Area of Science:

  • Materials Science
  • Catalysis
  • Nanotechnology

Background:

  • Developing efficient catalysts for photocatalysis is crucial.
  • Incorporating noble metals into metal-organic frameworks (MOFs) presents challenges.
  • Achieving stable dispersion of metal atoms within MOFs is difficult.

Purpose of the Study:

  • To develop a novel method for dispersing platinum (Pt) atoms within the UiO-66 MOF.
  • To investigate the photocatalytic efficiency of the resulting Pt@UiO-66 composite for hydrogen evolution.
  • To understand the structural and electronic properties influencing the enhanced catalytic activity.

Main Methods:

  • Utilized supercritical carbon dioxide (SC CO2) as a directing agent for Pt atom impregnation.
  • Synthesized Pt@UiO-66 composites.
  • Performed experimental characterization and theoretical calculations to analyze the structure.
  • Evaluated photocatalytic hydrogen evolution under visible-light irradiation.

Main Results:

  • Achieved stable encapsulation of atomically dispersed Pt within the UiO-66 framework.
  • Demonstrated rapid transfer of photogenerated electrons between Pt and UiO-66 components.
  • Obtained an exceptionally high hydrogen production rate of 3871.4 μmol h⁻¹ g⁻¹ for Pt@UiO-66 under visible light.
  • Observed a nearly 50-fold increase in H2 evolution compared to pure UiO-66.

Conclusions:

  • The SC CO2-directed strategy is effective for creating highly dispersed noble metal catalysts within MOFs.
  • Pt@UiO-66 composites show remarkable photocatalytic performance for hydrogen evolution.
  • This work provides a new pathway for designing advanced MOF-based photocatalysts.
