Isingeniso: Ama-catalysts ajwayelekile we-platinum adlala indima ebalulekile embonini yamakhemikhali, ikakhulukazi emkhakheni wezithasiselo kanye nabasizi bamakhemikhali, ikakhulukazi ama-catalysts. Lawa ma-catalysts asetshenziswa kabanzi ukuthuthukisa ukusebenza kahle nokukhethwa kokuphendula kwamakhemikhali. Kulesi sihloko, sizohlola ezweni lama-platinum catalysts ajwayelekile, sihlola izakhiwo zawo, izicelo
