Amashanyarazi ya molekulari - ibikoresho bya kristalline bifite imyenge imwe, ingero zingana na molekile - ni amahame y'ibanze mu nganda zigezweho, bituma habaho gutandukana gukomeye, kwezwa, hamwe na catalitiki. Mugihe gakondo ya "off-the-shelf" ikora neza, impinduka ihinduka iraba: izamuka rya molekulari yihariye. Iyi paradigima irenga ibirenze ibintu bifatika biganisha ku bushake, bwububiko bwububiko bwa chimie na chimie kugirango bikemure ibibazo byihariye, bigoye ibisubizo rusange bidashobora gukemura.
Kuki Customisation? Imbaraga zo gutwara
Inganda zirimo gusunika imipaka, zisaba ubuziranenge butigeze bubaho, gukora neza mu buryo bukoresha ingufu, inzira nshya y’imiti, hamwe n’ibisubizo by’ibibazo bikomeye by’ibidukikije. Amashanyarazi asanzwe, akenshi agarukira kubunini bwa pore ihamye, imiterere yimiti, cyangwa kwandura nabi, kugwa bigufi. Gukoresha adresse ikenera nko gutandukanya molekile zisa-imwe (urugero, isomeri yihariye ya xylene), itanga ibisubizo byatoranijwe cyane hamwe n imyanda mike, gutunganya ibiryo byangiritse cyangwa byanduye, hamwe no kuzuza ibyifuzo byihariye bya porogaramu zigaragara nko gufata karubone cyangwa kweza hydrogene.
Ibikoresho bya Molecular Architecture: Ubudozi
Gukora icyuma cya molekulari ya bespoke nigikorwa gikomeye cyibikoresho siyanse na chimie, birimo gukoresha neza ibintu byinshi byingenzi:
Ingano nini & Geometrie: Igikorwa cyibanze. Ubuhanga bwa Synthesis ubu butuma igenzurwa ritigeze ribaho kuri pore diameter (sub-nanometero kugeza ku gipimo cya nanometero) n'imiterere (imiyoboro, akazu). Ibi byerekana neza molekile zishobora kwinjira, gukwirakwiza, no gukorana, bigafasha gutandukanya imvange zabanje gutandukana cyangwa imiterere-ihitamo catalizike.
Ibigize Framework: Kwimuka kurenga aluminosilicates ya kera (zeolite), ikubiyemo ibintu nka titanium, amabati, germanium, cyangwa fosifori (kurema aluminofosifate - AlPOs, cyangwa silicoaluminophosphates - SAPOs) ihindura cyane imyitwarire yimiti. Ihuza ubwoko (Brønsted / Lewis) n'imbaraga za acide / shingiro, ingenzi kubikorwa bya catalitiki no guhitamo.
Ubutaka bwa Chimie & Imikorere: Guhindura ibice byimbere yimbere nyuma ya synthesis (“grafting”) cyangwa mugihe cya synthesis itangiza amatsinda yihariye kama, inganda zicyuma, cyangwa nanoparticles. Ibi byongeramo imbuga za catalitiki, ihindura adsorption ifitanye isano (urugero, gukora isura hydrophobique), cyangwa igafasha ibikorwa bishya nko gutandukanya chiral.
Inzira ya Hierarchical: Guhuza microporosity isanzwe (pore nto) hamwe na meso- cyangwa macropores yatangijwe nkana ikora umuyoboro wo gutwara abantu benshi. Uyu "nzira nyabagendwa" itezimbere cyane ikwirakwizwa rya molekile nini, irinda guhagarika imyenge, kandi ikongera imikorere, cyane cyane mubidukikije cyangwa ibinyabuzima byinshi.
Ingano ya Crystal & Morphology: Kugenzura ingano yubunini (nano na micro) hamwe nuburyo bwo hanze bigira ingaruka kumurambararo wogukwirakwiza, gupakira ubwinshi mumashanyarazi, imbaraga za mashini, no gukorana nibitera imbaraga.
Ibiranga & Icyitegererezo: Ibyingenzi byingenzi
Gushushanya amashanyarazi yihariye ntabwo ari ugukeka. Ibiranga imbaraga nibyingenzi: X-ray Itandukaniro (XRD) yemeza imiterere ya kristu; Electron Microscopy (SEM / TEM) igaragaza morphologie; Isesengura rya gaz Adsorption Isesengura neza neza ubunini bwa pore nubuso bwubuso; Spectroscopy (IR, NMR) isuzuma ibidukikije nibidukikije. Ubuhanga bwo kubara hamwe no kwiga imashini nibyingenzi cyane, guhanura adsorption, gukwirakwizwa, hamwe nuburyo bwo kubyitwaramo muburyo bwimikorere no kwihutisha kuvumbura no gutezimbere ibikoresho bishya ukoresheje isesengura ryinshi ryimibare-yumutungo.
Ubu bushobozi bwo gukora nkabubatsi ba molekuline, gushushanya sikeri hamwe no kubaga neza kubikorwa byihariye, birerekana iterambere ryimbitse. Ifungura ubushobozi bwo gutera imbere mumirima myinshi, ikava mubuvumbuzi bwa serendipitous igana ku gishushanyo mbonera cyimbaraga zikomeye, zitagaragara muyunguruzi.
