中文摘要: |
以CTAB和十二硫醇在水相中形成的胶束为模板,一步法合成含氧化钴的蜂窝状介孔纳米反应器(CoxOy@CMSNs)。研究了CoxOy@CMSNs和负载型催化剂(CoxOy/SiO2)对不同类型染料的降解效果,同时考察了合成条件和催化反应参数对降解效果的影响,并对最优效果的催化剂进行了稳定性测试。结果表明,相比于负载型催化剂,CoxOy@CMSNs展现出了优异的催化活性、稳定性和染料适用性,这主要归因于CoxOy@CMSNs中高度分散的CoxOy、丰富的孔结构、高比表面积和独特的蜂窝状结构。 |
英文摘要: |
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 for CoxOy@CMSNs and the catalytic parameters for degradation of dyes on the degradation efficiency 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. This are mainly attributed to CoxOy@CMSNs highly dispersed CoxOy, rich pore structure, high specific surface area, and unique cellular structure. |
