در این پروژه نانو کامپوزیت های na y/ hpw ، hpw / nay / aam ، hpw /nay/mcm -41 و hpw /nay/mcm -41 aam تهیه شدند و توسط روش های xrd, ft-ir و tga, sem مورد بررسی قرار گرفتند. نتایج بدست آمده نشان داد مقادیر قابل توجهی از hpw درون کامپوزیت ها ، حتی پس از شستشو باقی مانده است و این نشان دهنده آن است که هتروپلی اسید hpwبشدت به درون منافذ و سطوح کامپوزیت ها متصل شده است. برای تعیین فعالیت کاتالیست ها...
Abstract Microcystin-leucine arginine (MC-LR) is a carcinogenic toxin, produced by cyanobacteria. The release of this toxin into drinking water sources can threaten public health and environmental safety. Therefore, effective MC-LR removal from resources necessary. In the present study, hydrothermal method was used to synthesize novel ternary BiVO4/TiO2/NaY-Zeolite (B/T/N-Z) nanocomposite for d...
Single-crystal NaY(MoO(4))(2) thin plates dominated by high-energy {001} facets were hydrothermally synthesized under relatively mild conditions, free of organic additives, seeds and templates. The as-obtained NaY(MoO(4))(2) thin plates showed an excellent visible-light-responding photocatalytic activity for degradation of dyes in water.
BACKGROUND We report our recent study on the use of a zinc-modified NaY zeolite to decompose CO2 at temperature range between 300 and 550 °C. RESULTS At reaction 450 °C, we observed that 70% was converted with an insignificant quantity CO produced. Scanning electron microscopy Fourier transform infrared spectroscopic analysis neat spent catalysts confirmed presence carbon nanostructures after r...
One way to take advantage from out-of-specification biodiesel and waste tank bottom drainage is co-process them in a fluidized catalytic cracking (FCC) unit. The present work deals with the of oleic acid methyl ester (OAME) as model, under conditions close that FCC process over ZSM-5 Y zeolites, either protonated or sodium forms, towards deoxygenated compounds. Catalytic fast OAME pre-adsorbed ...
