Abstract: Abstract Amorphous silica-aluminas with enhanced Bronsted acidity have been successfully synthesized via a novel acetic acid based sol-gel process. The resulting amorphous silica-aluminas possess an irregular spherical morphology, homogeneously element dispersion, and a high external… read more here.
