The invention belongs to a catalytic material, and particularly relates to a quinary high-entropy alloy catalytic material and application and an application method thereof. The quinary high-entropy alloy catalytic material comprises five metal elements, namely Fe, Co, Ni, Cr and Cu. The atomic ratio of the Fe to the Co to the Ni to the Cr to the Cu is 1: (0.95 to 1.05): (0.95 to 1.05): (0.95 to 1.05): (0.95 to 1.05). The quinary high-entropy alloy catalytic material can realize high-efficiency carbon monoxide catalytic oxidation, improves the upper limit of conversion rate and the lower limit of output carbon monoxide, has extremely long service life, is not easy to age or lose efficacy due to oxidation, has good heat resistance, and has extremely wide application prospects in heavy industry waste gas treatment. 本发明属于催化材料，尤其涉及一种五元高熵合金催化材料、其应用和应用方法。所述五元高熵合金催化材料包括Fe、Co、Ni、Cr和Cu五种金属元素；所述Fe、Co、Ni、Cr和Cu的原子比为1：(0.95～1.05)：(0.95～1.05)：(0.95～1.05)：(0.95～1.05)。本发明五元高熵合金催化材料能够实现高效率的一氧化碳催化氧化，提高了转化率上限以及输出一氧化碳下限，同时具有极长的使
