配位体修饰氟化锶纳米分层微球的可控合成
|
摘要
以硝酸锶为锶源,氟化钠为氟源,乙二胺四乙酸二钠(EDTANa2)为配位体,经微波促进合成了配位体修饰氟化锶纳米分层微球(1),其结构和形貌经XRD和SEM表征。物料比r[n(EDTANa2)∶n(Sr2+)]和反应温度(t)对1rt形貌影响较大。结果表明,在最佳反应条件[n(Sr2+)5 mmol,r=7,于120℃/600 W反应]下合成的17120分层清晰,分散性好,球体均匀,直径600 nm~800 nm。
Ligand modified Sr F2 hierarchical microspheres( 1) were synthesized by microwave-assisted method,using Sr( NO3)2as the Sr source,Na F as the F source and EDTANa2 as the ligand. The structures and morphology were characterized by XRD and SEM. Mole ratio( r) and reaction temperature( t) exhibited important effects on the microstructure of 1rt. The results showed that the optimum reaction conditions of 1rtwere as follows: n( Sr2+) was 5 mmol,n( EDTANa2) ∶ n( Sr2+) = 7 at 120℃ /600 W. 17120 were in good dispersity and hierarchy. The diameter were 600 nm ~ 800 nm.
