Ngā mihi nui ki a koe mō tō toro mai ki Nature.com. He iti noa te tautoko CSS mō te putanga o te pūtirotiro e whakamahia ana e koe. Mō ngā hua pai rawa atu, ka tūtohu mātou kia whakamahia he putanga hou ake o tō pūtirotiro (kia whakawetohia rānei te aratau hototahi i roto i te Internet Explorer). I tēnei wā, hei whakarite i te tautoko tonu, kei te whakaatu mātou i te pae me te kore he momo kāhua, he JavaScript rānei.
Ināianei, i roto i te tuhinga Joule, ka pūrongo a Ung Lee mā i tētahi rangahau mō tētahi tipu whakamātautau mō te whakahāngai i te hauhā waro hei whakaputa waikawa formic (K. Kim et al., Joule https://doi.org/10.1016/j. Joule.2024.01). 003;2024). E whakaatu ana tēnei rangahau i te arotautanga o ētahi wāhanga matua o te tukanga hanga. I te taumata tauhohenga, mā te whakaaro ki ngā āhuatanga matua o te whakakōkī pēnei i te pai o te whakakōkī, te āhua, te wairewatanga wai, te pumau wera, me te wātea o ngā rauemi nui ka āwhina i te whakapai ake i te mahi a te tauhohenga me te pupuri i ngā rahinga kai e hiahiatia ana kia iti. I konei, i whakamahia e ngā kaituhi he whakakōkī ruthenium (Ru) i tautokona i runga i tētahi anga triazine bipyridyl-terephthalonitrile covalent whakauru (e kiia nei ko Ru/bpyTNCTF). I arotauhia e rātou te kōwhiringa o ngā takirua amine e tika ana mō te hopu me te hurihanga CO2 whai hua, me te whiriwhiri i te N-methylpyrrolidine (NMPI) hei amine tauhohe hei hopu i te CO2 me te whakatairanga i te tauhohenga hauwai hei hanga formate, me te N-butyl-N-imidazole (NBIM) hei amine tauhohe. I muri i te wehea o te amine, ka taea te wehe i te formate mō te whakaputanga atu o te FA mā te hanganga o te trans-adduct. Hei tāpiri, i whakapai ake rātou i ngā āhuatanga whakahaere o te tauhohenga e pā ana ki te pāmahana, te pēhanga me te ōwehenga H2/CO2 hei whakanui ake i te hurihanga CO2. Mō te hoahoa tukanga, i whakawhanakehia e rātou he taputapu kei roto ko te tauhohenga moenga maturuturu me ngā pou whakatōtō tonu e toru. Ka whakatōtōhia te paikāponate toenga i te pou tuatahi; ka whakaritea te NBIM mā te hanga i te trans adduct i te pou tuarua; ka whiwhihia te hua FA i te pou tuatoru; I āta whakaarohia hoki te kōwhiringa o ngā rauemi mō te tauhohenga me te pourewa, me te whiriwhiri i te kowiri tira (SUS316L) mō te nuinga o ngā wāhanga, me te whiriwhiri i tētahi rauemi zirconium arumoni (Zr702) mō te pourewa tuatoru hei whakaiti i te waikura o te tauhohenga nā tōna ātete ki te waikura o te huihuinga wahie, ā, he iti noa te utu.
I muri i te arotautanga āta i te tukanga whakaputa—te whiriwhiri i te rauemi kai tino pai, te hoahoa i tētahi tauhohenga moenga maturuturu me ngā pou whakatōtika tonu e toru, te whiriwhiri āta i ngā rauemi mō te tinana pou me te tākai ā-roto hei whakaiti i te waikura, me te whakatikatika i ngā āhuatanga whakahaere o te tauhohenga—e whakaatu ana ngā kaituhi kua hangaia he tipu whakamātautau me te kaha ia rā o te 10 kg o te huihuinga wahie ka taea te pupuri i te mahi pumau mō te neke atu i te 100 hāora. Mā te tātaritanga āta mahi me te huringa ora, i whakaitihia e te tipu whakamātautau ngā utu mā te 37% me te kaha whakamahana ā-ao mā te 42% ki te whakataurite ki ngā tukanga whakaputa huihuinga wahie tuku iho. Hei tāpiri, ko te whai huatanga whānui o te tukanga ka eke ki te 21%, ā, he rite te whai huatanga o te pūngao ki te whai huatanga o ngā waka pūtau wahie e whakamahia ana e te hauwai.
