後修飾孔洞性鉻金屬有機骨架的吸水性能研究

主要研究目的在於提供研磨加熱法合成鉻金屬有機骨架(Chromium-based Metal Organic Framework, Cr-MOF)。Cr-MOF合成不需添加溶劑和催化劑。Cr-MOF的結構、形態、孔洞分布與比表面積分別通過粉末X射線衍射（PXRD）、掃描電子顯微鏡（SEM）和氣體吸脫附儀鑑定。此外，Cr-MOF的結構具有良好水氣穩定性，將其應用於水的吸附劑。第二部分藉由後修飾的方式，將磷酸修飾到中心金屬空配位上，針對修飾後的Cr-MOF作吸水性能及降低活化條件測試:0.5 M H3PO4@Cr-MOF 1.0 M H3PO4@Cr-MOF 對其結果作比較及討論，探討後修飾對於Cr-MOF吸水性能及降低活化條件的比較。以上所有的MOFs均以粉末以桌上型恆溫恆濕試驗機來檢測化合物的吸水性能。

The cardinal search is with the aim of tendering the lapping heating a law synthesis chromium metalloporphyrin organic skeleton.(Chromium-based Metal Organic Framework, Cr-MOF)The Cr-MOF synthesis doesn't need to add solvent and catayst.Cr-MOF of structure, situation and hole the rayleing distribution rayleigh and specific surface integral don't shoot(PXRD) through dust X ray Yan, scanning electron microscope(SEM) and gas suction take off to attach the instrument appraiser.In addition, the structure of the Cr-MOF has the good aqueous vapor stability, it is at the adsorbent of aqua to apply it. Second fraction by polishing behind of mode, polish the ddvp to the metalloporphyrin for nothing in center to go together with in, the Cr-MOF after aiming at the finishing absorbs water the activate condition test of properties and step - down: 0.5 M H3PO4@Cr-MOF 1.0 M H3PO4@Cr-MOF Make compare and discussion as a result to it, the study polishes to absorb water the properties and step - down for the Cr-MOF the activate behind the compare under condition. Above possessive MOFs all with dust with desktop constant temperature Heng wet tester to examine the absorption of water properties of compound.
