Habka isku-dhafka shaandhada molecular, wakiilka template ayaa door muhiim ah ka ciyaara. Wakiilka template waa molecule organic ah oo hagi kara kobaca crystal ee shaandhada molecular iyada oo loo marayo isdhexgalka intermolecular oo go'aaminaya qaabdhismeedkiisa ugu dambeeya.
Marka hore, wakiilka template wuxuu saameyn karaa habka isku-dhafka ee shaandhada molecular. Habka isku-dhafka ah ee shaandho molecular, wakiilka template waxaa loo isticmaali karaa "hage" si uu u caawiyo shaandheynta shaandho molecular leh cabbir iyo qaab gaar ah. Tani waa sababta oo ah wakiilka template ayaa awood u leh inuu aqoonsado oo isku dubbarido noocyada silicate ee aan noolayn ee gaarka ah, si uu u xakameeyo jihada koritaanka iyo heerka. Marka labaad, wakiilka template wuxuu sidoo kale saameyn karaa xajmiga daloolka iyo qaabka shaandhada molecular.
Shaandhooyin molecular oo leh cabbirro dalool kala duwan iyo qaabab ayaa lagu soo saari karaa wakiillo template kala duwan, sababtoo ah cabbirka molecular iyo qaabka wakiilka template ayaa go'aaminaya xajmiga daloolka iyo qaabka shaandho molecular final.
Tusaale ahaan, template decyl waxaa loo isticmaali karaa in lagu farsameeyo ZSM-5 shaandho molecular oo leh qaab dhismeedka cyclopore toban ka kooban, halka template dodecyl loo isticmaali karo in lagu dhejiyo ZSM-12 shaandho molecular oo leh qaab-dhismeed cyclopore ah oo laba iyo toban xubnood ah.
Intaa waxaa dheer, wakiilka template wuxuu sidoo kale saameyn karaa aashitada iyo xasiloonida shaandhada molecular. Noocyada kala duwan ee wakiilada template waxay siin karaan aysidhka kala duwan si ay u shaandheeyo molecular, sababtoo ah wakiilka template waxa uu la macaamili karaa xarunta acidic ee shaandho molecular iyada oo loo marayo kooxaha ay functional.
Isla mar ahaantaana, wakiilada template kala duwan waxay sidoo kale saameyn karaan xasiloonida kulaylka iyo xasilloonida kuleylka ee shaandho molecular. Tusaale ahaan, isticmaalka template amide waxay si weyn u wanaajin kartaa xasiloonida kulaylka ee shaandhada molecular ee ZSM-5.
Gebogebadii, wakiilka template wuxuu door muhiim ah ka ciyaaraa isku dhafka ZSM shaandho molecular.
Adiga oo dooranaya wakiilka template ku habboon, shaandhooyin molecular oo leh cabbir dalool gaar ah iyo qaab, aysidhka wanaagsan iyo xasilloonida ayaa la soo saari karaa, si ay si fiican u daboolaan baahiyaha dareen-celinta catalytic ee kala duwan.
