Hierarchical macro-mesoporous Mo/Al2O3 catalysts prepared by dual-template method for oxidative desulfurization
A series of Al 2 O 3 materials with hierarchical macro-mesoporous structure were synthesized by a dual-template method, using surfactant Pluronic P123 and polystyene (PS) spheres as templates. Then, the catalysts Mo/Al 2 O 3 were prepared by the incipient wetness impregnation method. The samples wer...
