摘要
Replacing the metal ions (or metal clusters) in routine MOFs with size-matched polyoxoanions to construct POM-based MOF materials (POMOF) combining well-defined crystalline structures, high surface area, regular and tunable cavities is the great challenge in the current POM chemistry area. In this work, we report a 2-fold interpenetrated porous POMOF, [TBA](6)[H3PMo12O40](2)[Zn-8(BTB)(2)]center dot(similar to 35H(2)O), which exhibits effective catalytic activity towards bromate reduction, using the methodology of extension for the reduced transition-metal-grafted epsilon-Keggin polyoxoanions with an expanded tripodal bridging ligand of H3BTB. The simultaneous TGA/DSC-MS technique was applied in this work to identify the evolved gases and was proved to be an effective method for analysing the decomposition process.
