Exploration of Hydrogen Storage Exhibited by Rh‐Decorated Pristine and Defective Graphenes: A First‐Principles Study

Energy Storage, Journal Year: 2024, Volume and Issue: 6(8)

Published: Nov. 17, 2024

ABSTRACT We utilized density functional theory (DFT) to ascertain the storage of hydrogen in Rh‐decorated pristine (PG) and defective graphenes, primarily graphitic‐N (GNG) pyridinic‐N (PNG). The binding energy a single Rh atom on PG, GNG, PNG was found be −1.87, −2.18, −4.01 eV, respectively. PG exhibits weak adsorption molecules (−0.06 eV/H 2 ). On other hand, graphenes show incredibly higher energy. As per latest guidelines U.S. Department Energy (DOE), GNG (Rh@GNG) is best material out three systems investigated here. atom‐decorated adsorbs up 4H . Uniform decoration graphene surfaces with atoms necessary improve performance. Both sides are decorated 8Rh atoms, which can adsorb 24H molecules, an average −0.33 mechanism H host system has been explored based DFT‐evaluated deformation charge density, partial states (PDOS), non‐covalent interaction (NCI) plots. For better understanding process, diffusion barrier metal computed using climbing image nudged elastic band (CI‐NEB) method, thermal stability evaluated through ab initio molecular dynamics (AIMD) simulations.
