Iziphumo zomsebenzi zipapashwa kwimagazini ye-nanomatolika. Ngexesha lokudibana kwe-hydrogen, igesi ye-Greenhouse akwenziwanga, kwaye iiseli ze-upende ezisebenza kwisiseko zayo zivelisa umbane ngokusebenza okuphezulu, kwaye ke i-hydrogen ithathwa njengezithembisayo.
Ukuveliswa kwemveliso yanamhlanje kusekwe kuguqulelo lwegesi yendalo kunye ne-vapor yamanzi eqhutywa kwi-1000 degrees Celbon Diogide esebenza ngegesi ezimbini zegesi - I-Ch4 kunye neCO2. Ngelishwa, i-Cataams yokuguqulwa kwe-Steam kule nkqubo ayisebenzi kwaye itshatyalalisiwe, kwaye ukusetyenziswa kwe-istitalysts ye-Unists esekwe kwiPlatinam Histal Prother (PT, PD, i-PD, i-PD, i-PD, ingenakwenzeka kwizizathu ezahlukeneyo.
Umgqatswa othembisayo we-carbon diokside catalysts yi-molybdenum carbide (mo2c). Umsebenzi wayo wokuthatha inxaxheba kubandakanya i-hydrocarbons yokukhanya iyathelekiswa kwiPlatinam, kwaye ixabiso liphantsi kakhulu. Ukongeza, i-molybdenum carbide ayichasanga kwizinto eziqhelekileyo ze-catalyticals - i-carbon sediments kunye ne-sulfur-enezixhobo ezinamathafa, ezenza ukuba i-catalysts isekwe kumsebenzi omde. Nangona kunjalo, i-molybdenum carbide ayisasazwanga kwindalo kwaye inokufunyanwa kuphela ngokwenza.
Kwindlela ye-meltellical yemveli, iyaqengqeleka ngenxa yokucwangciswa kobushushu bexesha elide kwentsimbi kunye nekhabhoni, okukhokelela ekusebenziseni amandla amakhulu. Enye indlela eqhelekileyo kukuncitshiswa kwe-molybdenum oxidey ngomxube we-hydrocarbon geses ene-H2 okanye imichiza evuyiweyo.
Le ndlela ifuna amandla amancinci, kodwa ifuna amanyathelo okhuseleko ngenxa yokusetyenziswa kweegesi zokuqhushumba. Ukongeza, kuzo zombini iindlela kumphezulu we-molybdenum carbide, ifilimu yekhabhoni yenziwa, ebonisa inxalenye yamaziko akhutheleyo kwaye ke inciphise ukusebenza kakuhle kokusebenzisa izinto. Ke ngoko, izazinzulu zifuna ezinye iindlela zeSynthesi yayo.
Kwi-PCT, i-molybdenum carbide icetywayo ukuba ifumaneke kusetyenziswa indlela ye-synthesi ye-molybdenum eluhlaza okwesibhakabhaka (ebizwa ngokuba kukusasazeka kwe-custerbdenum neoksijini). Kumsebenzi, izazinzulu zenza i-synthesis ye-MO2C ngamanqanaba aliqela. Ekuqaleni bafumana i-molybdenum eluhlaza okwesibhakabhaka ngenxa yokuncitshiswa kwesisombululo se-Amomolbic Ascorbic Acid kubukho be-hydrochloric acid.
Kwaye emva koko i-molybdenum eluhlaza yandoyikiswa kwaye iqulathe irhamncwa le-750-800 eCelsius, ngenxa yoko kwasekwa i-molybnum calbide yedyokhwe. "Umahluko ophambili womsebenzi owenziwa liqela lethu lesayensi yindlela edityanisiweyo," chaza omnye wababhali, unjingalwazi odibeneyo weSebe leColoid Chemistry of Putnu, Natalia Guvrilova.
Ngapha koko, asizibandakanyekisi kuphela kwi-synthesis yesuntswana, kodwa sifunda kwinqanaba ngalinye lokufumana iinkqubo zentlekele, ezivumela, ukumisela iipatheni ezisisiseko, ukuba, i-molybdenum carbide yemoto Umsebenzi ophezulu. "
Kumsebenzi, abaphandi batshintsha umyinge wezixhobo ze-molybdenum kunye nearhente yokunciphisa kwinqanaba lokuqala le-synthen kwaye bafunda ubume be-molybdenum blueblebdenum kunye ne-molybdenum ye-DEYE kwidayi. Umsebenzi we-Mo2c wavavanywa ngokwenza indlela yokuphendula ye-methane ch4 (icandelo legesi yendalo) kunye ne-CO2 kumxube we-H2, i-HOLTEIS, oko kukuthi, igesi ye-HOLTEIS.
Ibonisiwe ukuba sele inobushushu obuyi-850 degrees celsius, inqanaba le-methane liguqulwe yi-100 pesenti, kwaye iisampulu zihambelane nomsebenzi ophezulu wearhente kumxube wokuqala: kunye nawo ukuguqulwa I-Ch4 kunye ne-CO2 kwi-synthesige yegesi yenzeka.
Ke, izazinzulu zifumanise ukuba eyona ndima iphambili ekusekweni kwesakhiwo kunye nokuhlengahlengiswa kwe-cataralstral idlala iarhente yokunciphisa kwaye, ngokutshintsha komxholo wayo kwi-molybdenum carbide kwaye ihlengahlengise ubume obuqhelekileyo yekati.
Indlela eyaphuhliswayo ye-synthes ihamba ngamaqondo obushushu aphantsi (xa kuthelekiswa neendlela zemveli), kwaye i-MOTTETE inomsebenzi ophezulu osebenzisa le ndlela yokufumana le ndlela iphambili kwi-cataiers kunye ne-catalytic emisebenzini eyahlukeneyo - kubandakanya ukuguqulwa kwegesi yendalo.
