All-Metal Mesoporous Nanocolloids: Solution-Phase Synthesis of Core-Shell Pd@Pt Nanoparticles with a Designed Concave Surface

Colloidal Pd@Pt nanoparticles with uniform mesopores can be synthesized in one step by a facile solution‐phase method involving slow reduction of metal species in strong acidic media. In this system, F127 micelles can directly act as a template to form the mesopores in the product, and the greater r...

Zusammenfassung:Colloidal Pd@Pt nanoparticles with uniform mesopores can be synthesized in one step by a facile solution‐phase method involving slow reduction of metal species in strong acidic media. In this system, F127 micelles can directly act as a template to form the mesopores in the product, and the greater reducibility of the Pd species leads to the desired core–shell Pd@Pt nanocolloids.
