Investigators from University of Jinan Have Reported New Data on Chalcogens (A Hierarchical Nanoporous PtCu Alloy as an Oxygen-Reduction Reaction Electrocatalyst with High Activity and Durability)

By a News Reporter-Staff News Editor at Life Science Weekly -- Data detailed on Chalcogens have been presented. According to news originating from Jinan, People's Republic of China, by NewsRx correspondents, research stated, "A hierarchical nanoporous (HNP) PtCu alloy was successfully fabricated by two-step dealloying of a well-designed PtCuAl precursor alloy combined with an annealing operation. The asmade PtCu alloy has an interconnected hierarchical network architecture with controllable bimodal ligament/pore distributions obtained by adjusting the annealing temperature and the redealloying time."

Our news journalists obtained a quote from the research from the University of Jinan, "HNP-PtCu exhibits superior specific and mass activities for the oxygen-reduction reaction (ORR) compared with single-modal nanoporous PtCu and commercial Pt/C catalysts. More importantly, the HNP-PtCu alloy shows much higher structure stability with less loss of the electrochemical surface area of Pt and ORR activity upon long-term potential scans in acid solution."

According to the news editors, the research concluded: "The excellent electrocatalytic performance for ORR makes the HNP-PtCu alloy attractive as efficient cathode electrocatalysts in fuel-cell-related technologies."
