A new way of assessing the interaction of a metallic phase precursor with a modified oxide support substrate as a source of information for predicting metal dispersion

A new way of assessing the interaction of a metallic phase precursor with a modified oxide support substrate as a source of information for predicting metal dispersion

Well-dispersed nanosized clusters of metallic platinum were obtained by decomposition of ethylenediamine complexes immobilized on amorphous silica surfaces. Samples before reduction were obtained by potentiometric titration in a heterogeneous liquid/solid system in different pH ranges. The proposed...
