Опубликована: Март 28, 2025

A Pd-decorated V2O5/porous silicon (Pd-V2O5/PSi) composite was synthesized via magnetron sputtering for enhanced NO2 gas sensing. The material’s morphology and composition were systematically characterized, its sensing performance evaluated through comprehensive experimental measurements first-principles calculations. decoration of Pd nanoparticles significantly improved the capabilities V2O5/PSi composite, particularly enhancing sensitivity response/recovery characteristics. Experimental results revealed a 3.1-fold increase in response to specific concentrations (ppm level) compared undecorated sensor. exhibited rapid at room temperature with excellent selectivity, reproducibility, long-term stability. First-principles calculations elucidated structural, electronic, adsorption properties Pd-V2O5/PSi uncovering mechanism environments. This combined theoretical study provides valuable insights developing advanced sensors lays foundation optimizing metal oxide-based materials.
