“…37,38 A wide range of methods have been used to synthesize cobalt-based nanostructures, including precipitation, vapor deposition, and wet chemical reactions. [39][40][41][42][43] Even though the use of these methods is growing rapidly, there is still a need to adopt facile approaches for the development of new generation electrocatalysts at a large scale while incorporating the simple, scalable and tunable features of the nanostructured materials to be prepared. According to the available literature, PdO nanoparticles have not been doped into CoSe 2 nanostructures via hydrothermal methods followed by UV light reduction.…”
