Controlled Synthesis of Cellular Mesoporous Nanoreactors Containing Cobalt Oxide and Their Application in Dye Degradation
Cellular mesoporous silica nanoreactors containing cobalt oxide(CoxOy@CMSNs)were prepared by one-step method using micelles formed by CTAB and 1-dodecanethiol in water as templates.The degradation effect of different types of dyes by CoxOy@CMSNs and CoxOy/SiO2 were studied.The effects of synthetic conditions and the catalytic parameters for degradation of dyes on the degradation efficiency for CoxOy@CMSNs were investigated,and the stability of the nanoreactor with the best catalytic effect was studied.Compared with the supported catalyst,CoxOy@CMSNs has shown excellent catalytic activity,stability,and dye suitability,mainly attributed to highly dispersed CoxOy,rich pore structure,high specific surface area,and unique cellular structure of CoxOy@CMSNs.
