摘要: Abstract Pore-regulating reagents (PRAs) affect the porous structure of silica-rich silica-alumina gels because their charge density and intensity. PRA molecules containing nitrogen have a particularly strong effect. Any desired mean pore size in range 7.5 to 40 nm can be achieved by selecting an appropriate PRA. Porosity may controlled without substantial loss specific surface area.
