Rapid Combustion Synthesis of Metal Oxides Species Highly Dispersed on Layered Silicate Magadiite

Abstract

The good dispersion of metal oxides (MOs) with ultra‐small particles on host materials is essential for improving the utilization efficiency and increasing the service life. Herein, a novel strategy is developed as a methodology to synthesize MOs species highly dispersed on layered silicate magadiite by a rapid combustion method within 30 s. The speediness of the combustion process can avoid the agglomeration of MOs and well‐defined layered structure can further restrict the growth of nanoparticles. Thus, the lamellar structure of magadiite is well‐kept and MOs species with the particle size less than 5 nm immerse on the lamellar platelets. The results demonstrate this process can be considered as a methodology to synthesize different MOs species highly dispersed on various host materials for high efficiency applications.

Progress in Development of Magadiite to Produce Multifunctional Lamellar Materials

“…Further examples of hybrid magadiites formed in situ with complex ions can be found in a review article, which highlights the current situation regarding the modification of layered alkaline silicates with inorganic species to obtain functional inorganic−inorganic hybrid materials. 47 More recently, the ion exchange method has been explored for the preparation of several magadiites, using complex ions 35 or metal cations, such as Mn, 73 V, 40 K, Ca, Mg, 8 Co, Ni, Cu, 75,76 Fe, 77 Sn, 38 and Zn. 65 It should be noted that the insertion position of these metallic species can generate unique or improved properties, including adsorption, 8 absorption, 10 redox behavior, 38 optical and magnetic properties, 40 and the potential for catalytic applications.…”
