(57) [Summary] [Object] To provide a porous adsorbent capable of adsorbing both a sulfur (S) odor component and a nitrogen (N) odor component with high performance. [Structure] An inorganic porous material having an inorganic pillar material disposed between layers of a swellable layered compound and an adsorbent. The inorganic pillar material is alumina, silica-alumina composite oxide, silica-titania composite oxide, silica-zirconia, iron oxide, It is at least one selected from the group consisting of nickel oxide, cobalt oxide, manganese oxide, vanadium oxide, and copper oxide. The inorganic pillar material is a photocatalyst. Photocatalyst is titania, strontium titanate, zirconia, It is at least one selected from the group consisting of zinc oxide and tin oxide. The adsorbent is at least one selected from the group consisting of activated carbon, activated carbon fiber, charcoal, silica gel, activated alumina, zeolite, zirconium phosphate and zinc oxide. |
