【摘要】:以鈦酸正四丁酯作為鈦源,乙酰丙酮作為螯合劑來抑制鈦酸正四丁酯的水解,十六烷基三甲基溴化銨陽離子表面活性劑作為為模板,采用超聲模板法制備出球形銳鈦礦介孔TiO_2,采用兩步焙燒法除去模板劑。FT-IR測(cè)試表明在478cm-1出現(xiàn)介孔TiO_2特征峰,XRD測(cè)試表明合成的樣品為銳鈦礦介孔TiO_2,TG-DTA測(cè)試表明合成的樣品熱穩(wěn)定性較好,SEM測(cè)試表明樣品為球形顆粒且形狀均勻,TEM測(cè)試表明粒子的分散性很好,維持了很好的介孔結(jié)構(gòu)。結(jié)果表明:合成的介孔TiO_2晶型有較好的完整性。
[Abstract]:With titanate as titanium source was four butyl, hydrolysis of acetylacetone as chelating agent to inhibit four butyl titanate, sixteen alkyl three methyl bromide cationic surfactant as template, the template was prepared by ultrasonic spherical mesoporous anatase TiO_2, using two stage roasting method to remove the template.FT-IR test showed that 478cm-1 appeared in the mesoporous TiO_2 peak, XRD test showed that the samples were anatase mesoporous TiO_2, TG-DTA test showed that the thermal stability of synthetic samples better, SEM test showed that the sample is spherical particles and uniform shape, TEM tests show that the particle dispersion is good, maintain a good mesoporous structure. The results show that the mesoporous TiO_2 crystal synthesis has better integrity.
