Zotsatira za ntchitoyi zimafalitsidwa m'magazini ya nanomariums. Panthawi ya haidrojeni, mpweya wobiriwira supangidwa, ndipo ma cell amafuta omwe amagwirira ntchito pamagetsi amatulutsa magetsi kwambiri, ndipo chifukwa chake hyrogen imawerengedwa bwino kwambiri.
Kupanga kwake kwa mafakitale kumachokera pagulu lachilengedwe pamodzi ndi nthunzi yamadzi ku Celsius, koma njira yochezeka yothetsera miyala ya kaboni, koma malo obiriwira omwe mpweya wa wowonjezera kutentha umagwira nthawi imodzi - CH4 ndi CO2. Tsoka ilo, kutembenuka kotenthetsa mu njirayi kumayatsidwa, ndikuwonongedwa, komanso kugwiritsa ntchito zopereka zadziko lonse lapansi zochokera pazitsulo za platinamu (PT, RH) ndizosathekanso pazifukwa zosiyanasiyana.
Wolosera wolonjezedwa kuti asunge carbon dioctalys ndi Molybdenum Carbide (Moo2c). Ntchito yake yogwira ntchito yokhudzana ndi ma hydrocarbons imafananizidwa ndi platinamu, ndipo mtengo wake ndi wotsika kwambiri. Kuphatikiza apo, Molybdenum carbident amalimbana ndi zingwe zofala za ma calytic - kaboni zopepuka ndi mankhwala a sulufule, zomwe zimapangitsa othandizira kutengera nthawi yayitali. Komabe, Molybdenum carbide samagawidwa mwachilengedwe ndipo amatha kupezeka ndi kupanga.
Mwanjira yachikhalidwe, imapangidwa chifukwa cha kutentha kochepa kwa kutentha kwa chitsulo ndi kaboni, komwe kumabweretsa mphamvu yayikulu yamagetsi. Njira inanso yofala ndi kuchepetsedwa kwa kutentha kwa molybdenum ma oxides ndi chisakanizo cha mpweya wa hydrocarbon ndi mankhwala a H2 kapena Opeka.
Njirayi imafunikira mphamvu zochepa, koma zimafunikira njira zotetezera chifukwa chogwiritsa ntchito mpweya wophulika. Kuphatikiza apo, m'njira zonse ziwiri pamtunda wa Carbide wa Molybdenum, filimu ya kaboni imapangidwa, yomwe imalepheretsa gawo la malo ochitira masewera olimbitsa thupi ndipo motero limachepetsa mphamvu pogwiritsa ntchito zinthuzo. Chifukwa chake, asayansi akuyang'ana njira zina za kaphatikizo wake.
Mu Ptultu, Molybdenum Carbide akufunsidwa kuti athe kugwiritsa ntchito njira yamadzi amtundu wa Molybdenum masamba a Molybdenum ndi okosijeni). Mu ntchito, asayansi adapanga kaphatikizidwe ka MO2C m'magawo angapo. Poyamba adalandira molybdenum amtundu chifukwa kuchepetsa ammonium heptuum heptolibdate solution ascorbic acid pamaso pa hydrochloric acid.
Ndipo kenako Molybdenum Blue adawuma komanso kuwola mwamphamvu pa kutentha kwa 70-800 digiri Celsius, chifukwa cha ku Molybdenum Carbide adapangidwa. "Kusiyana kwakukulu kwa ntchito yomwe tasankha yasayansi ndi njira yophatikizira," yomwe alefe amafotokoza kuti ndi gawo loti,
M'malo mwake, sitingokhala ndi kaphatikizidwe kazinthu zomwe zimabalalika, koma timaphunzira gawo lililonse lopeza, zomwe zimalola, kukhazikitsa njira zoyambira, kuti zisapangidwe ndi zomwe zidanenedwa - ndiye, Molybdenum carbide ndi ntchito yayikulu. "
Kuntchito, ofufuzawo adasintha chiwerengero cha zinthu zokhala ndi zinthu zokhala ndi zinthu zoyambirira za synthesis ndi zomwe zimawerengedwa molybdenum buluu ndi molbdenum kachilombo kameneka, yomwe imakhazikika mtsogolo kuchokera ku utoto. Ntchito yothandizira ku Mo2C idawunikiridwa pochita kutembenuka kwa methane ch4 (gawo lalikulu la mpweya wachilengedwe) ndi CO2 mu osakaniza a H2, Co2 mwa osakaniza a H2, Co2 ndi synthesis mpweya.
Zawonetsedwa kuti kale ndi kutentha kwa madigiri 850 Celsius, kuchuluka kwa kutembenuka kwa Methane, ndi zitsanzo zophatikizika ndi zotsatsa zosemetsera zosakaniza zosakanikirana: Ch4 ndi CO2 mu synthesis mpweya umachitika.
Chifukwa chake, asayansi adazindikira kuti gawo lalikulu pakupanga kapangidwe kake ndi kapangidwe kake kamene kamapanga kuti muchepetse mphamvu, ndizotheka kupeza zosintha zosiyanasiyana za Molybdenum Carbide ndikusintha mawonekedwe za chothandizira.
Njira yotukuka yopangidwa ndi kaphatikizidwe imayenda motentha (poyerekeza ndi njira zachikhalidwe), ndipo mankhwalawa moo2c ali ndi ntchito yayikulu yogwiritsira ntchito njirayi kuti athe kupeza njira yonyamula katundu ndi ma calytic a ntchito zosiyanasiyana - kuphatikiza kutembenuka kwa mpweya wachilengedwe.
