Atomic layer deposition (ALD) precisely coats surfaces, enabling advanced catalyst design. This technique tailors nanoporous materials for enhanced photocatalytic and acid catalytic activities.

Area of Science:

  • Materials Science
  • Chemical Engineering
  • Nanotechnology

Background:

  • Atomic layer deposition (ALD) is a surface-controlled thin-film deposition technique.
  • ALD's self-limiting reactions ensure precise thickness control and conformality, even on complex 3D structures.
  • While established in microelectronics, ALD's conformality is valuable for functionalizing porous materials.

Purpose of the Study:

  • To review the application of Atomic layer deposition (ALD) in catalyst design.
  • To highlight ALD's potential for tailoring nanoporous materials for catalytic applications.
  • To discuss specific examples of ALD in creating catalytic sites.

Main Methods:

  • Utilizing ALD for conformal coating of nanoporous substrates.
  • Depositing titanium dioxide (TiO2) on nanoporous films to investigate photocatalytic activity.
