It is known that the physicochemical properties of the advanced materials are altered by changes in the physical parameters like particle size, morphology, composition, structure, and imperfections (at short-, medium-and long-range) . These parameters are, in turn, strongly dependent on processing conditions, which can lead to obtaining advanced materials with more or less defects depending on its desired application . Currently, strategies focused on solution-based synthesis have attracted great attention over everything in processing of a wide variety of advanced materials, since such strategies provide precise control of the desired physical parameters . Among these solution-based methods, the hydrothermal synthesis stands out for its popularity related simple, effective and low cost preparation of a huge variety of advanced materials (organic, inorganic or hybrid) with controlled particle sizes and welldefined morphologies . Such advanced structures, are usually obtained through heterogeneous reactions above 100 °C and 1 bar in aqueous medium, or applying different solvents (in this last case, this process can also be conveniently called solvothermal) . Therefore, in this review, we will apply the term hydro(solvo)thermal more often.
