KAWANISH, Japan, Nov. 15, 2022 /PRNewswire/ — Makani aabusena mbuli kuchincha kwachiimo chamulengalenga, kumana kwazintu, kumana kwamisyobo yazilenge, kusofwaazyigwa kwamapulasitiki akugonkwa kwamasyokwe akaambo kakuvwula kwabantu munyika zilikuyaabuvwula.
Muya uutegwa carbon dioxide (CO2) muya uusofweede mpawo ngumwi wazintu zipa kuti kube kuchincha kwachiimo chamulengalenga. Muleezi, nzila yiitwa kuti "kupangwa kwamumuni (kugwisya mumumuni wa carbon dioxide)" ilakonzya kupanga zintu zitabelesyegwi zyakupanga mafuta amakemikalu kuzwa ku carbon dioxide, maanzi anguzu zyazuba, mbuli zisyango mbozichita. Aawo awo, zicesya CO2, eeyo iibelesyegwa mbuli zyakulya zyakupanga manguzu amisamu. Aboobo, nzila yakupanga zuba iipangidwe abantu ilizyibidwe kuti ninzila imwi iisumpukide kapati yakukwabilila buumi.
MOFs (zibeela zyabutale-zipona) nzintu zijisi mapopwe mapati zipangidwe atubunga twabutale butakwe buumi alimwi azintu zijatikizya zintu zipona. Zilakonzya kweendelezyegwa aama molecule aali mu nano range aabusena bupati. Akaambo kazyintu eezyi, ma MOF alakonzya kubelesegwa mukubamba muya, kwaandaanya, kuyobola nsimbi, kugwasya, kutola misamu, kusalazya maanzi, zibelesyo zyakumvwa, ma electrode, zisefa, azimwi. Ma MOF akajanwa kuti alakonzya kujata CO2, yalo iikonzya kubelesyegwa kupanga zintu zipona kwiinda mukugwisya CO2 mumuni, alimwi wiitwa kuti artificial photosynthesis.
Ma doti aa quantum, kulubazu lumwi, nzintu ziniini loko (0.5-9 nanometers) zili aamanguzu aakulanga aatobela milawu ya quantum chemistry antoomwe a quantum mechanics. Ziitwa kuti "ma atomu aapangidwe naa ma molecule aapangidwe" nkaambo doti lyomwe lyomwe lilijisi buyo ma atomu naa ma molecule masyoonto kusikila kuzyuulu. Muchiimo eechi, nguzu zyama electron tazichizumanani pe mpawo zilaandaana akaambo kachintu chilibonya chiitwa kuti quantum confinement effect. Muchiimo eechi, bulamfwu bwamumuni uuzwa buyooyeeme abwaamba bwa quantum dot. Aaya ma doti aa quantum alakonzya kubelesegwa mukupanga mumuni akaambo kakukonzya kwawo kuyobola mumuni, alakonzya kupanga ma exciton miingi antoomwe abusena bupati.
Zyoonse zyobile MOFs ama quantum dots zyakabambwa a Green Science Alliance. Chiindi, bakazwidilila kubelesya MOF-quantum dot composites kupanga asidi yafoomu mbuli chintu chigwasya kupanga zuba. Nokuba boobo, aaya ma catalysts ali muchimo cha busi mpawo aaya ma catalyst powder ayelede kuyobolwa kwiinda mukusefa munzila imwi aimwi. Aboobo, nkuyumu kuchibelesya mumakwebo nkaambo nzila eezi tazizumanani pe.
Mukwiingula, ba Kajino Tetsuro, ba Iwabayashi Hirohisa, a Dr. Mori Ryohei baku Green Science Alliance Co., Ltd. bakabelesya minchina yabo kuti bachinche zintu eezyi zipa kuti kube kupanga mumuni uuzwa mujulu aachisani chitaduli mpawo bakajalula busena bupya bwakupanga asidi. Nzila eeyi ilakonzya kuchitwa lyoonse kuti ibelesegwe mumakkampani. Nikwakamana kuchitwa kwakupanga mumuni, maanzi ajisi asidi yafoomu alakonzya kugwisigwa akugwisigwa, mpawo maanzi mapya alakonzya kubikwa muchikombe kuchitila kuti kupanga mumuni kuzumanane.
Asidi yafoomu ilakonzya kunjila mubusena bwamafuta aa haayidirojeni. Chimwi chazintu zipati zipa kuti nyika yoonse itazumizyi mbunga iibelesya haayidirojeni nkakuti haayidirojeni, atomu nsyoonto kwiinda yoonse mububumbo boonse, ilakatazya kubamba, mpawo inga kwadula loko kuyaka busena bwakuyobweda haayidirojeni bujalikidwe kabotu. Mukuyungizya, muya wa haayidirojeni ulakonzya kubboloka mpawo ulakonzya kuleta ntenda. Nchuuba loko kubamba ma formic acid mbuli mafuta nkaambo ngamaanzi. Kuti kakuli kuyandika, asidi yafoomu ilakonzya kuchita kuti kusanduka kuchite kuti kube haayidirojeni. Mukuyungizya, asidi yafoomu ilakonzya kubelesegwa mbuli chintu chakupanga makemikalu aasiyene.
Nikuba kuti bubotu bwakupanga zuba buli munsi loko, mbunga ya Green Science Alliance iyoozumanana kulwana kuti iyungizye bubotu akutalisya nzila yakupanga zuba iibelesyegwa ncobeni.
