Conducting cycle tests and measuring reaction products! Introducing the materials used and test results.

We will introduce the performance test of alcohol gas decomposition using the photocatalyst "Titanistar." 【Decomposition Performance of Various Alcohol Gases and Cycle Tests】 Base Material: Titanistar MI-W, Titanium Plate 100mm x 100mm, and Titanium Mesh 100mm x 100mm Gas Used: Ethyl Alcohol and Isopropyl Gas, each at 100ppm In a 550ml quartz container, MI-W plate material and EtOH were sealed and exposed to ultraviolet light (1mw/cm²) for 1 hour, measuring the concentration every hour. After the concentration decreased to a certain level, a cycle test was conducted by sealing new gas to evaluate the durability of the photocatalytic film. Tests were also conducted using titanium mesh, IPA plates, and IPA mesh in the same manner. As a result, it was confirmed that various alcohols were decomposed, and the cycle test with new gas sealing also showed no significant difference in decomposition. For the titanium plate and mesh, it was confirmed that the mesh material with a higher surface area decomposed more quickly. *For more details, please download the PDF or feel free to contact us.

basic information

What is the photocatalyst "Titanistar"? It is not a coating-type photocatalyst, nor does it use any of the raw materials typically employed in such products. By simply performing surface oxidation treatment on titanium within pure titanium metal, it generates a titanium dioxide photocatalyst film on the surface of pure titanium. This film contains no impurities and is generated without any interface with pure titanium. It is characterized by high photocatalytic ability and a highly durable film. What the photocatalyst "Titanistar" can solve: - Water purification and water quality improvement; however, it is not suitable for purifying highly contaminated water. - Gas purification and air cleaning. - Measures against general bacteria and various viruses. Measurement of ethyl alcohol gas decomposition and reaction products: We conducted measurements of the decomposition of EtOH gas and the concentration of reaction products in carbon dioxide. It was revealed that, along with the oxidative decomposition, there was a decrease in gas concentration and a simultaneous increase in the concentration of reaction products. *For more details, please download the PDF or feel free to contact us.*
