Area of Science:

  • Materials Science
  • Nanotechnology
  • Electrochemistry

Background:

  • Molybdenum disulfide (MoS2) nanosheets are promising nanomaterials with unique electronic properties.
  • Achieving stable dispersions and controlled assembly of MoS2 nanosheets in aqueous environments remains a challenge.
  • Functionalization strategies are needed to enhance the performance of MoS2-based materials for sensing applications.

Purpose of the Study:

  • To synthesize polyelectrolyte-functionalized MoS2 nanosheets with improved water dispersibility and stability.
  • To fabricate layer-by-layer (LBL) self-assembled films using these modified MoS2 nanosheets.
  • To evaluate the electrocatalytic activity of the MoS2-based films for hydrogen peroxide (H2O2) detection.

Main Methods:

  • In situ polymerization of MoS2 nanosheets with poly(acrylic acid) and poly(acrylamide).
  • Layer-by-layer (LBL) self-assembly technique to create uniform MoS2-based films on various substrates (quartz, silicon, ITO).
  • Electrochemical characterization of the modified electrodes to assess electrocatalytic activity towards H2O2.

Main Results:

  • Successfully obtained few-layered polyelectrolyte-functionalized MoS2 nanosheets exhibiting excellent dispersibility and stability in water.
  • Fabricated uniform MoS2 nanosheet-based LBL films with precisely controlled layer thickness.
  • Demonstrated enhanced electrocatalytic activity for H2O2 using the polyelectrolyte-functionalized MoS2 nanosheet assembled LBL film-modified electrodes.

Conclusions:

  • Polyelectrolyte functionalization provides an effective route to stabilize MoS2 nanosheets in water and enable LBL assembly.
  • The developed MoS2-based LBL films exhibit superior electrocatalytic performance for H2O2.
  • These findings highlight the potential of functionalized MoS2 nanosheets for constructing efficient sensors and advanced biosensing systems.
