KAWANISH, Iapana, Nowemapa 15, 2022 /PRNewswire/ — Ke lilo nei nā pilikia kaiapuni e like me ka loli o ke aniau, ka hoʻopau ʻana i nā kumuwaiwai, ka pau ʻana o nā ʻano holoholona, ​​ka haumia plastik a me ka luku ʻāina i hoʻokumu ʻia e ka piʻi ʻana o ka heluna kanaka o ka honua i mea koʻikoʻi.
He kinoea ʻōmaʻomaʻo ka carbon dioxide (CO2) a ʻo ia kekahi o nā kumu nui o ka loli o ke aniau. Ma kēia ʻano, hiki i kahi hana i kapa ʻia ʻo "artificial photosynthesis (photoreduction of carbon dioxide)" ke hana i nā mea maka organik no ka wahie a me nā kemika mai ke kalapona dioxide, ka wai a me ka ikehu o ka lā, e like me ka hana a nā mea kanu. I ka manawa like, hoʻemi lākou i nā hoʻokuʻu CO2, i hoʻohana ʻia ma ke ʻano he feedstock no ka ikehu a me ka hana kemika. No laila, ua ʻike ʻia ka photosynthesis artificial ʻo ia kekahi o nā ʻenehana ʻōmaʻomaʻo holomua loa.
ʻO nā MOF (metal-organic frameworks) he mau mea superporous i haku ʻia me nā hui o nā metala inorganic a me nā mea hoʻopili organik. Hiki ke hoʻomalu ʻia lākou ma ka pae molekala ma ka pae nano me kahi ʻili nui. Ma muli o kēia mau waiwai, hiki ke hoʻohana ʻia nā MOF i ka mālama ʻana i ke kinoea, ka hoʻokaʻawale ʻana, ka adsorption metala, ka catalysis, ka lawe ʻana i nā lāʻau lapaʻau, ka mālama ʻana i ka wai, nā sensor, nā electrodes, nā kānana, a me nā mea ʻē aʻe. Ua ʻike ʻia i kēia manawa he hiki i nā MOF ke hopu i ka CO2, hiki ke hoʻohana ʻia e hana i nā mea organik ma o ka CO2 photoreduction, i ʻike ʻia hoʻi ʻo ka photosynthesis artificial.
ʻO nā kiko Quantum, ma ka ʻaoʻao ʻē aʻe, he mau mea liʻiliʻi loa (0.5-9 nanometers) me nā waiwai optical e mālama ana i nā lula o ke kemika quantum a me ka mechanics quantum. Ua kapa ʻia lākou he "nā ʻātoma hana a i ʻole nā ​​​​mole hana" no ka mea ʻo kēlā me kēia kiko quantum he kakaikahi wale nō a i ʻole nā ​​​​​​kaukani o nā ʻātoma a i ʻole nā ​​​​​​mole. Ma kēia pae nui, ʻaʻole e hoʻomau hou nā pae ikehu o nā electrons a lilo i hoʻokaʻawale ʻia ma muli o kahi hanana kino i ʻike ʻia ʻo ka hopena quantum confinement. I kēia hihia, e hilinaʻi ka nalu o ke kukui i hoʻopuka ʻia ma ka nui o ke kiko quantum. Hiki ke hoʻopili ʻia kēia mau kiko quantum i ka photosynthesis hana ma muli o ko lākou hiki ke hoʻomoʻa i ka mālamalama kiʻekiʻe, hiki ke hoʻoulu i nā exciton he nui a me ka ʻili nui.
Ua hoʻohui ʻia nā MOF a me nā kiko quantum e ka Green Science Alliance. Ma mua, ua hoʻohana pono lākou i nā MOF-quantum dot composites e hana i ka waikawa formic ma ke ʻano he mea hoʻoulu kūikawā no ka photosynthesis artificial. Eia nō naʻe, aia kēia mau mea hoʻoulu i ke ʻano pauka a pono e hōʻiliʻili ʻia kēia mau pauka hoʻoulu ma o ka kānana ʻana i kēlā me kēia kaʻina hana. No laila, he paʻakikī ke hoʻopili iā ia i ka hoʻohana ʻoihana maoli no ka mea ʻaʻole hoʻomau kēia mau kaʻina hana.
I ka pane ʻana, ua hoʻohana ʻo Mr. Kajino Tetsuro, ʻo Mr. Iwabayashi Hirohisa, a me Kauka Mori Ryohei o Green Science Alliance Co., Ltd. i kā lākou ʻenehana e hoʻopaʻa i kēia mau mea hoʻoulu photosynthesis hana kūikawā ma kahi lole lole makepono a wehe i kahi hale hana waikawa formic hou. Hiki ke holo mau ke kaʻina hana no nā noi ʻoihana kūpono. Ma hope o ka pau ʻana o ka hopena photosynthesis hana, hiki ke lawe ʻia a unuhi ʻia ka wai i loaʻa ka waikawa formic, a laila hiki ke hoʻohui ʻia ka wai hou i loko o ka ipu e hoʻomau i ka hoʻomaka hou ʻana o ka photosynthesis hana.
Hiki i ka waikawa formic ke pani i ka wahie hydrogen. ʻO kekahi o nā kumu nui e kāohi ana i ka hoʻohana ʻana o ka honua holoʻokoʻa i kahi kaiāulu e pili ana i ka hydrogen, ʻo ia ka paʻakikī o ka mālama ʻana i ka hydrogen, ka ʻātoma liʻiliʻi loa o ke ao holoʻokoʻa, a he pipiʻi loa ke kūkulu ʻana i kahi waihona hydrogen i hoʻopaʻa pono ʻia. Eia kekahi, hiki i ke kinoea hydrogen ke pahū a hoʻoweliweli i ka palekana. He mea maʻalahi loa ka mālama ʻana i nā waikawa formic ma ke ʻano he wahie no ka mea he wai lākou. Inā pono, hiki i ka waikawa formic ke hoʻoulu i ka hopena e hana i ka hydrogen ma kahi. Eia kekahi, hiki ke hoʻohana ʻia ka waikawa formic ma ke ʻano he mea maka no nā kemika like ʻole.
ʻOiai inā haʻahaʻa loa ka pono o ka photosynthesis artificial i kēia manawa, e hoʻomau ka Green Science Alliance i ka hakakā e hoʻonui i ka pono a hoʻolauna i ka photosynthesis artificial i hoʻopili maoli ʻia.
