PROBLEM TO BE SOLVED: To provide a catalyst that can, when carrying out the processing of gaseous compounds such as VOC, ammonia, hydrogen sulfide and carbon monoxide by catalytic combustion system, process even when the gaseous compounds enter the catalytic bed before the temperature of the catalyst reaches a temperature for exhibiting an activity as a thermal catalyst.SOLUTION: Provided is a catalyst having a matrix comprising pores having an average pore size of 0.7 to 3 nm, and a chromium oxide quantum dot, and in which the chromium oxide quantum dot is retained within the pore of the matrix.SELECTED DRAWING: Figure 1 【課題】触媒燃焼式でＶＯＣ、アンモニア、硫化水素、一酸化炭素等のガス状化合物の処理を行う際、触媒が熱触媒として活性を発揮する温度に達する前に触媒槽にガス状化合物が入って来ても処理することができる触媒を提供する。【解決手段】平均細孔径が０．７〜３ｎｍである細孔を有するマトリックスと、クロム酸化物量子ドットとを有し、前記クロム酸化物量子ドットが前記マトリックスの細孔内に保持されている触媒。【選択図】図１
