N'ime usoro njikọ nke sieve molecular, onye na-ahụ maka ndebiri na-arụ ọrụ dị oke mkpa. Onye na-ahụ maka ndebiri bụ molekul organic nke nwere ike iduzi uto kristal nke sieve molekul site na mmekọrịta intermolecular wee chọpụta nhazi kristal ikpeazụ ya.
Nke mbụ, onye ọrụ template nwere ike imetụta usoro njikọ nke sieve molecular. N'ime usoro njikọ nke sieve molecular, enwere ike iji onye nnọchi anya template mee ihe dị ka “nduzi” iji nyere aka mepụta sieve molekụla na nha na udi ya. Nke a bụ n'ihi na onye na-ahụ maka ndebiri nwere ike ịmata na ịhazi ụdị silicate inorganic kpọmkwem, si otú a na-achịkwa ntụzịaka na ọnụego ha na-eto eto. Nke abuo, onye na-ahụ maka ndebiri nwekwara ike imetụta nha pore na ọdịdị nke sieve molecular.
Enwere ike ịmepụta sieves molecular nke nwere nha na nha dị iche iche na ụdị ndebiri dị iche iche, n'ihi na nha molekụla na ọdịdị nke onye na-ahụ maka ndebiri na-ekpebi nha pore na ọdịdị nke sieve molekụla ikpeazụ.
Dịka ọmụmaatụ, enwere ike iji template decyl mee ihe iji mepụta ZSM-5 molecular sieve na usoro cyclopore nke nwere iri, ebe enwere ike iji template dodecyl mee ka ZSM-12 molecular sieve na-arụ ọrụ cyclopore iri na abụọ.
Na mgbakwunye, onye nnọchi anya template nwekwara ike imetụta acidity na nkwụsi ike nke sieve molecular. Ụdị ndebiri dị iche iche nwere ike inye acidity dị iche iche na sieve molecular, n'ihi na onye na-ahụ maka template nwere ike imekọrịta ihe na etiti acidic nke molecular sieve site na otu ọrụ ya.
N'otu oge ahụ, ndị ọrụ template dị iche iche nwekwara ike imetụta nkwụsi ike nke okpomọkụ na nkwụsi ike nke hydrothermal nke sieve molecular. Dịka ọmụmaatụ, iji template amide nwere ike melite nkwụsi ike ọkụ nke sieves molecular ZSM-5.
N'ikpeazụ, onye ọrụ template na-arụ ọrụ dị mkpa na njikọ nke ZSM molecular sieve.
Site na ịhọrọ onye na-ahụ maka template kwesịrị ekwesị, sieves molecular nwere oke nha na udi ya, enwere ike ịhazi ezigbo acidity na nkwụsi ike, ka ọ dị mma izute mkpa nke mmeghachi omume catalytic dị iche iche.
