PROBLEM TO BE SOLVED: To obtain a photocatalyst deodorizing device with certain resolution capability, which is not influenced by the enviromental pH of substrate gas.SOLUTION: In a photocatalyst deodorizing device 1, substrates provided with ventilating holes are arranged in parallel LEDs are mounted on at least one substrate between the two sheets of substrates a photocatalyst sheet composed of a glass fiber textile supporting photocatalyst particles and a frame supporting the textile is arranged between the two sheets of substrates photocatalyst sheets 61 and 62 and the two sheets of substrates 5 and 7 are fixed to a casing 8 and the light emitting face of an LED light source 3 and the photocatalyst sheets 61 and 62 are arranged in parallel so that the air sent in from the ventilating holes may pass the photocatalyst sheets 61 and 62. The photocatalyst sheet 61 supporting a titania photocatalyst particle 61B on the glass fiber textile 61A is arranged on the gas introduction side In of the photocatalyst deodorizing device, and also a photocatalyst sheet 62 supporting photocatalyst particles 62B, the main ingredient of which is a tungsten oxide, in the glass fiber textile 62A, is arranged on the gas discharge side Out of the photocatalyst deodorizing device 1.COPYRIGHT: (C)2012,JPO&INPIT【課題】基質ガスの環境pHに左右されない、一定の分解能力の光触媒脱臭装置を得る。【解決手段】通風孔を設けた基板を平行に配置し、2枚の基板の内、少なくとも1枚の基板にLEDを実装し、2枚の基板間に、光触媒粒子が担持されたガラス繊維織物及び当該織物を支持するフレームから構成される光触媒シートを配置し、光触媒シート61,62と2枚の基板5,7を筺体8に固定し、LED光源3の発光面と光触媒シート61,62とを平行に配置して、通風孔4から送入された空気が光触媒シート61,62を通過するようにした光触媒脱臭装置1であって、酸化チタン光触媒微粒子61Bをガラス繊維織物61Aに担持した光触媒シート61を当該光触媒脱臭装置のガス導入側Inに、また酸化タングステンを主成分とする光触媒微粒子62Bをガラス繊維織物62Aに担持した光触媒シート62を当該光触媒脱臭装置1のガス排出側Outに配置したもの。【選択図】 図2
