Photocatalytic filter with porous metal substrate and fixed photocatalyst
The patent application (Publication Number: US20230372919A1) discloses a novel photocatalytic filter designed for air purification applications. The filter comprises a porous metal filter substrate with a photocatalyst fixed onto it. The thickness of the porous metal and the average cell number per inch determine the effectiveness of the filter, with the product of these two parameters falling within a specific range for optimal performance.
The porous metal used in the filter is selected from materials like nickel, silver, copper, aluminum, nickel-chrome, nickel-tin, and nickel-iron. Nickel is specifically mentioned as a material present in the porous metal. The filter also has low transmittance for ultraviolet light and utilizes titanium oxide as the photocatalyst with a specific particle size range. The support amount of the photocatalyst on the filter substrate is also defined. Additionally, the filter is designed in a flat planar shape for practical use. The patent application also includes a deodorizing apparatus incorporating this photocatalytic filter, highlighting its potential application in air purification systems.
