Surface modification with phosphoric acid of SiO2/Nb2O5 prepared by the sol-gel method : structural-textural and acid sites studies and an ion exchange model
In this work, the structural and textural properties of the SiO2/Nb2O5 system prepared by the sol-gel method and then modified by phosphoric acid were studied. The different materials were prepared, with three different mol % Nb2O5 (2.5, 5.0, and 7.5 mol %), and calcined in the temperature range of...
