| 英文摘要 | Constructing atomically dispersed platinum (pt) electrocatalysts is essential to build high-performance and cost-effective electrochemical water-splitting systems. we present a novel strategy to realize the traction and stabilization of isolated pt atoms in the nitrogen-containing porous carbon matrix (pt@pcm). in comparison with the commercial pt/c catalyst (20 weight %), the as-prepared pt@pcm catalyst exhibits significantly boosted mass activity (up to 25 times) for hydrogen evolution reaction. results of extended x-ray absorption fine structure investigation and density functional theory calculation suggest that the active sites are associated with the lattice-confined pt centers and the activated carbon (c)/nitrogen (n) atoms at the adjacency of the isolated pt centers. this strategy may provide insights into constructing highly efficient single-atom catalysts for different energy-related applications. |
