Vaongorori veVCU vakawana chinhu chinoshanda pakushandura kabhoni dhayokisaidhi kuita formic acid mukupisa kwemuviri — kuwanikwa kunogona kupa nzira itsva yekubata kabhoni inogona kuderedzwa sezvo nyika iri kurwisana nekushanduka kwemamiriro ekunze. Chinhu chinogona kunge chakakosha mumhepo ine kabhoni dhayokisaidhi.
"Zvinozivikanwa kuti kukura nekukurumidza kwemagasi ekupisa mumhepo uye kukanganisa kwawo zvakatipoteredza ndeimwe yematambudziko makuru ari kusangana nevanhu nhasi," akadaro munyori mukuru Dr. Shiv N. Khanna, Purofesa weCommonwealth Emeritus mudhipatimendi refizikisi paFaculty of Humanities VCU. "Kuchinja kweCO2 kuita makemikari anobatsira akadai seformic acid (HCOOH) inzira inodhura zvishoma yekuderedza migumisiro yakaipa yeCO2. Formic acid imvura ine chepfu shoma iri nyore kutakura nekuchengeta pakupisa kwekunze. Inogona zvakare kushandiswa semushonga wemakemikari anowedzera kukosha, hydrogen storage carrier, uye inogona kushandiswa mune ramangwana sechinotsiva mafuta efossil."
Hanna nachiremba wefizikisi weVCU Dr. Turbasu Sengupta vakawana kuti mapoka esimbi akabatana anogona kushanda sema catalysts ekushandura CO2 kuita formic acid mu thermochemical. Mhedzisiro yavo inotsanangurwa mupepa rine musoro unoti "Kushandurwa kweCO2 kuita Formic Acid neTuning Quantum States muMetal Chalcogenide Clusters" rakaburitswa muCommunications Chemistry of Nature Portfolio.
"Taratidza kuti, nekusanganiswa kwakakodzera kwema ligands, chipingamupinyi chekuchinja CO2 kuita formic acid chinogona kudzikiswa zvakanyanya, zvichikurumidzisa kugadzirwa kwe formic acid," akadaro Hanna. "Saka tingati ma catalysts aya anonzi anogona kuita kuti kugadzirwa kwe formic acid kuve nyore kana kuti kuve nyore. Kushandiswa kwema clusters makuru ane nzvimbo dzakawanda dze ligand dzinosunga kana nekubatanidza ma donor ligands anoshanda zviri pamutemo nekuvandudzwa kwedu mukushandurwa kwe formic acid kunogona kuitwa pane zvinoratidzwa mu computational simulations."
Chidzidzo ichi chinovakira pane zvakamboitwa naHanna zvichiratidza kuti sarudzo chaiyo ye ligand inogona kushandura boka kuita superdonor inopa maerekitironi kana acceptor inogamuchira maerekitironi.
"Zvino tava kuratidza kuti mhedzisiro imwe chete iyi ine mukana mukuru mukugadzira ma "catalysis" zvichibva pa "metal chalcogenide clusters," anodaro Hanna. "Kugona kugadzira ma "stable bonded clusters" uye kudzora kugona kwavo kupa kana kugamuchira ma "electrons" kunovhura nzvimbo itsva ye "catalysis", sezvo maitiro mazhinji e "catalytic reactions" achitsamira pama "catalysts" anopa kana kugamuchira ma "electrons."
Mumwe wevasayendisiti vekutanga vekuedza mumunda uyu, Dr. Xavier Roy, Mubatsiri wePurofesa weChemistry paColumbia University, achashanyira VCU musi wa7 Kubvumbi kuFizikisi yeChirimo yeSymposium.
"Tichashanda naye kuti tione kuti tingagadzira sei uye tishandise catalyst yakafanana tichishandisa lab yake yekuedza," akadaro Hanna. "Tatoshanda pamwe chete neboka rake, kwavakagadzira mhando itsva yezvinhu zvine magineti. Panguva ino ndiye achava catalyst."
