Effect of Metal Site Mobility of Single-Atom Catalyst on Photocatalytic Water Oxidation

The Journal of Physical Chemistry Letters, Journal Year: 2025, Volume and Issue: 16(9), P. 2166 - 2174

Published: Feb. 20, 2025

Understanding the impact of catalytic site diffusion on photocatalytic performance is crucial to rational design water oxidation photocatalysts. In this study, we combined ab initio nonadiabatic molecular dynamics (NAMD) with density functional theory (DFT) calculations investigate single-atom transition metals (Ni, Pd) loaded HfS2 and their effects oxidation. Transition state indicated that barriers (0.58 eV) enable possibility between most stable HS metastable HHf for Pd/1T-HfS2. Moreover, electronic structure simulations reveal distinct properties Pd/1T-HfS2:Pd adsorption at generate a deep defect (∼0.5 eV above valence band maximum (VBM)), while introduces shallow near VBM (∼0.2 VBM). Compared pristine 1T-HfS2 (6.2 ns), electron-hole recombination time extends 7 ns Pd(HS)/1T-HfS2 but decreases 1.7 Pd(HHf)/1T-HfS2, driven by position Pd-induced states. Thermodynamically, Pd(HHf)/1T-HfS2 show pronounced difference, approximately 0.08 V in limiting potential. Generally, study enhances understanding dynamic catalysts.
