Alcohol induced ultra-fine dispersion of Pt on tuned morphologies of CeO2 for CO oxidation
(Elsevier Science, 2013-02)
Controlling the structures of supports and supported phases is important for catalytic applications where synergic effects can play a main role. In this context, we present versatile methods for suitable microstructurization ...
Characterization of CeO2 doped MgAl2O4 prepared by the chelating agents-assisted impregnation method
(Sociedade Brasileira de Química, 2018-08)
MgAl2O4 spinel employed as support of reforming catalysts was doped by CeO2. The samples were prepared by wet impregnation from aqueous solutions of cerium nitrate, with and without chelating agents. The chelating agents ...
