Brazil ndiyo inogadzira pasi rose niobium uye inobata zvikamu makumi mapfumbamwe nesere kubva muzana zvezvakachengetwa zviri pasi pano. Ichi chemakemikari chinhu chinoshandiswa musimbi alloys, kunyanya-yakasimba-simbi, uye mune inenge isingaperi dhizaini yemhando yepamusoro-tekinoroji yekushandisa kubva kunharembozha kuenda kune injini dzendege. Brazil inotumira kunze yakawanda yeniobium yainogadzira nenzira yezvinhu zvakadai seferronobium.

Chimwe chinhu cheBrazil chinewo zvakawanda asi chisisashandiswe iglycerol, inogadzirwa neoiri nemafuta saponification muindasitiri yesipo uye yekugezesa, uye yekuchinja kwekuchinja muindasitiri yebiodiesel. Muchiitiko ichi mamiriro acho akanyanya kuipa nokuti glycerol inowanzoraswa semarara, uye kuraswa kwakakodzera kwemavhoriyamu makuru kwakaoma.

Ongororo yakaitwa paFederal University yeABC (UFABC) muSão Paulo State, Brazil, yakabatanidza niobium neglycerol mune inovimbisa tekinoroji mhinduro yekugadzirwa kwemafuta emafuta. Chinyorwa chinotsanangura chidzidzo ichi, chakanzi "Niobium inowedzera electrocatalytic Pd chiitiko mualkaline yakananga glycerol mafuta masero," inoburitswa muChemElectroChem uye inoratidzwa pachivharo chejenari.

“Pamusoro pese, sero rinoshanda sebhatiri rine glycerol kuti richajise midziyo midiki yemagetsi yakaita senharembozha kana malaptop. Inogona kushandiswa munzvimbo dzisina kuvharwa nemagetsi emagetsi. Gare gare tekinoroji inogona kuchinjika kuti imhanye mota dzemagetsi uye kunyangwe kupa simba kudzimba. Kune zvisingaperi zvinogoneka kunyorera mukufamba kwenguva, "chemist Felipe de Moura Souza, munyori wekutanga wechinyorwa akaudza. Souza ane yakananga doctorate scholarship kubva kuSão Paulo Research Foundation-FAPESP.

Musero, simba remakemikari kubva kune glycerol oxidation reaction mune anode uye kuderedzwa kwemhepo okisijeni mu cathode inoshandurwa kuva magetsi, ichisiya chete kabhoni gasi nemvura semasara. Mhedzisiro yakakwana ndeye C3H8O3 (liquid glycerol) + 7/2 O2 (oxygen gas) → 3 CO2 (carbon gas) + 4 H2O (mvura yemvura). A schematic inomiririra maitiro inoratidzwa pazasi.

"Niobium [Nb] inobatanidzwa mubasa racho se-co-catalyst, ichibatsira chiito chepalladium [Pd] inoshandiswa semafuta emafuta anode. Kuwedzerwa kwe niobium kunoita kuti huwandu hwepalladium huve nepakati, kuderedza mutengo wesero. Panguva imwechete iyo inowedzera zvakanyanya simba resero. Asi mupiro wayo mukuru kudzikiswa kwechepfu ye electrolytic yepalladium inokonzeresa kuoxidation yepakati iyo inoshambadzirwa zvakanyanya mukushanda kwenguva refu kwesero, senge kabhoni monoxide, "akadaro Mauro Coelho dos Santos, purofesa kuUFABC. , chipangamazano wetisi yehudhokotera hwaSouza, uye muongorori mukuru wechidzidzo ichi.

Kubva pamaonero ezvakatipoteredza, ayo kupfuura nakare kose anofanirwa kuve mucherechedzo wesarudzo wetekinoroji, iyo glycerol fuel cell inoonekwa seyakanaka mhinduro nekuti inogona kutsiva injini dzinopisa dzinofambiswa nefossil.
