A purification and catalyst system using a new hollow structure that can be replaced with a honeycomb type is provided. SOLUTION: A hollow structure for purification and catalysis comprising a hollow body made of ceramics or a refractory metal as a carrier or filter part, wherein the carrier or filter part is an assembly of hollow bodies of a predetermined size. A purification structure, a catalyst structure, and the hollow structure are formed in a container or a wall, and the hollow structure has a through-hole serving as a gas passage. A purification and catalyst system characterized in that the hollow body is fixed so as not to move by fixing means arranged at a predetermined position inside the pipe and having sufficient openings for both ends of the gas to pass therethrough. [Effects] A variety of unit shapes can be accommodated, and even if hollow bodies are rubbed together, the catalyst does not fall off, and a new purification and catalyst system in which purification and catalytic reaction proceed efficiently can be provided.
