Description
本発明は、液相中の過酸化水素を水と酸素に分解するための過酸化水素分解触媒であって、気孔を有する無機酸化物材料からなる担体と、担体に担持されたＰｔ、Ｐｄ、Ｉｒ、Ｒｕ、Ｒｈ及びＯｓからなる群から選ばれる少なくとも１種の元素を含む活性金属とを備え、担体の表面近傍において活性金属が担持されている層の厚さが０．０１〜０．２５ｍｍである触媒を提供する。ここでいう「担体の表面近傍において活性金属が担持されている層」とは、担体の表面から２．０ｍｍ以内の領域（以下、この領域を「担体の表面近傍」という。）において、担体に担持されている活性金属の総含有量に対する９割合以上の活性金属が上記担体の表面近傍に担持されている層をいう。上記活性金属が担持されている層の厚さは元素マッピングによって求めることができ、担体の断面の活性金属の濃度分布をＥＰＭＡ（例えば、株式会社島津製作所製のＥＰＭＡ）で測定し測定結果より担体の表面からの距離に対する活性金属の含有量の分布を計算することによって活性金属が上記担体の表面近傍に担持されている層の厚さを求めることができる。 The present invention is a hydrogen peroxide decomposition catalyst for decomposing hydrogen peroxide in a liquid phase into water and oxygen, comprising a carrier made of an inorganic oxide material having pores, Pt, Pd, And an active metal containing at least one element selected from the group consisting of Ir, Ru, Rh and Os, and the thickness of the layer on which the active metal is supported in the vicinity of the surface of the carrier is 0.01 to 0.25 mm. A catalyst is provided. The “layer in which the active metal is supported in the vicinity of the surface of the carrier” as used herein refers to a region within 2.0 mm from the surface of the carrier (hereinafter, this region is referred to as “near the surface of the carrier”). This refers to a layer in which 9% or more of the active metal is supported in the vicinity of the surface of the carrier relative to the total content of the active metal supported. The thickness of the layer the active metals are supported can be determined by elemental mapping the concentration distribution of the active metal of the cross-section of the carrier EPMA (e.g., manufactured by Shimadzu Corporation EPMA) from the measured measurement results By calculating the distribution of the content of the active metal with respect to the distance from the surface of the support, the thickness of the layer in which the active metal is supported in the vicinity of the surface of the support can be obtained.
