Ko ngā tātari ngota – he rauemi tioata me ngā pūwero rite te rahi, rite tonu ki te rahi o te ngota – he mea tino nui i roto i te ahumahi hou, e āhei ai te wehewehe nui, te purenga, me ngā tauhohenga whakaterenga. Ahakoa he pai te mahi a ngā tātari tuku iho "kua oti te hanga", kei te puta he panonitanga nui: te pikinga ake o ngā Tātari Ngota Whakaritenga. Ka neke atu tēnei tauira i ngā āhuatanga rauemi tūturu ki te hangarau tika, āta whakaarohia o te hoahoa me te matū o te tātari hei whakatau i ngā wero motuhake, uaua e kore e taea e ngā otinga whānui te whakatika.
He aha te Whakaritenga? Ngā Āheinga Matua
Kei te panaia e ngā ahumahi ngā rohe, me te tono kia kore e kitea he parakore, kia whai hua i roto i ngā tukanga e nui ana te kaha, kia puta he ara matū hou, me ngā otinga mō ngā raruraru taiao uaua. Kāore i te eke ngā tātari paerewa, he maha ngā wā ka herea e ngā rahi pūngao pumau, ngā āhuatanga matū, te ngawari rānei ki te poke. Ka arohia e te whakaritenga ngā hiahia pēnei i te wehewehe i ngā ngota tata-rite (hei tauira, ngā isomers xylene motuhake), te whakakorikori i ngā tauhohenga tino whiriwhiri me te iti o te para, te whakahaere i ngā rauemi matū uaua, poke rānei, me te whakatutuki i ngā tono ahurei o ngā tono hou pēnei i te hopu waro, te purenga hauwai matatau rānei.
Te Kete Taputapu a te Kaihoahoa Ngoikore: Te Whakarite i te Hanganga
He mahi matatau o te pūtaiao rauemi me te matū te hanga i tētahi tātari ngota motuhake, e uru ana ki te whakahaere tika i ētahi tawhā matua:
Te Rahi me te Āhua o ngā Pūwero: Te mahi matua. Mā ngā tikanga hangahanga ka taea te whakahaere i te whānui o ngā pūwero (te tauine iti-nanometer ki te nanometer) me te āhua (ngā awaawa, ngā whare herehere). Mā tēnei ka tino whakatau ko ēhea ngā ngota ka taea te tomo, te horapa, me te taunekeneke, ka taea ai te wehewehe i ngā ranunga kāore i taea te wehe i mua, te whakaterenga rānei i te whiriwhiri āhua.
Te Hanganga o te Anga: Mā te neke atu i ngā aluminosilicates tawhito (zeolites), mā te whakauru i ngā huānga pēnei i te titanium, te tin, te germanium, te phosphorous rānei (te hanga aluminophosphates – AlPOs, silicoaluminophosphates rānei – SAPOs) ka tino whakarerekē i te whanonga matū. Ka whakatikatikahia e tēnei te momo (Brønsted/Lewis) me te kaha o te waikawa/pūtake, he mea nui mō te mahi whakatere me te whiriwhiri.
Matū me te Mahi a te Mata: Mā te whakarerekē i ngā mata o roto o ngā pūwero i muri i te hanganga ("tāpiri"), i te wā rānei o te hanganga ka whakaurua mai he rōpū rauropi motuhake, he matatini whakarewa, he matūriki nano rānei. Ka tāpirihia e tēnei he pae whakatere, ka whakarerekē i te kaha o te adsorption (hei tauira, ka hanga i ngā mata kia kore e pai te wai), ka taea rānei ngā mahi hou pēnei i te wehenga chiral.
Te Pūngao Hierarchical: Mā te whakakotahi i te pūngao iti (ngā pūngao iti) me ngā pūngao meso-, macro rānei kua whakauruhia, ka hangaia he whatunga kawe maha-taumata. Ka tino whakapai ake tēnei "huarahi ngota" i te horapa mō ngā ngota nui ake, ka ārai i te aukati i ngā pūngao, ā, ka whakarei ake i te whai huatanga, inā koa i roto i ngā taiao matotoru, i ngā matū tauhohe matotoru rānei.
Rahi me te Āhua o te Tioata: Ko te whakahaere i te rahi o te matūriki (nano vs. moroiti) me te āhua o waho ka pā ki te roa o te ara horapa, te kiato tākai i roto i ngā tauhohenga, te kaha miihini, me te taunekeneke ki ngā whakaohooho o waho.
Te Whakaahua me te Whakatauira: Ngā Aratohu Matua
Ehara i te mea ngāwari te hanga i ngā tātari ritenga. He mea nui te tautuhi pakari: ka whakaū te X-ray Diffraction (XRD) i te hanganga tioata; ka whakakitea te āhua o te Irahiko (SEM/TEM); ka ine tika te Tātaritanga Whakamomona Hau i te rahi o ngā pore me te horahanga o te mata; ka tirotirohia e te Spectroscopy (IR, NMR) ngā taiao matū me ngā pae hohe. Kei te piki haere te hiranga o te matū rorohiko me te ako mīhini, e tohu ana i ngā tikanga whakamomona, horapa, me te tauhohenga i roto i ngā hanganga mariko, ā, ka tere ake te kimi me te arotau i ngā rauemi hou mā te tātari i ngā huinga raraunga whānui o ngā āhuatanga whakahiato.
Ko tēnei kaha ki te mahi hei kaihoahoa ngota, e hoahoa ana i ngā tātari me te tika o te pokanga mō ngā mahi motuhake, he tohu i tētahi whanaketanga nui. Ka wetekina te pūmanawa mō ngā putanga hou puta noa i ngā mara maha, mai i te kitenga tūpono ki te hoahoa whaitake o ēnei tātari kaha, kāore e kitea.
