Area of Science:

  • Materials Science
  • Nanotechnology
  • Chemical Engineering

Background:

  • Hydrogen gas detection is crucial for safety and industrial processes.
  • Developing sensitive and reliable hydrogen sensors remains an active research area.
  • Metal oxide semiconductors, like zinc oxide (ZnO), show promise for gas sensing applications.

Purpose of the Study:

  • To develop a novel approach for hydrogen gas detection using manganese (Mn) implanted ZnO nanowires.

Main Methods:

  • ZnO nanowires were fabricated on ITO-coated glass using chemical spray pyrolysis deposition.
  • Manganese (Mn) was implanted into the ZnO nanowires.
  • Structural, optical, and morphological properties were analyzed using X-ray diffraction (XRD), photoluminescence (PL), and field-emission scanning electron microscopy (FE-SEM).
  • Energy-dispersive X-ray (EDX) spectroscopy confirmed material composition.
  • Hydrogen sensing performance was evaluated.

Main Results:

  • XRD confirmed polycrystalline hexagonal wurtzite ZnO structure with no impurities, and peak shifts indicated successful Mn incorporation.
  • Optical band gap decreased with increasing Mn concentration.
  • PL spectra showed high crystalline quality of ZnO nanowires.
  • FE-SEM images revealed perfectly aligned nanowires.
  • Hydrogen gas response of the Mn-doped ZnO nanowire sensor increased by over an order of magnitude with higher Mn doping.

Conclusions:

  • Mn-implanted ZnO nanowires exhibit enhanced hydrogen sensing properties.
  • The developed sensors are low-cost and easy to fabricate.
  • These materials show significant potential for practical hydrogen gas detection applications.
