    Researchers developed a novel epitaxy method to create vertically aligned nanopores in mesoporous inorganic thin films. This technique enables improved diffusion for applications requiring pore access in self-assembled materials.

    Area of Science:

    • Materials Science
    • Nanotechnology
    • Inorganic Chemistry

    Background:

    • Polymer- and surfactant-templated mesoporous inorganic materials offer tunable nanoscale architectures and low-cost processing.
    • Conventional hexagonal mesoporous films exhibit in-plane pores, limiting diffusion-based applications.
    • Existing methods often compromise the processing advantages of self-assembled systems.

    Discussion:

    • Nanometre-scale epitaxy on patterned substrates enables the formation of vertically oriented pores in mesoporous honeycomb films.
    • Utilizing the surface of cubic mesoporous films as a pattern preserves the benefits of self-assembly.
    • Achieving vertical pore orientation requires precise lattice matching between hexagonal and cubic mesoporous films, attainable through mixed templates or selective pore swelling.
