Tailoring of highly porous SnO₂ and SnO₂-Pd thin films

Utilizing glancing angle deposition, we control the geometry of porous tin oxide films. The nanorod-like structure of the deposited films can be tuned to form intricate patterns, such as spirals or zig-zags. We analyze each pattern via microscopy in combination with computer modeling and determine the film with the highest surface area to material ratio. The film is then further characterized with respect to the potential application in gas sensing and catalysis, focusing on temperature stability and metal loading. The results are available in a new Materials Chemistry and Physics paper.
