• formation of pure-phase BiFeO3 materials [19][22][23][24][34][35]. A proposed solution to control particle growth and to guarantee the formation of pure phases is the use of a nanocasting technique [36][37][38]. Here, previously synthesized mesoporous matrices act as sacrificial rigid molds, also known as

• structural directing agents (SDAs) [97][98]. This way, the final material corresponds to the negative replica of the SDA. There are two principal templating methods: hard templating (or nanocasting) and soft templating [97]. Hard templating involves an exotemplating approach, where the precursor solidifies

The synthesis of nanocomposites can be achieved in a variety of different ways, such as nanocasting or self-assembling templates [2][3

• basic pH, as SiO2 is not formed. Furthermore, during calcination, the nanocasting of Mg–Al species can occur on the mesoporous surface of the SBA-15 [9]. Indeed, the Mg–Al hydrotalcite becomes a magnesium–aluminum mixed oxide (Mg–Al–O) nanoparticles with thermal treatment and the average wall thickness

• adsorbed is favored by the Mg–Al oxide nanocasting improving the water affinity on the composite surface. This can be more visualized by the results showed for sample (Mg/Al)/SBA prepared by the in situ method, which retains 14.5 mmol of H2O/gcomposite, almost three times more water than the calcined
