Abstract

Using different divalent metals (for example, M2 + = Zn2 +, Mg2 +, Co2 +, Ni2 +), trivalent (for example, M3 + = Al3 +, RE3 +, Cr3 +, Ga3 +, Mn3 +) and tetravalent ( for example, M4 + = Ti4 +, Ce4 +), Layered Double Hydroxides (LDHs) with photocatalytic properties can be synthesized. ThiUsing different divalent metals (eg M2 + = Zn2 +, Mg2 +, Co2 +, Ni2 +), trivalent (eg M3 + = Al3 +, RE3 +, Cr3 +, Ga3 +, Mn3 +) and tetravalent (eg M4 + = Ti4 +, Ce4 +), Hydroxides Lamellar doubles (LDHs) with photocatalytic properties can be synthesized. This project seeks to identify new metallic cations with photocatalytic activity capable of partially or totally replacing Zn, Al and or RE (probably Eu and Tb) in flat LDHs. Then, after preparing and mastering the synthesis of flat LDHs with possible photocatalytic properties, different morphologies can be tested to verify improvements in the performance of this material for applications in photocatalysis.s project seeks to identify new metallic cations with photocatalytic activity capable of partially or totally replacing Zn, Al and or RE (probably Eu and Tb) in the original ZnAl LDHs.
