Abstract
Photocatalysts, such as titanium dioxide, have a strong tendency to crack when exposed to organic substances. Titanium dioxide is frequently applied in the process of deodorization. We developed a deodorization device using a silica gel coated with titanium dioxide. The device was confirmed to be effective as a deodorizer of the smell of ethanol and related odors. The device can be used continuously and maintenance-free due to the photocatalytic reaction. The device must be filled with over 100g of the photocatalyst silica gel. We confirmed that the liquid deodorizer cyclodextrin (CD) in the atomization space could be decomposed.
