Conducting demonstration tests of photocatalytic capabilities! Introducing oxidation decomposition ability and superhydrophilicity.
In general, photocatalysts have the ability to oxidatively decompose organic substances and harmful materials, rendering them harmless. It is said that hydrophilicity occurs on the surface of the photocatalyst in an excited state. We conducted verification tests on these photocatalytic capabilities.
- Oxidative Decomposition Ability
We treated non-woven pure titanium, a substrate made of pure titanium cut into 100mm squares, with gas-type Titanister. After sealing it in a Tedlar bag with approximately 250ppm of acetaldehyde gas and reaching adsorption equilibrium, we irradiated it from above with a 1mW/cm² BLB lamp, measuring the concentration of acetaldehyde gas and the concentration of the reaction product, carbon dioxide, at regular intervals.
As the concentration of acetaldehyde gas decreased due to Titanister, the concentration of carbon dioxide, the reaction product, increased. Ultimately, it was found that approximately 230ppm of acetaldehyde gas was almost completely decomposed, and a quantity of reaction replicable substances equivalent to twice the concentration of acetaldehyde gas was produced.
