Pore-size Control Method of Mesoporous Magnesium Aluminate using Defect Spinel Formation

摘要

The present invention relates to a method for controlling the mesoporous size of magnesium aluminate, the method for controlling the pore size according to the present invention comprises: a) an aluminum source using evaporative induction self-assembly; Magnesium source; And a structure-forming agent which is a nonionic surfactant; preparing an organic-inorganic complex from the precursor solution containing; And b) calcining the prepared organic-inorganic composite to prepare magnesium aluminate; and controlling the molar ratio of Al:Mg contained in the precursor solution in the step a) to produce in step b) It controls the meso pore size of magnesium aluminate.
