Masu binciken VCU sun gano wani abu mai tasiri da ke ƙara yawan sinadarin carbon dioxide zuwa formic acid - wani abu da zai iya samar da sabuwar dabarar kama carbon wanda za a iya rage shi yayin da duniya ke fama da sauyin yanayi. Wani abu mai yuwuwar zama muhimmin sinadari ga iskar carbon dioxide.
"An san cewa saurin haɓakar iskar gas mai gurbata muhalli a cikin yanayi da kuma illolin da suke yi wa muhalli na ɗaya daga cikin manyan ƙalubalen da bil'adama ke fuskanta a yau," in ji babban marubucin Dr. Shiv N. Khanna, Farfesa Emeritus na Commonwealth a sashen. physics a Faculty of Humanities VCU. "Mayar da CO2 mai guba zuwa sinadarai masu amfani kamar formic acid (HCOOH) dabara ce mai inganci don rage tasirin CO2. Formic acid ruwa ne mai ƙarancin guba wanda yake da sauƙin jigilarwa da adanawa a yanayin zafi na yanayi. Hakanan ana iya amfani da shi azaman babban abin da ke ƙara sinadarai masu mahimmanci, mai ɗaukar hydrogen a cikin ajiya, da kuma yiwuwar maye gurbin man fetur na gaba."
Hanna da masanin kimiyyar lissafi na VCU Dr. Turbasu Sengupta sun gano cewa tarin chalcogenides na ƙarfe da aka ɗaure na iya zama abubuwan da ke haifar da canjin yanayin zafi na CO2 zuwa formic acid. An bayyana sakamakonsu a cikin wata takarda mai taken "Canza CO2 zuwa Formic Acid ta hanyar Daidaita Yanayin Quantum a cikin Ƙungiyoyin Chalcogenide na Karfe" da aka buga a cikin Fayil ɗin Sadarwa na Kimiyyar Yanayi.
"Mun nuna cewa, tare da haɗin ligands masu dacewa, shingen amsawar da ke hana canza CO2 zuwa formic acid zai iya raguwa sosai, wanda hakan zai hanzarta samar da formic acid," in ji Hanna. "Don haka za mu ce waɗannan abubuwan da ake da'awar suna iya sa haɗa formic acid ya zama mai sauƙi ko kuma ya fi yiwuwa. Amfani da manyan gungu tare da wuraren ɗaure ligand ko ta hanyar haɗa ligands masu inganci ya yi daidai da ƙarin ci gaban da muke samu a canza formic acid fiye da abin da aka nuna a cikin kwaikwayon lissafi."
Binciken ya dogara ne akan aikin da Hanna ta yi a baya wanda ke nuna cewa zaɓin ligand mai kyau na iya mayar da rukuni zuwa superdonor wanda ke ba da gudummawar electrons ko kuma mai karɓa wanda ke karɓar electrons.
"Yanzu mun nuna cewa irin wannan tasirin yana da babban tasiri a cikin catalysis bisa ga ƙungiyar chalcogenide ta ƙarfe," in ji Hanna. "Ikon haɗa ƙungiyoyi masu ƙarfi da kuma sarrafa ikonsu na bayar da gudummawa ko karɓar electrons yana buɗe sabon filin catalysis, tunda yawancin halayen catalytic sun dogara ne akan catalysts waɗanda ke ba da gudummawa ko karɓar electrons."
