This article elaborates on three deoxidation mechanisms, including combustion deoxidation, catalytic oxidation, and chemical absorption. It mainly summarizes the preparation processes, deoxidation principles, and research status of deoxidants for precious metals, copper based, iron based, manganese based, molybdenum based, and porous ceramic materials. By comparing the preparation costs, deoxidation effects, and post-treatment procedures of different deoxidizers, the advantages and disadvantages of each deoxidizer are pointed out. Among them, noble metal deoxidizers have the best deoxidation effect, but they consume reducing gases such as methane and hydrogen, and produce impurities such as CO2/H2O; Non precious metal deoxidizers are inexpensive, but their deoxidation effect is slightly poor and their usage temperature is relatively high; Non metallic deoxidizers have advantages and disadvantages such as being less prone to sulfur poisoning. Finally, based on the characteristics of the aforementioned deoxidizers, two development directions for deoxidizers are proposed, namely non-metallic deoxidizers and composite deoxidizers with strong adsorption and catalytic properties.
