PROBLEM TO BE SOLVED: To provide an aldehydes remover using a ruthenium (Ru) carrier that can remove aldehydes efficiently at lower temperature than that of a ruthenium Ru particle carrier that forms hexagonal closest packed structure (hcp).SOLUTION: There is provided an aldehydes remover using a Ru (fcc) carrier comprising: Ru (fcc) particles that forms face-centered cubic structure and a carrier selected from among an activated carbon, an activated carbon fiber, alumina, silica, zeolite, a composite oxide or a porous metal complex.EFFECT: The Ru (fcc) carrier exhibits an excellent removing rate of aldehydes at lower temperature than that of a Ru (hcp) carrier, for example, even at 80°C.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】六方最密充填構造(hcp)を取るルテニウム(Ru)粒子担持体より低い温度で、アルデヒド類を効率よく除去できるRu担持体を用いたアルデヒド類除去材の提供。【解決手段】面心立方格子構造を取るRu(fcc)粒子と活性炭、活性炭素繊維、アルミナ、シリカ、ゼオライト、複合酸化物又は多孔性金属錯体より選択される担体と、から構成されるRu(fcc)担持体を用いるアルデヒド類除去剤。【効果】前記Ru(fcc)担持体はRu(hcp)担持体より低い温度、例えば80℃でも良好なアルデヒド除去率を示す。【選択図】図1
