VCU zirchiangtute chuan carbon dioxide chu thermochemical hmanga formic acid-a a chantir theihna tur catalyst tha tak an hmuchhuak a — hei hian khawvelin boruak inthlak danglamna a hmachhawn mek laiin carbon capture strategy thar a pe thei a, hei hi tihtlem theih a ni. Atmospheric carbon dioxide atana thil pawimawh tak ni thei.
“Boruak-a greenhouse gas lo pung chak tak leh boruak tichhe thei lote hi tunlai mihringte hmachhawn tur harsatna lian ber pakhat a ni tih hi hriat lar tak a ni,” tiin lead author Dr. Shiv N. Khanna, Commonwealth Professor Emeritus in the department chuan a sawi. physics chu Faculty of Humanities VCU-ah a zir chhuak a ni. “CO2 chu chemical tangkai tak tak, formic acid (HCOOH)-a catalytic conversion hi CO2-in a nghawng tha lo tihziaawmna atana hmanraw dang man tlawm tak a ni. Formic acid hi toxicity hniam tak liquid a ni a, ambient temperature-a phurh leh dah awlsam a ni a, high value-added chemical precursor, hydrogen storage carrier, leh nakin lawka fossil fuel substitute awm thei atan pawh hman theih a ni bawk.”.
Hanna leh VCU research physicist Dr. Turbasu Sengupta te chuan metal chalcogenides bound clusters te chu CO2 chu formic acid ah thermochemical conversion atan catalyst angin an thawk thei tih an hmuchhuak a. An result hi Communications Chemistry of Nature Portfolio-a tihchhuah, “Metal Chalcogenide Clusters-a Quantum States Tuning hmanga CO2 chu Formic Acid-a chantir” tih paper-ah tarlan a ni.
“Kan lantir tawh a, ligand te hi a dik taka inzawmkhawm chuan CO2 chu formic acid-a chantir theihna tur reaction barrier chu nasa takin a tlahniam thei a, hei hian formic acid siamchhuahna nasa takin a ti chak a ni,” tiin Hanna chuan a sawi. “Chuvangin heng catalyst nia sawite hian formic acid siamna chu a awlsam zawk emaw, a tih theih zawk emaw a siam thei ang kan ti ang. Ligand binding site tam zawk nei cluster lian zawk hman emaw, donor ligand tha zawk attaching hmanga hman emaw hi computational simulations-a kan hmuh aia formic acid conversion lama kan hmasawnna dang kan neih theih dan nen a inmil a ni.”.. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. ..
He zirchianna hian Hanna-i hnathawh hmasa, ligand thlan dik chuan cluster chu electron petu superdonor emaw, electron pawmtu acceptor emaw-ah a chantir thei tih a lantir a ni.
“Tunlai hian chutiang bawk chuan metal chalcogenide clusters hmanga catalysis-ah pawh potential nasa tak a nei tih kan lantir ta a ni,” tiin Hanna chuan a sawi. “Stable bonded clusters siam chhuah theihna leh electron pe thei emaw, pawm emaw theihna control theihna hian catalysis field thar a hawng a, a chhan chu catalytic reaction tam zawk hi electron pe thei emaw, pawm emaw thei catalyst-ah a innghat a ni.”.
Hemi kawngah hian experimental scientist hmasa ber zinga mi, Columbia University-a Associate Professor of Chemistry Dr. Xavier Roy chuan April 7 hian VCU a tlawh dawn a, Physics Department Spring Symposium neih a ni ang.
“A experimental lab hmanga catalyst ang chi hi engtin nge kan siam chhuah theih ang leh kan kalpui theih ang tih kan ngaihtuah dawn a ni,” tiin Hanna chuan a sawi. “A group nen hian kan thawk dun tawh a, magnetic material chi thar an siam chhuak a, tun ṭumah hian catalyst a ni dawn a ni.”
