Chemical reactions ubetimere i ng'om mwa kare ku kare—nen kamaleng ka iparu pire, ento adi ikindwa ma timo kumeno ka wabe caku mutukari, wabe tedo tong'o, nyo wabe ketho lum i lum mwa?
Jagor mi catalysis pa kemikol Richard Kong ubedu ka paru pi aloka loka pa kemikol. I tic pare calu "jabodho mi wer", calu en gire ewacu, ebedo ku miti ikum adwogi ma wok i iye kende ngo, ento de ikum kelo paru manyen.
Calu Klarman Fellow i Chemistry man Chemical Biology i College of Arts and Sciences, Kong timo tic mi yubu catalysts ma kelo aloka loka mi chemistry ni adwogi ma mitere, ma cwio piny ma ber man ma ber, ikinde piny ma copo bedu ku adwogi maber ikum dhanu. yot kum. Ceng adek.
"Wel madit pa timo pa kemikol timere labongo kony," Kong uwacu, ma eweco ikum wodhu pa carbon dioxide ka mutukari wango piny ma wok kud i ngom. "Ento aloka loka ma tek man ma nyang ikum kemikol timere kende ngo. Kae ma kemikol catalysis bino i iye."
Kong ku juwadi gi goyo piny moko ma copo telo wi lembe ma gimito, man etimere. Ku lapor, carbon dioxide copo doko formic acid, methanol, nyo formaldehyde ku yero catalyst maber man temo ku kite ma timo kudu.
Ni lubre ku Kyle Lancaster, japonji mi chemistry man chemical biology (A&S) man japonji mi Kong, yore pa Kong rwate maber ku yore mi "nwangu" pa Lancaster's lab. "Richard ubedu ku paru mi tiyo ku tin pi medo kero pare, ma ubedu ngo i kyeu para," Lancaster uwacu. "Ebedo piny ma nyayu aloka loka pa carbon dioxide ni piny moko ma pire tek, man carbon dioxide nwangu lembe marac akeca."
Kong ku juwadi gi nwango yore moko ma, i thenge moko, copo loko carbon dioxide ni formic acid.
"Kadi kawoni dong wabecidho ngo i rwom ma malu, yub mwa utiye maber akeca," Kong uwacu. "Kum kumeno wacopo caku ni nyang maber pirango ma catalysts moko timo tic pio pio uloyu mukende, pirango ma catalysts moko ber. Wacopu loko parameters pa catalysts man watemo ni nyang ikum ango ma weko piny eni timo tic pio pio, kum ka gitiyo pio pio, ber - icopo cwio molecules pio pio."
Calu Klarman Fellow, Kong de ubetimo tic mi loko nitrates, piny ma jutiyo kudu ma rwinyo i pii, kud i kabedu ni piny ma rac ungo, ewacu.
Kong utemo ku cuma ma nen calu aluminum man tin calu catalysts. Dhahabu ne gi yot, gipe ku tho man gi dwong in ngom, ci tic kudgi bi kelo ngo peko mi kwo, ewacu.
"Wan bende wabe nyang kudu kite mi yubu catalysts kama ario pa cuma eni gi tiyo karacelu," Kong uwacu. "Ka watiyo ku cuma ario i yub, adwogi ango man penji ma nyangu dhanu ma wacopo nwangu kud i bimetallic systems?" “Adwogi pa kemikol?”
Ni lubre ku Kong, scaffolding ubedo kabedu pa kemikol ma cuma eni bedo i iye.
Pi oro 70 mukadho, cik ubedo ni tiyo ku cuma acel kende pi kelo aloka loka mi kemikol, ento i kind oro apar mukadho, ju ma gisomo lembe mi kemikol gicaku sayu tic pa cuma aryo ma gicokiri nyo ma gicungo karacelu. , Kong uwacu, "Emiyo ibedo agonya madwong."
Bimetallic catalysts eni miyo ju ma timo chemistry kero mi ketho metal catalysts nimakere ku tego man goru migi, Kong uwacu. Ku lapor, dul pa cuma ma mako ngo piny maber ento turo dul maber copo timo tic ku dul mange ma mako piny marac ento mako piny maber. Bedo tiye pa cuma mir aryo de nyayu aloka loka pa cuma mir acel.
"Icopo caku nwangu gin ma walwongo ni synergistic effect ikind dul ario mi cuma," Kong uwacu. "Lembe moko ma ukoc man maber ucaku wok i thenge mi bimetallic catalysis."
Kong uwaco ni podi lembe madwong utiye ma dhanu ungeye ngo ikum kite ma cuma makore kudu ikindgi i ayi pa molecule. Ebedo kud anyonga pi ber pa chemistry ne gire calu ma ebedo kud anyonga pi adwogi ne. Kong jutere i ot yath pa Lancaster pi ngec migi mi X-ray spectroscopy.
"Ebedo dul pa dhanu," Lancaster uwacu. "X-ray spectroscopy ukonyo Richard ni nyang ango ma nwang i the hood man ango ma weko tin ubedo ku kero mi timo lembe eni. Wanwangu bero kud i ngec pare madwong ikum chemistry, ma eyabu yo manyen."
Lembe eca bino piny ikum chemistry man sayusac, yore ma Open Klarman Fellowship uketho ubedo yot, Kong uwacu.
"Pol kare acopo timo tic i ot mi yath nyo bedo i wang kompyuta ka timo tic mi timo lembe," ewacu. "Watemo ni nwangu cal maber pa tic pa kemikol."
