Core-shell structures have been intensively studied in the last decades, mainly due to its great technological potential . Particularly, the first studies involving this core-shell system date back to the early 1990s. However, currently this field of research is highly diverse leading to obtained the different configurations, including multi-shells, yolk/shell and among others . In this case, it is well known that the formation of the core is due to the precursor, prioritizing the function of the target nanoparticle. Hence, this process starts mainly with the formation of the core and later the shell layer . Thus, the most commonly strategy used for the preparation of these materials with core-shell structure is based on a two or more step procedure . However, continuous hydro(solvo)thermal synthesis eliminates the need for multi-stage processes and has been widely used for the growth of core-shell structures .
