Facile synthesis of MOF-5 confined in SBA-15 hybrid material with enhanced hydrostability

摘要

A MOF-5 [Zn_4O(BDC)_3; BDC = 1,4-benzenedicarboxylate]@SBA-15 hybrid material has been prepared by using SBA-15 as a matrix. This hybrid material exhibits improved hydrostability under ambient conditions and unique gas adsorption behavior compared with pristine MOF-5. Metal-organic frameworks (MOFs) are promising materials for applications in gas storage, catalysis, and separation due to their tunable pore size and high surface area. Among reported MOFs, MOF-5 is one of the benchmark materials that have been extensively studied. It is derived from basic zinc acetate units [(Zn_4O)(CH_3COO)_6] bridged by 1,4-benzenedicarboxylate (1,4-BDC) linkers and features high thermal stability and gas adsorption capacity.
