Practical CO2 adsorption processes require adsorbents that can be easily and quickly synthesized at a reasonable cost, while maintaining a significant adsorption performance. In this research, a metal organic framework based on Cu and H3BTC was synthesized by the potentiodynamic method. Results showed that the nature of the solvent strongly affected the phase structure, morphology and specific surface area of the obtained material. In methanol, a mixture of 1D structure Cu-BTC (catena-triaqua μ-[1,3,5-benzenetricarboxylato]-copper (II) corresponding to the formula [Cu(BTC)(H2O)3)]n and micropillars structure Cu(BTC).3H2O was obtained. The 1D structure Cu-BTC had a plate shape and a small specific surface area of 21 m2/g. In ethanol, the 3D structure Cu-BTC (Cu3(BTC)2) was successfully synthesized. The obtained material has a cubic shape of size from 50 nm to 500 nm and a much better specific surface area of 620 m2/g. The 3D structure Cu-BTC offered a high CO2 adsorption capacity of 3.6 mmol/g at standard conditions, and 1.6 mmol/g at more realistic conditions.

动电位法合成基于 Cu 和苯-1,3,5-三羧酸 (H3BTC) 的金属有机骨架用于 CO2 吸附
实际的 CO 2吸附过程需要能够以合理的成本轻松快速地合成的吸附剂,同时保持显着的吸附性能。本研究采用动电位法合成了一种基于Cu和H 3 BTC的金属有机骨架。结果表明,溶剂的性质强烈影响所得材料的相结构、形貌和比表面积。在甲醇中,一维结构 Cu-BTC(catena-triaqua μ-[1,3,5-benzenetricarboxylato]-copper (II) 对应于式 [Cu(BTC)(H 2 O ) 3 ) ] n和微柱结构 Cu(BTC).3H 2获得了O。1D结构的Cu-BTC具有板状和21m 2 /g的小比表面积。在乙醇中,成功合成了三维结构的Cu-BTC (Cu 3 (BTC) 2 )。所得材料具有50nm至500nm尺寸的立方体形状和更好的620m 2 /g的比表面积。3D 结构 Cu-BTC在标准条件下提供 3.6 mmol/g 的高 CO 2吸附容量,在更实际的条件下为 1.6 mmol/g。
