Wata ƙungiyar bincike ta ƙasar Jamus ta ƙirƙiro manyan kristal masu girma biyu masu siffar bimetallic tare da kyawawan halaye na catalytic. Ana iya amfani da su don samar da hydrogen ta hanyar rusa formic acid, tare da samun sakamako mai kyau.
Masana kimiyya karkashin jagorancin Jami'ar Ludwig Maximilian ta Munich (LMU Munich) da ke Jamus sun ƙirƙiro fasahar photocatalytic don samar da hydrogen bisa ga plasma bimetallic supercrystals masu girma biyu.
Masu binciken sun tattara tsarin plasmonic ta hanyar haɗa nau'ikan nanoparticles na zinariya guda ɗaya (AuNPs) da nanoparticles na platinum (PtNPs).
Mai bincike Emiliano Cortes ya ce: "Shirye-shiryen ƙwayoyin zinare yana da matuƙar tasiri wajen mayar da hankali kan hasken da ke faruwa da kuma samar da filayen lantarki masu ƙarfi na gida, waɗanda ake kira wuraren zafi, waɗanda ke samuwa tsakanin ƙwayoyin zinare."
A cikin tsarin da aka tsara, hasken da ake iya gani yana hulɗa sosai da electrons ɗin da ke cikin ƙarfe kuma yana sa su yi rawar jiki da ƙarfi, wanda ke sa electrons ɗin su yi tafiya tare da sauri daga gefe ɗaya na nanoparticle zuwa ɗayan. Wannan yana ƙirƙirar ƙaramin maganadisu wanda ƙwararru ke kira lokacin dipole.
Sakamakon girman cajin ne da kuma nisan da ke tsakanin cibiyoyin caji mai kyau da mara kyau. Lokacin da wannan ya faru, ƙwayoyin nano suna ɗaukar ƙarin hasken rana kuma suna mayar da shi zuwa electrons masu ƙarfi sosai. Suna taimakawa wajen sarrafa halayen sinadarai.
Al'ummar ilimi ta gwada ingancin sinadarin plasmonic bimetallic 2D supercrystals wajen lalata formic acid.
"An zaɓi hanyar binciken ne saboda zinare ba ta da tasiri fiye da platinum kuma saboda ita ce mai ɗaukar H2 mai hana carbon," in ji su.
"Ingantaccen aikin platinum da aka yi a gwajin haske ya nuna cewa hulɗar hasken da ya faru da jerin gwal yana haifar da samuwar platinum a ƙarƙashin ƙarfin lantarki," in ji su. "Hakika, lokacin da ake amfani da formic acid a matsayin mai ɗaukar H2, AuPt supercrystals sun bayyana suna da mafi kyawun aikin plasma."
Gilashin ya nuna yawan samar da H2 na 139 mmol a kowace gram na mai kara kuzari a kowace awa. Ƙungiyar binciken ta ce wannan yana nufin cewa kayan photocatalytic yanzu suna riƙe da tarihin duniya na samar da hydrogen ta hanyar cire sinadarin formic acid a ƙarƙashin tasirin haske da hasken rana.
Masana kimiyya sun gabatar da sabuwar mafita a cikin takarda mai taken "Plasmonic bimetallic 2D supercrystals don samar da hydrogen," wacce aka buga kwanan nan a cikin mujallar Nature Catalice. Tawagar ta haɗa da masu bincike daga Jami'ar Free ta Berlin, Jami'ar Hamburg da Jami'ar Potsdam.
"Ta hanyar haɗa ƙwayoyin plasma da ƙarfe masu ƙarfafawa, muna haɓaka haɓaka masu ƙarfafawa don aikace-aikacen masana'antu. Wannan sabuwar hanya ce ta amfani da hasken rana kuma tana da yuwuwar wasu halayen, kamar canza carbon dioxide zuwa abubuwa masu amfani," in ji Cole Thes.
