Fundamental Insights into the Nucleation and Growth of Mg–Al Layered Double Hydroxides Nanoparticles at Low Temperature

Abstract

Nucleation and growth of the Mg–Al layered double hydroxide nanoparticles are controlled by varying the nucleation temperature in conjunction with a fast addition of metal precursor solution. Nanoparticles of the size between 20 and 200 nm are obtained, while avoiding the use of organic structure directing agents and forgoing aging process. Nanoparticles self-assembly in solution is discussed and correlated to the agglomeration process.
