Manganese dioxide hmoov nanoMnO2 nanopowder / nanoparticles
Khoom piav qhia rau manganese dioxide MnO2 hmoov:
Manganese(IV) dioxide MnO2 yog inorganic compound nrog cov mis MnO 2. Cov khoom dub los yog xim av no tshwm sim ib txwm muaj raws li cov ntxhia pyrolusite, uas yog lub ntsiab ore ntawm manganese thiab ib feem ntawm manganese nodules.Lub hauv paus tseem ceeb siv rau MnO 2 yog rau cov roj ntsha qhuav, xws li roj teeb alkaline thiab zinc-carbon roj teeb.MnO 2 kuj yog siv los ua cov xim thiab ua cov khoom ua ntej rau lwm cov manganese tebchaw, xws li KMnO 4. Nws yog siv los ua ib qho reagent hauv organic synthesis, piv txwv li, rau oxidation ntawm allylic alcohols.MnO 2 nyob rau hauv α polymorph tuaj yeem koom nrog ntau yam atoms (nrog rau cov dej molecules) hauv "tunnels" lossis "channels" ntawm magnesium oxide octahedra.Muaj kev txaus siab rau α-MnO 2 raws li qhov ua tau cathode rau lithium ion roj teeb.
