FeP as cocatalyst for ultra-low Pt oxygen reduction reaction catalyst.

The preparation of low Pt catalysts for oxygen reduction reaction (ORR) has been the focus research in fuel cell. Here, Pt&FeP@NC with ultra-low Pt loading (∼2 wt% Pt, one tenth of the commercial 20 wt% Pt/C) is prepared by introducing FeP cocatalyst into Pt-based catalyst through a simple two-step pyrolysis method. Pt&FeP@NC shows excellent ORR electrocatalytic performance in 0.

Advances of Vanadium-based Cathodes forAqueous Zinc Ion Batteries.

Aqueous zinc-ion batteries (AZIBs) are promising for energy storage due to their high safety, low cost, and environmental friendliness. Vanadium-based materials, including vanadium oxides, vanadium sulfides, vanadate, and vanadium carbon composites, have gained attention for their diverse crystal structures, multiple oxidation states, and high theoretical capacities. This review summarizes recent advances in vanadium-based cathodes, focusing on structural design and modification strategies, such as amorphous structures, defect engineering, conductive carbon matrices, and cation pre-intercalation to enhance Zn storage.
