Sharaxaad:
Nano-platinum waa kicinta hagaajin karta waxtarka fal-celinta kiimikada qaarkood.Qalabka korantada ee platinum-ku-salaysan ee kaarboon-ku-salaysan ayaa si weyn loogu isticmaalay dhimista cathode-ka iyo falcelinta oksaydhka anodic ee unugyada shidaalka.
Unugga shidaalka ee Methanol waa unugga shidaalka xuubka beddelka borotoonka kaasoo u isticmaala methanol shidaal dareere ah.Ma aha oo kaliya faa'iidooyinka ilaha shidaalka ee badan, qiimaha jaban, kaydinta iyo gaadiidka ku habboon oo badbaado leh, laakiin sidoo kale methanol wuxuu leeyahay cufnaanta tamarta sare waxayna soo jiidatay dareenka baahsan.Si kastaba ha noqotee, horumarinta unugyada shidaalka methanol waxaa xaddidaya dhaqdhaqaaqa falcelinta gaabis ah ee falcelinta methanol anode iyo u nuglaanshaha sunta birta birta ah ee platinum, waana lagama maarmaan in la kordhiyo culeyska platinum.Sidaa darteed, tirada goobaha firfircoon ee bannaanka ah iyo qaabka dusha sare, halabuurka iyo habaynta atomiga ee kicinta ayaa aad muhiim u ah si loo hagaajiyo heerka isticmaalka platinum iyo waxqabadka catalytic.Waqtigan xaadirka ah, waxaa jira xaddi badan oo cilmi-baaris ah oo diiradda lagu saarayo sahaminta biraha kala-guurka ee kala duwan iyo platinum si ay u sameeyaan alloys ama heterostructure kicin si wax looga beddelo qaab-dhismeedka elektaroonigga ah ee platinum si loo gaaro ujeedada dhimista rarka platinum iyo kordhinta isticmaalka platinum.
Nano platinum waxa kale oo loo isticmaali karaa sida dareemayaasha kiimikaad ee korantada iyo biosensors si loo ogaado gulukoosta, hydrogen peroxide, formic acid iyo walxaha kale.
Xusuusin kala firidhsan:
1. Si naxariis leh u xidh oo ku kaydi deegaan heerkulkiisu hooseeyo.
2. Si naxariis leh u isticmaal kala firdhisyada hal bil gudaheed markaad alaabta hesho.
