Incazelo:
I-Nano-platinum iyi-catalyst engathuthukisa ukusebenza kahle kokunye ukusabela kwamakhemikhali okubalulekile.Izinto zokwenziwa kwe-electrocatalytic ezisekelwe kukhabhoni zeplatinamu zisetshenziswe kabanzi ekunciphiseni i-cathode kanye nokusabela kwe-anodic oxidation yamaseli kaphethiloli.
I-Methanol fuel cell iyi-proton exchange membrane fuel cell esebenzisa i-methanol njengophethiloli owuketshezi.Ayinayo nje kuphela izinzuzo zemithombo kaphethiloli eningi, izindleko eziphansi, isitoreji esikahle nesiphephile nezokuthutha, kodwa futhi i-methanol inomthamo omkhulu wamandla futhi idonse ukunaka okusabalele.Kodwa-ke, ukuthuthukiswa kwamaseli kaphethiloli we-methanol kunqunyelwe ukusabela kancane kwe-kinetics ye-anode methanol reaction kanye nokuba sengozini yobuthi bensimbi ye-platinum catalyst, futhi kuyadingeka ukwandisa ukulayishwa kweplatinamu.Ngakho-ke, inani lamasayithi asebenzayo adaluliwe kanye nesakhiwo esingaphezulu, ukwakheka kanye nokuhlelwa kwe-athomu ye-catalyst kubaluleke kakhulu ukuthuthukisa izinga lokusebenzisa i-platinum nokusebenza kwe-catalytic.Njengamanje, kunenani elikhulu locwaningo olugxile ekuhloleni izinsimbi ezihlukene zoguquko kanye neplatinamu ukwenza ama-alloys noma ama-heterostructure catalysts ukuze kuguqulwe ukwakheka kwe-platinamu kagesi ukuze kufezwe injongo yokunciphisa ukulayishwa kweplatinum nokwandisa ukusetshenziswa kweplatinamu.
I-Nano platinum ingasetshenziswa futhi njengezinzwa ze-electrochemical kanye nama-biosensors ukuthola i-glucose, i-hydrogen peroxide, i-formic acid nezinye izinto.
Inothi lokuhlakazeka:
1. Ivalwe kahle futhi uyigcine endaweni enezinga lokushisa eliphansi.
2. Sicela usebenzise ama-dispersions maduze phakathi nenyanga eyodwa ngemuva kokuthola izimpahla.
