Ua ʻike nā kānaka noiʻi VCU i kahi mea hoʻoulu kūpono no ka hoʻololi thermochemical o ke kalapona ʻokikene i ka waikawa formic - kahi ʻike e hiki ke hāʻawi i kahi hoʻolālā hopu kalapona hou e hiki ke hoʻemi ʻia i ka wā e hakakā nei ka honua me ka loli o ke aniau. He mea nui paha no ke kalapona ʻokikene lewa.
"Ua ʻike maopopo ʻia ʻo ka ulu wikiwiki ʻana o nā kinoea ʻōmaʻomaʻo i ka lewa a me ko lākou hopena maikaʻi ʻole i ke kaiapuni kekahi o nā pilikia nui e kū nei i ke kanaka i kēia lā," wahi a ke alakaʻi kākau ʻo Kauka Shiv N. Khanna, Polopeka Emeritus o ke Aupuni Hui Pū ʻIa ma ke keʻena. physics ma ke Kulanui o nā Humanities VCU. "ʻO ka hoʻololi catalytic o CO2 i nā kemika pono e like me ka waikawa formic (HCOOH) he hoʻolālā ʻē aʻe e uku pono ai e hōʻemi i nā hopena maikaʻi ʻole o CO2. ʻO ka waikawa formic kahi wai haʻahaʻa ka ʻawaʻawa i maʻalahi ke lawe a mālama i ka mahana ambient. Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻomākaukau kemika waiwai nui, mea lawe mālama hydrogen, a me kahi pani wahie fossil e hiki mai ana."
Ua ʻike ʻo Hanna lāua ʻo Kauka Turbasu Sengupta, he loea noiʻi VCU, hiki i nā hui chalcogenides metala ke hana ma ke ʻano he mau mea hoʻoulu no ka hoʻololi thermochemical o CO2 i ka waikawa formic. Ua wehewehe ʻia kā lākou mau hopena ma kahi pepa i kapa ʻia ʻo "Conversion of CO2 to Formic Acid by Tuning Quantum States in Metal Chalcogenide Clusters" i paʻi ʻia ma Communications Chemistry of Nature Portfolio.
"Ua hōʻike mākou, me ka hui kūpono o nā ligands, hiki ke hoʻohaʻahaʻa nui ʻia ka pale ʻana i ka hoʻololi ʻana i ka CO2 i ka waikawa formic, e wikiwiki nui ana i ka hana ʻana o ka waikawa formic," wahi a Hanna. "No laila e ʻōlelo mākou e hiki i kēia mau mea hoʻouluulu i koi ʻia ke maʻalahi a ʻoi aku ka hiki ke hana i ka synthesis o ka waikawa formic. ʻO ka hoʻohana ʻana i nā hui nui me nā wahi hoʻopaʻa ligand hou aʻe a i ʻole ma ka hoʻopili ʻana i nā ligands donor ʻoi aku ka maikaʻi e kūlike me kā mākou hoʻomaikaʻi hou ʻana i ka hoʻololi ʻana o ka waikawa formic hiki ke hoʻokō ʻia ma luna o ka mea i hōʻike ʻia ma nā simulations computational."
Kūkulu ʻia ke aʻo ʻana ma ka hana mua a Hanna e hōʻike ana e hiki i ke koho kūpono o ka ligand ke hoʻololi i kahi hui i loko o kahi superdonor e hāʻawi ana i nā electrons a i ʻole kahi mea ʻae e ʻae ana i nā electrons.
"I kēia manawa ke hōʻike nei mākou he nui ka hopena like i ka catalysis e pili ana i nā hui chalcogenide metala," wahi a Hanna. "ʻO ka hiki ke synthesize i nā hui paʻa i hoʻopaʻa ʻia a kāohi i ko lākou hiki ke hāʻawi a ʻae paha i nā electrons e wehe i kahi kahua hou o ka catalysis, ʻoiai ʻo ka hapa nui o nā hopena catalytic e hilinaʻi nei i nā catalysts e hāʻawi a ʻae paha i nā electrons."
ʻO kekahi o nā kānaka ʻepekema hoʻokolohua mua loa ma ke kahua, ʻo Kauka Xavier Roy, Polopeka Hoa o ke Kemika ma ke Kulanui ʻo Columbia, e kipa aku iā VCU ma ka lā 7 ʻApelila no ka Physics Department Spring Symposium.
"E hana pū ana mākou me ia e ʻike pehea e hiki ai iā mākou ke hoʻomohala a hoʻokō i kahi mea hoʻoulu like me ka hoʻohana ʻana i kāna keʻena hoʻokolohua," wahi a Hanna. "Ua hana pū mākou me kāna hui, kahi i hana ai lākou i kahi ʻano mea magnetic hou. I kēia manawa, ʻo ia ke mea hoʻoulu."
