摘要

1,4,7,10-四氮杂环十二烷-1,4,7,10-四基-四(甲基膦酸)（DOTMP）和 Zr4+ 离子在酸性水溶液中反应合成了一种具有多级多孔结构和高比表面积（约 408.6 m2/g）的新型膦酸锆材料 ZrDP。在材料中发现，DOTMP 中的 1,4,7,10-四氮杂环十二烷具有直径约 0.64 nm 的微孔，而结构中的孔隙直径约为 1.68 nm。在 ZrDP 的骨架上配位了一些金属离子，形成了 M@ZrDP 复合材料，在苯甲醇到苯甲醛的选择性氧化反应中，Cu(II)@ZrDP 表现出很高的催化活性，选择性达到 90.2%。

A new kind of hierarchical porous zirconium phosphonate: preparation and application on oxidation catalysis

A kind of new zirconium phosphonate material ZrDP with multilevel porous structure and high surface area (about 408.6 m²/g) was synthesized by the reaction between 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetrayl-tetrakis(methylphosphonic acid) (DOTMP) and Zr⁴⁺ ions in acidic water solution. Micropores with diameter about 0.64 nm from 1,4,7,10-tetraazacyclododecane in DOTMP and the pores with diameter about 1.68 nm from structure were found in the material. Some metallic ions were coordinated on the skeleton of ZrDP to form composites M@ZrDP and Cu(II)@ZrDP exhibited high catalytic activity in the selective oxidation reaction from benzyl alcohol to benzaldehyde with 90.2% selectivity.

期刊介绍： The Journal of Porous Materials is an interdisciplinary and international periodical devoted to all types of porous materials. Its aim is the rapid publication of high quality, peer-reviewed papers focused on the synthesis, processing, characterization and property evaluation of all porous materials. The objective is to establish a unique journal that will serve as a principal means of communication for the growing interdisciplinary field of porous materials. Porous materials include microporous materials with 50 nm pores. Examples of microporous materials are natural and synthetic molecular sieves, cationic and anionic clays, pillared clays, tobermorites, pillared Zr and Ti phosphates, spherosilicates, carbons, porous polymers, xerogels, etc. Mesoporous materials include synthetic molecular sieves, xerogels, aerogels, glasses, glass ceramics, porous polymers, etc.; while macroporous materials include ceramics, glass ceramics, porous polymers, aerogels, cement, etc. The porous materials can be crystalline, semicrystalline or noncrystalline, or combinations thereof. They can also be either organic, inorganic, or their composites. The overall objective of the journal is the establishment of one main forum covering the basic and applied aspects of all porous materials.
