Synergistically enhanced oxygen reduction reaction through the optimal adsorption of oxygen molecules in a sub-5 nm-sized Pt0.4Zn0.1Ni0.5 ternary ensemble alloy catalyst

Synergistically enhanced oxygen reduction reaction through the optimal adsorption of oxygen molecules in a sub-5 nm-sized Pt0.4Zn0.1Ni0.5 ternary ensemble alloy catalyst

This study aimed to develop an oxygen reduction reaction (ORR) catalyst with high O2 adsorption capacity by introducing Zn into a PtNi alloy. The three-way alloy was synthesized by incorporating Ni and Zn, which are compatible with hydrogen and oxygen, and significantly reducing the Pt component to
