発明の名称 (英語) Honeycomb structure and manufacturing method thereof, and air cleaner and water purifier containing the honeycomb structure
発明の概要(英語) A composite honeycomb structure in which the honeycomb structure is highly functionalized and adapted to have catalytic function, considering pressure loss is provided.
A honeycomb structure having average pore diameter of 5 to 200 μm and specific surface area of 100 to 1500 m2/g is provided.
Further, a translucent honeycomb structure and a photocatalyst-carrying translucent honeycomb structure having a photocatalyst carried on a surface of the translucent honeycomb structure and/or contained in the translucent honeycomb structure are provided.
Further, an air cleaner and a water purifier using the honeycomb structure and the photocatalyst-carrying translucent honeycomb structure are provided.
