The study discusses a new method for creating ultraporous titanium dioxide thin films using plasma deposition and etching, which can be done at room or mild temperatures.
These films have over 85% porosity, maintain their structure even after high-temperature annealing, and exhibit unique properties like being antireflective and superhydrophilic under UV light.
The resulting porous films can be used as electrodes in perovskite solar cells and have potential applications in various fields such as energy storage, photonics, and controlled wetting due to their scalable and solvent-free synthesis process.
The study utilized various advanced techniques to explore how phenylacetylene and chlorobenzene interact with a silver surface (Ag(100)) during specific chemical reactions.
It was found that these molecules can undergo important reactions, even though chlorobenzene is typically considered unreactive; both adsorbates displayed a flat orientation and were primarily held to the surface by weak dispersion forces.
The observed formation of islands on the surface may limit chemical reactions, suggesting that the area where these islands meet could play a critical role in reaction activity, and these findings could inform the design of better catalytic systems.
