Fa'amatalaga:
Nano-platinum o se faʻamalosi e mafai ona faʻaleleia atili le lelei o nisi gaioiga faʻainisinia taua.O mea fa'aeletise e fa'atatau i le platinum e lagolagoina kaponi ua fa'aaogaina lautele i le fa'aitiitia o le cathode ma le anodic oxidation reactions o suau'u suauu.
Methanol suau'u cell o se proton exchange membrane suauu suauu e fa'aogaina le methanol e fai ma suau'u vai.E le gata o loʻo i ai le lelei o le tele o suauʻu, tau maualalo, faigofie ma saogalemu le teuina ma felauaiga, ae o le methanol foi e maualuga le malosi o le malosi ma ua tosina atu ai le lautele.Ae ui i lea, o le atinaʻeina o sela suauʻu methanol e faʻatapulaʻaina e le faʻagesegese o le tali atu o le anode methanol reaction ma le faʻaogaina o le faʻamaʻi o le uʻamea platinum, ma e tatau ona faʻateleina le utaina o le platinum.O le mea lea, o le numera o nofoaga o loʻo faʻaalia ma le fausaga o luga, tuʻufaʻatasiga ma le faʻatulagaina o atomic o le catalyst e taua tele e faʻaleleia ai le faʻaogaina o le platinum ma le faʻatinoina o galuega.I le taimi nei, o loʻo i ai le tele o suʻesuʻega o loʻo taulaʻi i le suʻesuʻeina o uʻamea suiga eseese ma le platinum e faʻapipiʻi ai alloys poʻo heterostructure catalysts e faʻaleleia ai le fausaga eletise eletise e ausia ai le faʻamoemoe o le faʻaitiitia o le utaina o le platinum ma faʻateleina le faʻaogaina o le platinum.
E mafai fo'i ona fa'aogaina le Nano platinum e fai ma masini eletise ma biosensors e iloa ai le kulukose, hydrogen peroxide, formic acid ma isi mea.
Fa'aaliga mo fa'asalalauga:
1. Fa'amaufa'ailoga lelei ma teu i totonu ole si'osi'omaga maualalo le vevela.
2. Fa'amolemole fa'aaoga fa'asalalau vave i totonu o le masina e tasi ina ua maua oloa.
