| Abstract: | The mesoporous silica material was synthesized by pre-hydrolytic two-step method when above the isoelectric point of silica in acidic condition(pH=2~5).The ethoxylated derivatives of fatty esters of sorbitan(Tween20)was used as the template.It was found that the factors of acidity,inorganic salt have significant effects on the synthesized mesoporous silica material |
