Imboni yamakhemikhali namuhla idinga izinqubo zezinhlanganisela eziyinkimbinkimbi ze-organic, ukukhiqizwa okubiza kakhulu, ngoba kususelwa ekuphendukeni kwendabuko kwendabuko (indlela ebaluleke kakhulu yokwakha ububele be-carbon), futhi kuholele ekwakhekeni kwenani elikhulu le imfucuza. Indlela ehlukile futhi ethembisayo ukuguqula ukuphendula lapho amanzi asebenza khona njengoMkhiqizo.
"Umqondo wesifundo sethu ukusebenzisa uhlobo olukhethekile lwe-catalyst lapho ingxenye esebenzayo, i-palladium isesimweni sezikhungo ze-monatomic eziqhelile ezivalelwe izinto zokwakha ama-nanoporous - amaZeolites.
Kuyavela ukuthi ukusabela kuqhubeka ngaphakathi kwama-pores, amafomu athile nosayizi, kanye nemikhiqizo engaphendulwanga yenziwa "ukuvumelanisa" nale pharamitha. Umqondo obubonakala ulula, kepha ngaphambi kokuba kungabikho muntu okwazile ukukubona, "kusho omunye wababhali bocwaningo, inhloko ye-nanodiagnostic elebhu yaseSouthern Federal University, e-Aram Bugaev.
Kusetshenziswa isibonelo sokusabela okubophayo kweTolune, ososayensi bathola ukuthi ukuhanjiswa kwemikhiqizo kushintshwa kakhulu ekwethulweni kwezikhungo zePalladium ezisebenzayo kuma-zeolites anosayizi ohlukile kanye nefomu lama-pores. Isakhiwo esinembile sezikhungo zePalladium ezisebenzayo sasungulwa ngesisekelo sezilinganiso ze-Synchrotron ze-X-ray Absorption Spectra nokuhlaziywa kwazo nge-copyright, ngokusekelwe kuma-algorithms wokufunda ngomshini.
"Lesi yisibonelo esihle kakhulu sokuthi izindlela ezisethuthukile zokuhlanganiswa kwamakhemikhali zihlangana nokuxilongwa kwezitshalo zaseMegasaine kanye ne-supercomputer yanamuhla ye-supercolologies evumela ukuthi ufinyelele imiphumela esebenza kahle nesezingeni eliphakeme.
Ucwaningo lwethu lunikezelwe hhayi ku-catalyst entsha ye-heterogeneous, inikeza umqondo wokuguqula amandla okulawula ukusabalala kwesicelo esisebenzayo embonini, "kuphawula ngemiphumela yoMqondisi Wokufunda we-International Research Institute of Intellial Materials South Africa, inhloko yeRussia Iphrojekthi -Belgian, uSolwazi Alexander Aldatov.
Izinto ezintsha, i-catalyst, zenza ukuthi zikwazi ukukhiqiza izinto ezibalulekile zesakhiwo se-organic synthesis - ama-biarlines, asetshenziswa kabanzi kwizimboni zanamuhla zamakhemikhali namakhemikhali. Isidingo esikhulayo se-Biarlines embonini ye-polymer kungenxa yokuqina kwawo okukhulu nokuvikeleka kwabantu kanye nemvelo. Ukwethulwa kwezinto ezihlongozwayo ekukhiqizweni kwe-Biarlov kuzonciphisa kakhulu izindleko zale nqubo nokwandisa ubukhulu bawo. Ucwaningo lwenziwe ngohlaka lwephrojekthi ehlanganyelwe yaseRussia-Belgian futhi yashicilelwa ku-The Natual Catalysis Magazine.
