Pt‐Anchored‐Zirconium Phosphate Nanoplates as High‐Durable Carbon‐Free Oxygen Reduction Reaction Electrocatalyst for PEM Fuel Cell Applications

Abstract: Commercially available platinum‐supported carbon (Pt/C) catalysts are the most widely used oxygen reduction reaction (ORR) electrocatalysts in polymer electrolyte membrane fuel cells (PEMFCs). However, inadequate active triple‐phase boundary formation and carbon oxidation in Pt/C during PEMFC operation shorten its lifetime and efficiency. In this direction, a new class of carbon‐free electrocatalysts for ORR is prepared by dispersing Pt nanoparticles on ZrP (Zirconium phosphates) nanoplates. In one case (ZrP@P… Show more

“…Furthermore, the protons and oxygen have limited access to the Pt particles inside the micropores leading to high polarization losses at high current densities . As a practical approach to address the carbon corrosion and micropore-induced limitations, metal oxides, such as RuO 2 , TiO 2 , WO 3 , and SiO 2 , have been used in place of the carbon support to deposit the Pt nanoparticles. , …”
