Perovskites surface area/porosity

Unfortunately, the surface area and porosity of perovskites are insignificant compared to many of the mesoporous oxides. Because of this, an advanced interaction of reactants with the active sites of the catalysts is limited. To overcome this, various attempts were made to synthesize perovskite oxides with high surface areas using different methods such as the decomposition of metal complexes, the sol-gel, or the surfactant-assisted sol-gel and polymerized complex methods. 

The advantage of this strategy is that the synthesis of the porous materials takes place in a confined space formed by the porosity of the template. Thus-synthesized perovskite has a high surface area with three-dimensional ordered mesoporous channels, which can not be achieved by conventional methods. Moreover, template-based growth is commonly a solution or colloidal dispersion based process. It is less expensive and readily scalable to mass production. It also offers the advantages of less contamination and is environmentally benign. [34]...
