Catalyst-supporting porous membrane, catalyst member, air cleaning device, and method for producing catalyst-supporting porous membrane

摘要

A catalyst-supporting porous film includes: a resin layer; and catalyst particles dispersed in the resin layer. The catalyst particles are unevenly distributed so as to be present at a surface of the resin layer. Preferably, the catalyst-supporting porous film includes a porous section and a supporting section for supporting the porous section. The number of catalyst particles per unit volume in the porous section is greater than the number of catalyst particles per unit volume in the supporting section. Thus, a catalyst-supporting porous film which has a high catalytic effect can be provided.

主权项

1. A catalyst-supporting porous film, comprising:
an exposed surface having a moth-eye structure or inverted moth-eye structure; a resin layer; a plurality of through holes arranged in a matrix; and catalyst particles dispersed in the resin layer, wherein the exposed surface includes the catalyst particles unevenly distributed such that substantially all of a surface of the resin layer is covered with the catalyst particles.
