The paper presented an alloying/dealloying process for the fabrication of hierarchically porous alloy films (HPAFs). The fabrication process involved electrodeposition of copper on the substrate, annealing to produce new alloy phases, and selective dissolution of copper from the surface. Scanning electron microscopy (SEM) images suggested that the HPAFs were composed of large-sized ligament-channels...
Bi 2 WO 6 samples were fabricated by chemical solution decomposition (CSD) method and nanosheet-like Bi 2 WO 6 samples could be obtained by concentrated nitric acid treatment at 70°C for 20min. The products were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), and UV–vis diffuse reflectance spectra. Photocatalytic activities...
