Catalytic nanostructures have seen a surge of interest in the past decade. With Scanning Electron Microscopy (SEM) and Energy Dispersive x-ray Spectroscopy (EDS), the surface area, topography, and composition of these nanostructures can be characterized. The accessibility of these instruments has generated interest involving the interactive effects of surface topography and catalytic activity of binary alloys. The research conducted involved electrodepositing, dealloying, and characterizing various nickel-copper binary alloys for methanol oxidation applications. By dealloying copper out of the sample through Controlled Potential Electrolysis (CPE), a high-surface nanoporous material was fabricated. Utilizing Cyclic Voltammetry (CV), the oxidation of methanol was analyzed before and after dealloying to determine whether porosity enhanced the catalytic efficiency. These samples were also characterized via SEM/EDS before and after dealloying.
