Iplatinam enobungakanani be-nano isetyenziselwa ukulungisa i-titrant.Ngokuqhelekileyo, esi sisombululo se-platinum nano colloid sine-platinum nanoparticles kunye nobukhulu be-particle size, i-concentration ephezulu kunye nokusebenza kakuhle kwe-catalytic, enokuphucula ngokufanelekileyo ukuchaneka kunye nokusebenza kakuhle kokuzimisela kwe-hydrogen.

Enye yezona ndlela zilula kwaye zikhawulezayo zokumisela umxholo we-hydrogen kwisisombululo okwangoku: i-redox titration (MB-nano Pt colloidal solution titration).Umgaqo-siseko kukwenza i-hydrogen ukunciphisa i-methylene blue (MB) nge-pcolloid Pt (nano platinum Pt).I-MB yidayi esetyenziswa ngokuqhelekileyo kunye nesalathisi se-redox titration.Ngenxa yempembelelo ye-covalent bond ye-hydrogen ngokwayo, kunzima kwi-hydrogen ukusabela nge-MB, kodwa phantsi kwe-catalysis ye-colloidal Pt, inokungena kwi-redox reaction kunye ne-hydrogen yobunzima obulinganayo bemolekyuli, kwaye ukusabela kunokwenza umbala oluhlaza okwesibhakabhaka. oxidized MB ibe yi-methylene blue encitshisiweyo (leucoMB/leucomethylene blu): blue MB+2H⁺+2e^-= leucomMB

Isinyathelo esiphambili sokufezekisa iipropati ezintle zePt nano: ngokubhekiselele kwintsimi ethile yeplatinum yokusetyenziswa kwe-catalyst, khetha i-agent efanelekileyo yokusabalalisa kunye ne-stabilizer ukunyusa ukusebenza kwe-catalytic ye-nano-platinum.

I-Breif isingeniso se-nano Pt: Njengezinto ezisebenzayo, i-nano platinum impahla inexabiso elibalulekileyo lesicelo kwiinkalo ze-catalysis, i-sensor, iiseli ze-fuel, i-optics, i-electronics kunye ne-electromagnetism.

Ezi nkcukacha zingentla zenzelwe ireferensi kuphela.Ngeenkcukacha ezithe vetshe, zixhomekeke kwizicelo ezizizo kunye novavanyo.

Iibhetshi zexesha elide ezinomgangatho ophezulu ozinzile kunye ne-multi-specification ye-nano platinum imathiriyeli kunye neenkonzo ezenziwe ngokwezifiso zinikezelwa nguHongwu Nano.

Wamkelekile ukuba uqhagamshelane nathi ngolwazi oluthe vetshe..
