| 中文摘要: |
| 为降低市场上铜基MOF（如HKUST-1）的制备成本，采用水热合成法，使用价格低廉的苯甲酸（BA）部分代替均苯三甲酸（H3BTC）制备HKUST-1，利用XRD、SEM和N2吸附脱附测试等对产物的结构和形貌进行了表征，同时考察了产物对亚甲基蓝的吸附性能。结果表明，在H3BTC与BA的摩尔比为3:1时，样品HKUST-1的性价比最高，其BET比表面积为1129.311 m2/g，对亚甲基蓝的最大吸附量可达402.501 mg/g。通过调整H3BTC与BA的摩尔比，可以成功制备高性能低成本的HKUST-1。 |
| 英文摘要: |
| In order to reduce the cost of copper-based MOF (i.e. HKUST-1), HKUST-1 was prepared by hydrothermal synthesis using inexpensive benzoic acid (BA), which partially replaced homophthalic acid (H3BTC). The structure and morphology of the product were characterized using XRD, SEM and N2 adsorption and desorption tests, while the adsorption performance of the product on methylene blue was also investigated. The experimental results showed that the sample HKUST-1 was the most cost-effective at the molar ratio of H3BTC to BA of 3:1, when its BET specific surface area was 1129.311 m2/g , and the maximum adsorption amount of methylene blue could reach 402.501 mg/g. By adjusting the molar ratio of H3BTC to BA, HKUST-1 with high-performance and low-cost could be successfully prepared. |
