MOF-5 is a representative Zn-based MOF, in which inorganic [Zn4O]6+ clusters combine with organic benzene-1,4-dicarboxylate (BDC) linkers to form a porous Zn4O(BDC)3 framework with a distance of 12.94 � between the centers of adjacent clusters and an interconnected pore diameter of 8 �. In this work, in-situ FT-IR was employed to reveal the effect of hydrogen on thermal decomposition of MOF-5, which would be important for the application of MOF-5 as hydrogenation catalysts. It was found that the decomposition temperature of MOF-5 is 50oC lower in 3MPa H2 than in vacuum. This happened because the C-H bond formation of MOF-5 in H2 partially destroyed the MOF-5 structures. Furthermore, this was further confirmed by deuterium effect.
