Platinum nrog nano loj yog siv los npaj cov titrant.Feem ntau, cov tshuaj platinum nano colloid no muaj platinum nanoparticles nrog qhov loj me me, siab concentration thiab zoo catalytic kev ua tau zoo, uas tuaj yeem txhim kho qhov tseeb thiab kev ua haujlwm ntawm kev txiav txim siab hydrogen.

Ib txoj hauv kev yooj yim tshaj plaws thiab nrawm rau kev txiav txim siab cov ntsiab lus ntawm hydrogen hauv kev daws tam sim no: redox titration (MB-nano Pt colloidal tov titration).Lub hauv paus ntsiab lus yog catalyze hydrogen txo ntawm methylene xiav (MB) los ntawm pcolloid Pt (nano platinum Pt).MB yog ib qho uas nquag siv dye thiab redox titration qhia.Vim yog qhov cuam tshuam ntawm covalent daim ntawv cog lus ntawm hydrogen nws tus kheej, nws nyuaj rau hydrogen kom hnov ​​​​mob MB, tab sis nyob rau hauv catalysis ntawm colloidal Pt, nws muaj peev xwm undergo ib redox cov tshuaj tiv thaiv nrog hydrogen ntawm qhov sib npaug molecular hnyav, thiab cov tshuaj tiv thaiv yuav ua rau xiav. oxidized MB ua tus txo methylene xiav (leucoMB / leucomethylene xiav): xiav MB + 2H⁺+2 e^-= leucoMB

Cov kauj ruam tseem ceeb kom ua tiav cov khoom zoo ntawm Pt nano: raws li qhov tshwj xeeb ntawm platinum rau daim ntawv thov catalyst, xaiv tus neeg sawv cev tsim nyog thiab stabilizer kom ua kom cov catalytic efficiency ntawm nano-platinum.

Breif qhia txog nano Pt: Raws li cov khoom siv ua haujlwm, cov khoom siv nano platinum muaj cov txiaj ntsig tseem ceeb hauv kev lag luam catalysis, sensors, roj hlwb, optics, electronics thiab electromagnetism.

Cov ntaub ntawv saum toj no tsuas yog siv rau kev siv xwb.Yog xav paub ntxiv, lawv raug rau cov ntawv thov thiab kev xeem.

Cov khoom siv mus sij hawm ntev nrog kev ruaj khov zoo thiab ntau cov ntaub ntawv nano platinum thiab cov kev pabcuam customized yog muab los ntawm Hongwu Nano.
