Area of Science:

  • Materials Science
  • Catalysis
  • Renewable Energy

Background:

  • Environmentally harmful fuels necessitate sustainable alternatives.
  • Green hydrogen is a promising clean energy solution.
  • Molybdenum disulfide (MoS2) is explored as a catalyst for water splitting.

Purpose of the Study:

  • To develop an effective few-layer MoS2 catalyst for overall water splitting.
  • To investigate the role of surfactants in catalyst performance.
  • To evaluate the potential of MoS2-SDS as a green hydrogen production catalyst.

Main Methods:

  • Two-step synthesis: liquid-phase exfoliation with surfactants (SDS, CTAB) followed by hydrothermal reaction.
  • Characterization of MoS2 morphology, structure, and bandgap.
  • Electrocatalytic evaluation of hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) performance.
  • Long-term stability testing for overall water splitting.

Main Results:

  • Few-layer MoS2-SDS exhibited reduced layers and increased bandgap.
  • MoS2-SDS demonstrated excellent HER (η10 = 125 mV) and OER (η10 = 213 mV) performance.
  • High surface area, low charge transfer resistance, and >20 h durability were observed.
  • Overall water splitting achieved >90% Faradaic efficiency and 60% energy conversion efficiency over 110 h.

Conclusions:

  • Few-layer MoS2-SDS is a highly effective catalyst for electrocatalytic alkaline water splitting.
  • This catalyst presents a viable, sustainable alternative to noble metal catalysts for green hydrogen production.
  • The developed MoS2-SDS catalyst holds significant promise for practical applications in renewable energy.
