KAWANISH, Japan, nindo 15, dwi mir apar wi acel, 2022 /PRNewswire/ — Lembe mi kabedu macalo aloka loka pa kite ma koth ku ceng ryeny kudu, rweny pa piny ma watiyo kudu, rweny pa lei makwiny, dhuny pa plastik man turo yen ma wok kud i rwom ma malu pa dhanu i ng'om zoo ube doko tek.
Carbon dioxide (CO2) ubedo yamu ma nyayu lyethu man acel ikin piny ma nyayu aloka loka pa kite ma koth ku ceng ryeny kudu. I lembe maeni, yore moko ma julwongo ni "artificial photosynthesis (photoreduction of carbon dioxide)" ecopu wodhu piny ma jutiyo kudu pi tiyo ku mac man kemikol kud i carbon dioxide, pii man tego pa ceng, calu ma yen timo. I saa marom, gi dwoko piny CO2 ma juwodho, ma jutiyo kudu calu piny ma jutiyo kudu pi yubu kero man kemikol. Pieno, photosynthesis ma dhanu timo ungeyere ni acel ikin yore maber loyo mi gwoko leng pa piny.
MOFs (metal-organic frameworks) utiye piny ma dongo dongo ma juyubu ku dul pa inorganic metals man organic linkers. Jucopo jwigo gi i rwom pa molecule i nano range ku kabedo malac. Ni lembe eni, MOFs copu tiyo kudu i gwoko gas, poko, mako cuma, catalysis, miyo yath, yiku pii, sensors, electrodes, filters, man mange. MOFs kawoni junwango ni gitiye ku copo mi maku CO2, ma juromo tiyo kudu pi yubu piny ma kwo nikadhu kud i CO2 photoreduction, ma julwongo bende ni artificial photosynthesis.
Quantum dots, ku cing makende, utiye piny ma nok akeca (0.5-9 nanometers) ku kite ma nen kudu ma lubu cik pa quantum chemistry man quantum mechanics. Julwongo gi ni "artificial atoms or artificial molecules" kum quantum dot acel acel utiye ku atoms nyo molecules manok kende. I rwom maeni, kero pa electrons dong epe man edoko tung tung pi lembe moko ma julwongo ni quantum confinement effect. I lembe maeni, bor pa ler ma juwodho bibedo nimakere ku dit pa quantum dot. Quantum dots eni jucopo tiyo kudu i artificial photosynthesis pi kero migi mi mako ler, kero migi mi wodhu exciton madwong man kabedo malac.
MOFs ku quantum dots zo juyubu ku Green Science Alliance. I kare mukadho, gitiyo ku MOF-quantum dot composites maber pi yubu formic acid calu piny ma pire tek pi yubu ler. Ento, catalysts eni gitiye i kit powder man catalysts powders eni umaku jucokiri ku filtration i yore acel acel. Pieno, ebedo tek ni tiyo kudu pi tic mi yiku piny mandha, kum lembe eni gi mediri ngo.
I dwokowang lembe, Mr. Kajino Tetsuro, Mr. Iwabayashi Hirohisa, man Dr. Mori Ryohei pa Green Science Alliance Co., Ltd. gitiyo ku diro migi mi ketho piny ma juyubu ku mac iwi bongo ma wel pare yot man gi yabo kabedo manyen mi yubu acid. Lembe ne copu timere kare ku kare pi tic maber mi tic. I ngei thum pa tic mi yik pa ler, pii ma tye ku formic acid jucopo kwanyu woko man juwodhe, man pii maleng manyen jucopo medu i iye pi mediri ku tic pa ler pa ler.
Formic acid copo loko hydrogen fuel. The lembe acel madit ma nyayu lworo i ng'om zoo ni bedo ku hydrogen utiye nia hydrogen, atom ma nok loyo i wi ngom, tek ni kano, man ecopo bedu tek ni gieru ka gwoko hydrogen maber. Mi medo, yamu ma julwongo ni hydrogen copo bedu piny ma nyai man ecopu bedu rac ni kwo pa dhanu. Ebedo yot ni kano formic acids calu piny ma tiyo ku mac pi en ubedo pii. Ka mitire, formic acid ecopu nyayu aloka loka ni kelo hydrogen in situ. Mi medo, formic acid copo bedu piny ma jutiyo kudu pi kemikol matung tung.
Kadi bende tic pa tic mi yubu ler ma dhanu timo podi piny akeca, Green Science Alliance bimediri ku lwiny pi medo kero man kelo tic maber pa ler ma dhanu timo.
