material along the (1 1 1) direction demonstrated that the target architecture can copy both the crystalline structures and the colloidal crystal template. Moreover, models are set up to discuss the evolution of the morphology (the shapes of the pore mouths and pore walls), which indicated that the pore mouths and pore walls were deeply influenced by the deposition depth. |
