چکیده

One approach to mitigating global warming is the capture and storage of CO۲ as the majorgreenhouse gas [۱]. Materials that are commonly used for CO۲ adsorption include activated carbon,zeolites [۲], and metal-organic frameworks (MOFs) [۳]. HKUST-۱ (also known as MOF-۱۹۹) is awell-known metal-organic framework that has been extensively studied for its potentialapplications in gas storage and separation. In this work, HKUST-۱ was investigated as anadsorbent for CO۲. HKUST-۱was synthesized using the hydrothermal method and its chemicalproperties were investigated using various characterization techniques including XRD, FTIR,FESEM, BET, and TGA. It was shown that HKUST-۱ has a crystalline structure with a surfacearea of over ۱۷۰۴ m۲/g, and a petal-shaped molecular structure. It also showed thermal stability upto a temperature of ۳۶۶°C. The results of CO۲ adsorption showed that the amount of carbon dioxideadsorption by HKUST-۱ at ۲۰°C, ۳۰°C and ۴۰°C and ۱bar was ۳.۷۸۸, ۳.۴۱۷, and ۳.۰۸۸mmol/g,respectively. However, in ۱۰ bar and the same temperatures, its adsorbtion improved to ۹.۰۹۰,۸.۷۸۲, and ۷.۷۲۴ mmol/g, respectively. Therefore, it can be concluded that the amount of carbondioxide adsorption enhanced with increasing CO۲ pressure and decreases when temperatureincreases. Therefore, HKUST-۱ could be suggested as a promissing CO۲ adsorbent at moderatetemperatures.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
