China / Japan: Researchers si Kyoto University, na University nke Tokyo na Japan na Jiangsu Nkịtị University dị na China mepụtara a ọhụrụ ihe onwunwe na ike bibiri kpọọ carbon dioxide (CO 2) ụmụ irighiri na tọghata ha n'ime 'bara uru' organic ihe, gụnyere a precursor maka polyurethane. The nnyocha e kọwara na magazin Nature Communications.
The ihe onwunwe bụ a porous nchikota polima (PCP, makwaara dị ka a metal-organic kpuchie), a kpuchie esịnede zinc metal ion. The na-eme nnyocha na-anwale ha ihe onwunwe iji X-ray bughi analysis na chọpụtara na ya nwere ike bibiri weghara naanị CO 2 ụmụ irighiri na ugboro iri ọzọ arụmọrụ karịa ndị ọzọ na PCPs. The ihe onwunwe nwere organic akụrụngwa na a propela-dị ka molekụla Ọdịdị, na dị ka CO 2 irighiri ịgakwuru Ọdịdị, ha bugharia na megharia ikike CO 2 Trapping, dapụtara na nta mgbanwe molekụla ọwa n'ime PCP. Nke a na-enye ohere ọ na-eme ihe dị ka molekụla myọ na ike ịmata ụmụ irighiri site size na udi. The PCP bụkwa recyclable; arụmọrụ nke mkpali emeghị ibelata ọbụna mgbe 10 mmeghachi omume cycles.
Mgbe akada carbon, na converted ihe nwere ike ji mee ka polyurethane, a ihe onwunwe na a dịgasị iche iche nke ngwa gụnyere mkpuchi ihe.
