I-Platinam palladium yentsimbi exabisekileyo ye-catalyst yi-catalyst yonyango ye-gas esebenza ngokufanelekileyo, yenziwe nge-Pt kunye ne-Pd kunye nezinye iintsimbi ezixabisekileyo, ngoko inomsebenzi ophezulu kakhulu we-catalytic kunye nokukhetha.Iyakwazi ukuguqula ngokufanelekileyo izinto ezinobungozi kwigesi yokukhupha kwaye iguqule ibe zizinto ezingenabungozi, ngaloo ndlela inciphisa ukukhutshwa kwegesi yokukhupha kunye nokukhusela okusingqongileyo kunye nempilo yabantu esixhomekeke kuyo.
Amacandelo angundoqo eplatinam kunye ne-palladium catalysts zintsimbi ezixabisekileyo ezifana neplatinam kunye ne-palladium, kwaye ukhetho lwezi zinyithi zixabisekileyo lukhetheke kakhulu, ngokuxhomekeke ngokupheleleyo kwimeko yesicelo se-catalyst kunye neemfuno ze-catalytic reaction.Ngokuqhelekileyo, ubungakanani be-platinum kunye ne-palladium kwi-platinum kunye ne-palladium catalysts yi-1: 1 okanye i-2: 1, kwaye lo mlinganiso unokufezekisa umphumo ongcono we-catalytic.Ukongezelela, inkxaso ye-platinum palladium catalyst nayo ibaluleke kakhulu, enempembelelo enkulu ekusebenzeni kwe-catalyst.Abathwali abaqhelekileyo yi-aluminium oxide, i-silicon oxide, i-yttrium oxide, njl., Enika i-substrate ezinzileyo ye-catalyst kwaye iqinisekisa umphumo osebenzayo kakhulu.
Iindlela eziqhelekileyo zokulungiselela i-platinum kunye ne-palladium catalysts ziquka ukukhulelwa, i-co-precipitation, imvula, ukuxubana ngokomzimba kunye nokunye.Indlela yokufakelwa kukukhupha umthwali ongalunganga (ngokuqhelekileyo i-oxide) kwisisombululo esine-platinum kunye ne-palladium ion, kwaye emva koko uqhube uchungechunge lwemisebenzi efana nokumisa kunye nokunciphisa, kwaye ekugqibeleni ufumane i-platinum kunye ne-palladium catalyst.Indlela coprecipitating kukuba carrier negative kunye platinum kunye ion palladium zongezwa kwinkqubo yokusabela kunye, kunye neplatinam kunye ne-palladium ion zixakeke kunye phezu komphezulu ophethe kakubi ukwenza iplatinum kunye ne-palladium catalyst ngokulawula ixabiso le-pH kwaye ubushushu besisombululo.I-platinum palladium catalyst efunyenwe yile ndlela ineempawu zomsebenzi ophezulu, ukukhetha okuphezulu kunye nokuzinza okuphezulu, okuqinisekisa ukusebenza kakuhle kunye nokhuseleko lonyango lwegesi yenkunkuma.
Xa usebenzisa i-platinum kunye ne-palladium i-catalysts yentsimbi exabisekileyo, kufuneka sinikele ingqalelo kwimicimbi yokhuseleko.Okokuqala, kuyimfuneko ukuphepha iimeko ezinobungozi ezifana nedangatye elivulekileyo, ubushushu obuphezulu kunye nombane ongatshintshiyo, nto leyo enokukhokelela ekuwohlokeni kokusebenza kwe-catalyst kunye nobungozi.Okwesibini, i-catalyst kufuneka ihlolwe kwaye itshintshwe rhoqo ukuze kuqinisekiswe ukusebenza kwayo okuqhelekileyo kunye nokufezekisa i-catalytic effect.
