Probing the Lewis Acid Sites and CO Catalytic Oxidation Activity of the Porous Metal−Organic Polymer [Cu(5-methylisophthalate)]

Abstract

The oxidation of CO to CO 2 by metal catalysts has been intensively investigated; for example, gold nanoparticles have exhibited excellent properties. 1 The metal catalysts are often dispersed on a solid support, such as oxide, zeolite, and so on. Exposed to heating during vehicle use, these metal particles trend to agglomerate and grow, which causes their overall surface area to decrease. As a result, catalyst activity deteriorates. 2 These metal catalysts are also very easily poisoned by exposing them to moisture or organic compounds. On the other hand, the newly developed microporous metal-organic polymers (MMOPs) have recently

“…There is considerable interest in the study of transition complexes containing carboxylate ligands due to their novel topology and excellent properties [1][2][3][4][5][6]. Furthermore, zinc, as one of the most important trace elements, plays aversatile role in biological systems caused by itsstructuraland catalyticrole in enzymes [7,8].…”

“…An effective approach in building such materials is to employ suitable organic bridging ligands [6,7]. Carboxylatecontaining ligands have attract considerable interest in reported multidentate ligands because of their diverse coordination modes [8][9][10][11][12]. Furthermore, it is found flexible ligands may induce novel topologies owing to their flexibility and conformation freedoms [13].…”

Ligand Structure Induced Diversification from Dinuclear to 1D Chain Compounds: Syntheses, Structures and Fluorescence Properties

“…Each pair of Zn(II) ions is bridged by double Hfhba ligands to form a dinuclear compound. The ZnÁÁÁZn distance of 4.341 Å is longer than the ZnÁÁÁZn distance in the other dimeric zinc(II)-carboxylato complex [Zn 2 (bpy) 2 (-MeCO 2 ) 3 ]ÁC1O 4 (bpy = 2,2 0 -Bipyridine, 3.275 Å ) [15]. The Hfhba ligand displays Figure S2).…”

“…In the past decades, metal-organic coordination compounds have raised an upsurge of interest in the fields of crystal engineering and functional materials, due to their intriguing structural features as well as desired properties [1][2][3][4][5][6][7][8][9][10][11][12][13] including chirality, catalysis, porosity, non-linear optics, magnetism, ferroelectrics and luminescence [14][15][16][17][18][19][20][21][22][23]. Studies in this field have been focused on the design and construction of new metal-organic coordination compounds and the relationships between their structures and properties.…”
