Kumagazini wakamuva wephephabhuku elithi "Journal of the American Chemical Society," iqembu locwaningo likaSolwazi uDkt. Johannes Teichert (TU Chemnitz, Organic Chemistry), kanye nabalingani bocwaningo beqembu elisebenzayo likaSolwazi uDkt. Fabian Dielmann (University of Innsbruck, Inorganic Chemistry), lethula imiphumela yocwaningo ku-catalyst entsha yethusi, esebenza kabili. I-molecule entsha, esekelwe ethusi, esebenza kabili iqukethe amayunithi amabili kanye... Funda kabanzi »

Ithimba le-JGU lisungule ama-catalyst angabizi futhi asebenzayo okuhlukaniswa kwamanzi ukuze kukhiqizwe i-hydrogen eluhlaza, okusebenza kwawo kukhula ngokumangalisayo ngokuhamba kwesikhathi. I-Hydrogen iyindlela okuxoxwa ngayo kakhulu endleleni eya ekukhiqizweni kwamandla angathathi hlangothi kwe-CO₂. Ugesi ovela emithonjeni evuselelekayo - ikakhulukazi amandla omoya kanye nelanga - usetshenziswa kuma-electrolyzer ukuhlukanisa amanzi abe izingxenye zawo i-oxygen kanye ne-hydrogen egcinwayo...

I-hydrogen, njengendlela ehlukile engenawo ugesi esikhundleni samafutha angaphansi komhlaba, iyaqhubeka nokuba umshayeli oyinhloko wekusasa elihlanzekile neliqhubekayo. Nakuba ukukhiqizwa kwe-hydrogen enkulu kuthembisa, kudinga ama-catalyst abizayo asekelwe eplatinum. Ukuze babhekane nale nselele, abacwaningi baseTokyo University of Science (TUS) bathuthukise i-catalyst entsha yokuthuthukiswa kwe-hydrogen besebenzisa ama-nanosheet e-palladium (PdDI) afinyelela ukusebenza kahle okufana ne-platinum...

Eqoqweni elincane le-manganese oxide, amaqembu avela eHelmholtz Centre Berlin (HZB) kanye naseHumboldt University of Berlin athole inhlanganisela ethokozisayo kakhulu: izikhungo ezimbili ze-manganese ezinezimo ezimbili ezihlukene kakhulu ze-oxidation kanye ne-high spin. Le nhlanganisela iyimodeli elula kakhulu ye-catalyst, eyenzeka futhi ku-photosynthesis yemvelo, lapho ivumela ukwakheka kwe-oxygen yamangqamuzana. Funda kabanzi »
