Electrochemical energy conversion systems such as fuel cells, electrolyzers, bateries and others, have received worldwide attention owing to their high energy density, security, low operating temperature, and low pollutant emission. Nonetheless, the commercial application of this systems still faces some critical obstacles: relatively high costs, insufficient performance and inadequate long-term durability of the electrocatalysts. To overcome these issues, various methods have been proposed by tailoring the design of the size, composition, and shape of the electrocatalytic materials. In this sense, 3D materials based on different metals, are an exceptional class of materials which are of interest for several high-performance applications thanks to their extraordinary physical properties such as extremely high porosity, high specific surface area, and extremely low density combined with very versatile synthesis approaches. In this talk, non noble metal 3D-structures, which combine the unique properties of metals such as excellent electrical and thermal conductivity and catalytic performance with the unique properties of common 3D-materials, will be thoroughly reviewed.
