CATALYST AND FLUID PURIFIER

摘要

PROBLEM TO BE SOLVED: To provide a fluid purifier using a catalyst capable of suppressing deterioration in catalytic ability due to clogging of tubular spaces caused by adhesion of inorganic solid substances.SOLUTION: There is provided a catalyst 25 which is used to accelerate an oxidative decomposition reaction of organic substances contained in a fluid to be purified in a reaction tank in a fluid purifier and accelerates oxidative decomposition of organic substances in fluid which are received in each of a plurality of tubular spaces 25a in a parallel tube structure in which the plurality of tubular spaces 25 are arranged in a direction orthogonal to the longitudinal direction, wherein through-holes 25c for communicating the mutually adjacent tubular spaces 25a are provided on each of a plurality of partition walls 25b for partitioning between the mutually adjacent tubular spaces 25a.
