Abstract

The present invention provides a "copolymer-comorphology" strategy to precisely control A y B 1‑y [Co(CN) 6 ] 0.67 Morphology of PBA metal-organic coordination polymers. In PVP solution, by preparing a solid solution solution of two hexacyanocobaltates (A‑Co and B‑CoPBA), A with specific morphology can be prepared. y B 1‑y [Co(CN) 6 ] 0.67 PBA. In addition, through simple heat treatment, doped porous transition metal oxide A with specific morphology can be synthesized x B 1.8‑ x co 1.2 o 4 . Using the morphology-controllable synthesis strategy, Mn with specific morphology can be easily synthesized by simply changing transition metal precursors. y Fe 1‑y [Co(CN) 6 ] 0.67 and Zn y Fe 1‑y [Co(CN) 6 ] 0.67 PBA. Compared with other methods in the literature, this morphology synthesis strategy has the characteristics of precisely controlling the morphology and composition of nanomaterials, and has strong scalability.

Description

technical field [0001] The present invention relates to the use of a shape-controllable hybrid metal-organic coordination polymer (A y B 1-y [Co(CN) 6 ] 0.67 PBA) method, at the same time, simple heat treatment, the copolymer can be easily transformed into a doped porous transition metal oxide (A x B 1.8-x co 1.2 o 4 ). Background technique [0002] In recent years, metal-organic coordination polymers (MOFs) and doped transition metal oxides (MTMOs) have been widely used in the fields of battery electrode reaction, photocatalysis, Fenton reaction, magnetic materials, etc. It is well known that the morphology, composition and specific surface area of ​​nanomaterials have a great influence on the physical and chemical properties of materials. Therefore, the morphology-controllable synthesis of nanomaterials has become a hot spot in the study of functionalization in recent years. There are also many methods for preparing MOFs and MTMOs with traditional morphology contr...
