PROBLEM TO BE SOLVED: To provide a low temperature removal catalyst and a removal method for aldehyde gas, which have high performance of aldehyde gas removal in a low temperature region without using a noble metal and have little effect on environmental pollution and human body.SOLUTION: The problem can be solved by: using a composite metal catalyst containing cerium and copper making the catalyst come in contact with aldehyde gas which is oxidatively decomposed and having decomposition products of the aldehyde gas adsorbed and removed by the catalyst.SELECTED DRAWING: NoneCOPYRIGHT: (C)2017,JPO&INPIT【課題】貴金属を用いずに、低温領域において、アルデヒド類ガスの除去性能が高く、かつ、環境汚染や人体への影響が低いアルデヒド類ガスの低温除去触媒と除去方法を提供すること。【解決手段】セリウムと銅を含有する複合金属触媒を用い、アルデヒド類ガスに接触させて酸化分解させ、かつアルデヒド類ガスの分解生成物を触媒に吸着除去させることで上記課題を解決する。【選択図】なし
