Nanotechnologies are currently envisaged to revolutionize medicine, manufacturing, energy production, and other fundamental features of everyday life in the 21st Century.
Nanomaterials are very promising for enhancing device performances for sensing, sustainable energy production, and energy conversion and storage, as extensively reported in the literature. In this field, one of the most severe challenges is to find suitable methods for fabricating nanomaterials. Over the years, numerous preparation methods have been proposed in the literature, but not all of them are easily scalable and economically advantageous for industrial application. In this context, electrochemical deposition in a template is a facile method for fabricating either two- or one-dimensional nanostructured materials because it allows easily adjusting the fundamental parameters controlling their final features. In addition, electrochemical processes are usually cheap and environmentally friendly, and they can be easily scaled up from lab to industrial level. For these reasons, different electrodeposition methods were studied (galvanic deposition, galvanostatic, potentiostatic, and cyclovoltammetric deposition) for the synthesis of different types of nanomaterials for application in electrochemical sensing, in batteries (lead–acid, lithium–ion, and so on), in solar cells, and in electrochemical water splitting. Further, nanotechnology is advantageous for improving the performances of electrochemical devices. The use of nanostructured materials is in fact a strategy employed by several researchers because electrochemical activity strongly depends on the electrode surface area, which is one of the principal characteristics of the low sized materials. In fact, a high specific surface ensures a complete utilization degree of the electroactive area of the nanostructured device. In addition, in the case of electrodes with ordered arrays of nanowires or nanotubes, the spatial orientation/arrangement of array and the corresponding interactions between the neighboring nano-units have a large influence on the overall device performance.
