Representative work: Urea oxidation reaction (UOR) has been proposed to replace the formidable oxygen evolution reaction (OER) to reduce the energy consumption for producing hydrogen from electrolysis of water owing to its much lower thermodynamic oxidation potential compared to that of the OER. Therefore, exploring a highly efficient and stable hydrogen evolution and urea electrooxidation bifunctional catalyst is the key to achieve economical and efficient hydrogen production. In this paper, we report a heterostructured sulfide/phosphide catalyst (Ni3S2–Ni3P/NF) synthesized via one-step thermal treatment of Ni(OH)2/NF, which allows the simultaneous occurrence of phosphorization and sulfuration. The obtained Ni3 Pt-based catalysts are the most promising catalysts for proton exchange membrane fuel cells (PEMFCs) but still suffer from sluggish kinetics for the oxygen reduction reaction (ORR). Alloying Pt with transition-metal (M) elements is an efficient approach to modulate the electronic structure of Pt-based catalysts and improve the catalytic performance for the ORR. However, owing to the distinguishing surface state caused by different synthetic approaches, there still exist contradictory views about the relationship between the structure of Pt-based alloys and the catalytic performance for the ORR. In this work, PtCo alloys with a similar surface state but diverse structures and compositions are
