Hollow spheres, raws li hom tshiab ntawm cov khoom, yog tus cwj pwm los ntawm qhov chaw loj sab hauv thiab lub plhaub txheej nrog lub thickness ntawm nanoscale ntau. Cov qauv tshwj xeeb no tau txuas ntxiv nthuav dav nws daim ntawv thov mus rau ntau qhov chaw xws li cov ntaub ntawv kev tshawb fawb thiab kev lag luam dyeing, thiab tseem tuaj yeem siv los ua cov khoom siv sib xws, rwb thaiv tsev, suab rwb thaiv tsev, thiab cov khoom siv hluav taws xob. Tam sim no, ntau txoj kev npaj ntawm hollow spheres tau tsim, xws li qauv qauv, adsorption technology, tshuaj tsuag pyrolysis txoj kev, ultrasonic chemical method, hydrothermal method, chemical induced autorotation method, thiab lwm yam.
Aluminium oxide yog cov khoom ntxeem tau thiab cov khoom tawg yooj yim heev nrog kev ua haujlwm zoo adsorption, deg acidity, thiab thermal stability. Aluminium oxide tau pom qhov zoo tshwj xeeb hauv catalysis.
