摘　　要：碳捕集、利用与封存技术已成为我国实现碳达峰、碳中和目标的重要技术支撑。基于此,本文以亚铁氰化钾(K_(4)Fe(CN)_(6)·3H_(2)O)和氯氧化锆[ZrOCl_(2)·8H_(2)O]为原料合成了双金属材料(Fe-Zr),并借助三乙烯四胺(TETA)对其进行改性;利用氧化石墨(GO)与改性后材料进行复合,制备了新的CO_(2)吸附剂Fe-Zr(TETA)/GO(n);通过实验研究了CO_(2)吸附性能受气体流速、吸附时间、吸附温度、氧化石墨含量等的影响情况。实验结果表明:当吸附温度为30℃,气体流速为20 cm3·min^(-1),氧化石墨含量为9%时,Fe-Zr(TETA)/GO(n)的CO_(2)吸附量最大,为211mg·g^(-1);吸附剂的质量和CO_(2)吸附量在循环10次后仍能维持稳定。The technology of carbon capture,utilization and storage has become an important technical support for our country to achieve the goal of carbon peak and carbon neutralization.Based on this,the bimetallic material of Fe-Zr was synthesized from K_(4)Fe(CN)_(6)·3H_(2)O and ZrOClH_(2)·8H_(2)O and modified by triethylenetetramine(TETA).A new CO_(2) adsorbent,Fe-Zr(TETA)/GO(n),was obtained by compounding graphite oxide(TETA)with the modified material.The effects of gas flow rate,adsorption time,adsorption temperature and graphite oxide content on the adsorption performance of CO_(2) were studied by experiments.The results indicate that the maximum adsorption capacity of Fe-Zr(TETA)/GO(n)is 211 mg·g^(-1)when the adsorption temperature is 30℃,the gas flow rate is 20 cm^(3)·min^(-1),and the graphite oxide content is 9%.The mass of the adsorbent and the adsorption capacity of CO_(2) can remain stable after 10 cycles.
