The invention provides a catalyst for eliminating dissolved oxygen in liquid. The catalyst includes a carrier and an active component, wherein the carrier is anion exchange resin with the uniformity coefficient larger than or equal to 1.1, and the active component is noble metal palladium, which is distributed in the carrier in an elementary substance form. According to the catalyst for eliminating the dissolved oxygen in the liquid, which is provided by the invention, the using environment temperature is increased to 60 DEG C from 40 DEG C in the prior art, so that the thermal stability is improved, the total organic carbon release amount is low, the application range is broadened, and the operation performance does not change. 本发明提供种用于消除液体中溶解氧的催化剂，其包括：载体，所述载体为阴离子交换树脂，所述阴离子交换树脂的均系数≤1.1；活性组分，所述活性组分为贵金属钯，所述贵金属钯以单质形态分布于所述载体内。本发明提供的用于消除液体中溶解氧的催化剂，将现有技术中使用环境温度由40℃提高到60℃，热稳定性提高，总有机碳释放低，拓宽了应用范围，运行性能不会发生改变。
