Microstructure of La-modified Al2O3 support with LaAlO3 nano-particles
Source abstract
Abstract
Lanthanum modified γ-alumina support that embedded highly dispersed LaAlO3 nano-particles in γ-alumina matrix were prepared by an impregnation process using aqueous lanthanum (III) nitrate. 5 mol% La added alumina was heated in the temperature range of 600-1200°C and characterized by surface area measurement, X-ray powder diffraction (XRD), scanning electron microscope (SEM), and transmission electron microscope (TEM). The added lanthanum should react with γ-Al2O3 to form LaAlO3 nano-particles in the secondary particle of alumina. LaAlO3 nano-particles with an average crystallite size of about 11 nm were found after heat treatment at 800°C, and the crystallite size of LaAlO3 nano-particles increased with the rise of heat treatment temperature.
