Silica catalysts o loʻo i ai le tele o tulaga lelei i gaioiga faʻamaʻi ona o le lapopoa o le pore ma le maualuga o le vaega o luga. Muamua, o la latou pore lapoa e faafaigofie ai le faʻasalalauina o faʻamaʻi catalytic, ma faʻateleina ai le tali atu ma le filifilia. Lona lua, silica catalysts e chemically inert ma e le faia ni faʻamatalaga faʻapitoa faʻatasi ma reactants, faʻaitiitia ai le tali filifilia ma fua. E le gata i lea, o silica catalysts e faigofie ona faʻaoga ma saunia, e taʻitaʻia ai lo latou faʻaogaina lautele.
