One Functionalized Polyoxovanadates Hybrid Material Based on Arsonic Acid with Highly Effective Catalytic Property of Sulfides

In this work, a novel 4-aminophenylarsonic acid functionalized polyoxovanadates (POVs) hybrid material, namely, (Me2NH2)4 ·[(L)8(H12V16O32)] (H2L = 4-NH2C6H4AsO3H2) POVs 1 was solvothermally synthesized and fully characterized. The results revealed POVs 1 consists of four similar tetranuclear vanadium clusters bridged by eight organic 4-aminophenylarsonic acid ligands. Remarkably, functionalized hybrid POVs 1 was further investigated as a heterogeneous stable catalyst in oxidation of sulfide derivatives, and exhibited high catalytic activities (yields up to 96.7%). Additionally, the functionalized hybrid polyoxovanadates catalyst can be reused without losing activities after three runs cycle.

Catalyzed Oxidation

With the increasing interest in polyoxometalates (POMs) materials over the past few decades, scientific researchers have focused their attention on the fruitful utilization of POMs hybrids as efficient catalysts in many organic reactions. In this paper, dipyridine amine (dpa) organic ligand hybrid polyoxomolybdate material was solvothermally synthesized and structurally identified by elemental analysis, X-ray diffraction and infrared spectrum. Structural refinement of the hybrid polyoxomolybdate compound 1 with general formula [Hdpa]4Mo8O26 · 2DMF (DMF = N,N-dimethylformamide) shows that compound 1 presents in the space group P-1 with triclinic system, and is built up from a well-known β-[Mo8O26]4– anionic cluster, four free protonated dpa cations and two free DMF molecules. Remarkably, the β-Mo8O26-based hybrid material was further applied as the catalyst in the conversion of sulfides utilizing hydrogen peroxide (30%) as green terminal oxidant and exhibited efficient catalytic activities for selective oxidation of sulfides.

The catalytic activities of CeO2-MnOx composite oxides synthesized through oxalate method were researched. The results exhibited that the catalytic properties of CeO2-MnOx composite oxides were higher than pure CeO2 or MnOx. When the Ceat/Mnat ratio was 3:7, the catalytic activity reached the best. In addition, the activities of CeO2-MnOx synthesized through different routes over benzene oxidation were also comparative researched. The result indicated that the catalytic property of sample prepared by oxalate method was better than others, which maybe closely related with their meso-structures. Meanwhile, the effects of synergistic interaction and oxygen species in the samples on the catalytic ability can’t be ignored.
