Engineering the shape, size and composition of functional nano-materials is a powerful tool to improve their properties and enhance their performance. In the past decade, considerable research efforts have been devoted to produce metallic (Au, Pt, Pd, Ni, Co, Fe) and ceramic ( Cu2O, CuO, SiO2, ZnSnO3, CaTiO3) hollow nanoparticles. We present an overview on the synthesis methods to create hollow cubic nanostructures and their related potential applications against other common structures of the same composition. We have classified the synthesis procedures into four main categories: 1) galvanic replacement, 2) template removal, 3) etching and 4) Ostwald ripening. Thereafter, we discuss their useful applications in catalysis, Li-ion batteries and medical treatments. In this discussion the potential superiorities of these complex nanostructures are particularly highlighted. Finally, we discuss the main challenges for creating these materials and conclude by describing the main research paths to design functional cubic hollow nanostructures.
