Morphology on 3D ordered macroporous metals associated to deposition depth

High quality three-dimensionally (3D) ordered macroporous FeNi has been fabricated using the electrodeposition method assisted by colloidal crystal templates. The architectures are composed of highly ordered close-packed spherical pores interconnected. The material of this characteristic structure has potential applications in the fields of catalysts, electrodes, and sensors. The morphology of 3D ordered macroporous metals along the (1 1 1) direction is determined by the deposition depth (film thickness). In this work, the observed surface morphology is discussed in terms of subsequently increasing film thickness. Models are set up to help with full understanding of the evolution of the morphology (the shapes of the pore mouths and pore walls).
