Whakaahuatanga:
Ka whakamahia te konukawata me te rahi nano ki te whakarite i te titrant.I te nuinga o te wa, ko tenei otinga konukawata nano colloid he konukawata nanoparticles me te rahi o te matūriki, te kukū teitei me te pai o te mahi catalytic, ka taea te whakapai ake i te tika me te pai o te whakatau hauwai.
Ko tetahi o nga tikanga tino watea me te tere mo te whakatau i te ihirangi o te hauwai i roto i te otinga i naianei: te titration redox (MB-nano Pt colloidal solution titration).Ko te maataapono ko te whakaheke hauwai o te methylene kahurangi (MB) na te pcolloid Pt (nano platinum Pt).Ko te MB he tohu waikano me te tohu titration redox.Na te awe o te here kovalent o te hauwai ake, he uaua te tauhohenga o te hauwai ki te MB, engari i raro i te catalysis o te colloidal Pt, ka puta he tauhohenga redox me te hauwai o te taumahatanga ngota rite, a ka taea e te tauhohenga te hanga i te kikorangi. Ko te MB kua waikura ka noho hei kikorangi methylene iti (leucoMB/leucommethylene kahurangi): puru MB+2H++2e-=leucoMB
Ko te taahiraa matua ki te whakatutuki i nga ahuatanga pai o te Pt nano: kia rite ki te waahi motuhake o te konukawata mo te tono whakakorikori, whiriwhiria te kaihoko whakamarara me te whakapumau hei whakanui ake i te kaha o te miihini nano-konukawata.
Ko te whakaurunga poto o te nano Pt: Hei rauemi mahi, he uara tono nui te rauemi konukawata nano i roto i nga mara o te catalysis, pūoko, pūtau wahie, optics, hikohiko me te electromagnetism.
Ko nga korero i runga ake nei hei tohutoro anake.Mo etahi atu taipitopito, kei raro i nga tono me nga whakamatautau.
Ko nga kohinga mo te wa roa me te kounga teitei me te maha o nga taputapu nano platinum me nga ratonga kua whakaritea e Hongwu Nano.

Tikanga Rokiroki:
Ko te Collodial Pt me penapena ki roto i te hiri, karohia te waahi marama, maroke me te iti o te pāmahana.Me whakamahi wawe ki te pupuri i te mahi pai.
