Substitutional Platinum‐Phosphorus Solid Solution by Phosphidation of Worm‐Like Pt Nanoparticles Using Tri‐n‐octylphosphine
Source abstract
Abstract
Abstract Herein, the investigations into the phosphidation of platinum (Pt) nanoparticles are reported using tri‐n‐octylphosphine (TOP) at elevated temperature in an organic solvent, and identify a unique phenomenon not addressed before: The phosphorus (P) atoms can replace partial Pt atoms from their lattice points to form a substitutional Pt‐P solid solution. The rationality is authenticated for forming substitutional Pt–P solid solution via P doping by various characterizations and density functional theory (DFT) calculations, both of which suggests that the maximum P content in the Pt–P solid solution is approximately ≈10% for maintaining the stability of the face‐centered cubic crystal structure.
