Ordered mesoporous carbon as an efficient and reversible adsorbent for the adsorption of fullerenes.
An ordered mesoporous carbon, CMK-3, was synthesized using a mesoporous siliceous material, SBA-15, as the template. CMK-3 was characterized and used for the adsorption of fullerenes C60 and C70. It was found that the adsorption capacity of CMK-3 is 4 times higher than that of activated carbon. The adsorption equilibrium isotherms of C60 and C70 on CMK-3 were studied for both single and binary ...
pH-responsive megagates have been fabricated around mesoporous silica material SBA-15 in order to mechanize the mesopores. These megagates remain closed in neutral conditions, but open at pH 5. The capping components of the megagates were designed to be capable of controlling pores up to 6.5 nm in diameter. Selectivity of payloads with different sizes can be achieved through the use of differen...
Problem statement: Santa Barbara Amorphous (SBA-15) is significant mesoporous silica with exclusive and important properties of highly ordered mesopores, hydrothermally stable and thick wall, profusely large surface area and huge pore volume which render it as promising catalyst for wide applications. However, the purely siliceous SBA-15 which lacks of acidity characteristic hinders its ideal c...
آلودگی اکوسیستم های آبی به رنگ ها یکی از اصلی ترین معضلات زیست محیطی قرن حاضر است که نیازمند ارائه راه حل های فوری و موثر در جهت حذف این آلاینده ها می باشد. بسیاری از صنایع مانند رنگرزی، نساجی، کاغذ و پلاستیک از رنگ ها و حجم زیادی آب برای رنگ کردن محصولات خود استفاده می کنند. بدین ترتیب مقدار زیادی پساب حاوی رنگ تولید می شود. بسیاری از آنها سمی و سرطان زا هستند و وجود آنها برای ادامه حیات آبزیا...
برای بررسی توانایی tio2 در تخریب ساختار فنل از ماده فعال سطحی پلورونیک پی-123، پلورونیک اف-127 و سی تب استفاده شد. همچنین کاتالیست نوری m-tio2 ساخته و اثر آن بر تخریب ساختار فنل در آب بررسی شد. در قسمت دیگر از پایه sba-15 استفاده و کاتالیست ti-sba-15 ساخته و اثر آن بر تخریب فنل بررسی شد.
A novel SBA-15 supported catalyst PdL(n)@SBA-15 containing a 2-pyridyl-1,2,3-triazole ligand framework was prepared via a "click" route, in which the click-triazole acted as both a stable linker and a good chelator. The catalyst was characterized and applied for the aerobic oxidation of alcohols, and the product was obtained in up to 98% yield.
BACKGROUND Removal of mercury from aqueous environment has been highly regarded in recent years and different methods have been tested for this purpose. One of the most effective ways for mercury ions (Hg(+2)) removal is the use of modified nano porous compounds. Hence, in this work a new physical modification of mesoporous silica (SBA-15) with 1, 3, 5 (Trithiane) as modifier ligand and its app...
