摘要：A series of new metal-organic frameworks (MOFs) composed of a transition-metal organic acid salt and 2, 5-bis(3-pyridyl)-3,4-diaza-2,4-hexadiene (3-bpdh) was prepared via diffusion in a H2O-MeOH solvent system. The results illustrated that MOFs self-assembly should be achieved by metal-ion potential and building blocks. The loading of MOF microcrystals with titanium dioxide resulted in the composite photocatalyst TiO2@ZnMOF, which exhibited excellent photodegradation (64%) of the dye methyl blue. Importantly, this approach provides an innovative way of enhancing the photocatalytic effect of MOFs with potential applications as a catalyst support. (C) 2016 Elsevier B.V. All rights reserved.
