Phosphothermal (high F-, low OH-) Synthesis and Characterization of the Novel Transition-Metal Fluorophosphates

Abstract

过渡金属氟磷酸盐在锂离子电池、多孔吸附、磁性和催化等领域均有着广泛的应用,但过渡金属氟磷酸盐体系经历了几十年的发展,却因合成方法上一直未有突破而进展缓慢。由此,本文作者提出一种有效的合成氟磷酸盐的富F-贫OH-的磷酸溶剂热法,并运用此方法合成出30余种新化合物晶体。主要结果如下: (1)该论文探索总结出一种合成混合高价锰的新方法,合成出首个具有特异多级类clathrate结构的新型混合高价锰(Mn3+/Mn4+)氟磷酸盐MnIII6F12(PO3(OH))8[Na8K3.74((H3O)0.26(H2O)2)MnIV(OH)6](MN)。该化合物为[MnIIIO4F2]八面体和[HPO4]四...Transition metal fluorophosphates have a wide range of applications in lithium batteries, porous materials, magnetism, catalysis and so on. However, it expanded slowly for many years because of no major breakthrough on the synthetic methods. Hence, the author provides a new, efficient phosphothermal route with a very low OH-, high F- content system for the synthesis of transition metal fluorophosp...学位:工学硕士院系专业:材料学院_材料物理与化学学号:2072012115002
