Ndị nchọpụta VCU achọpụtala ihe na-akpali akpali dị irè maka mgbanwe thermochemical nke carbon dioxide ka ọ bụrụ formic acid - nchọpụta nke nwere ike inye atụmatụ ọhụrụ nke ijide carbon nke enwere ike ibelata ka ụwa na-alụso mgbanwe ihu igwe ọgụ. Ihe nwere ike ịdị mkpa maka carbon dioxide ikuku.
“A maara nke ọma na mmụba ngwa ngwa nke gas griinhaus na ikuku na mmetụta ọjọọ ha na gburugburu ebe obibi bụ otu n'ime ihe ịma aka ndị mmadụ na-eche ihu taa,” ka onye edemede ndu bụ Dr. Shiv N.

"Anyị egosila na, site na njikọta ziri ezi nke ligands, enwere ike ibelata ihe mgbochi mmeghachi omume iji gbanwee CO2 ka ọ bụrụ formic acid nke ukwuu, na-eme ka mmepụta formic acid dị ngwa ngwa," Hanna kwuru. "Ya mere, anyị ga-ekwu na ihe ndị a a na-ekwu na ha nwere ike ime ka mmepụta nke formic acid dịkwuo mfe ma ọ bụ kwe omume karịa.
