[ 1 ] - Chitosan supported bimetallic Pd/Co nanoparticles as a heterogeneous catalyst for the reduction of nitroaromatics to amines
A new bimetallic nanocomposite of chitosan was prepared. Pd and Co nanoparticles were deposited on chitosan to produce a new heterogeneous recyclable catalyst for use in the bimetallic catalytic reduction reaction. The catalyst was characterized with common analysis methods for nanocomposites including Energy Dispersive X-Ray Spectroscopy, X-Ray Diffraction pattern, Thermal Gravimetric Analysis...
[ 2 ] - Pd and Fe3O4 Nanoparticles Supported on N-(2-Aminoethyl)Acetamide Functionalized Cellulose as an Efficient Catalyst for Epoxidation of Styrene
A new efficient heterogeneous catalyst was introduced for the epoxidation of styrene. The catalyst was obtained from functionalization of cellulose with N-(2-aminoethyl)acetamide, and then deposition of nanoparticles and Pd(0) nanoparticles on the modified cellulose. The Fe3O4 nanoparticles were deposited via chemical oxidation in basic media and Pd(0) nanoparticles we...
[ 3 ] - کیتوسان اصلاح شده با کبالت(II) بعنوان کاتالیزوری سبز برای واکنش اکسایش استایرن به استایرن اکساید
کیتوسان بعنوان یک بستر سبز برای کبالت(II) مورد استفاده قرار گرفت. کیتوسان-کبالت(II) بعد از شناسایی با استفاده از روش های مرسوم شامل طیف سنجی مادون قرمز تبدیل فوریه، طیف سنجی جذب اتمی شعله، طیف بینی توزیع انرژی الکترون، پراش پرتو ایکس و وزن سنجی حرارتی بعنوان یک کاتالیزور ناهمگن زیست سازگار در واکنش اکسایش استایرن مورد استفاده قرار گرفت. واکنش در حضورکاتالیزور تهیه شده و سه برابر مولی اکسنده سبز...
[ 4 ] - Reduction of Nitroaromatics to Amines with Cellulose Supported Bimetallic Pd/Co Nanoparticles
Pd and Co nanoparticles were deposited on cellulose for use as a heterogeneous catalyst in the bimetallic catalytic reduction reaction. The catalyst was characterized with Energy Dispersive X-Ray Spectroscopy, X-Ray Diffraction pattern, Thermal Gravimetric Analysis, Flame Atomic Absorption Spectroscopy, and Transmission Electron Microscopy, and applied in the reduction reaction of nitroarom...
[ 5 ] - Synthesis of some Polyol Esters and Diesters Catalyzed with SnO2 and Nano-SnO2
Esterification reactions of some polyols and diols were investigated in the presence of SnO2 and nano-SnO2 and the results were compared with the catalyst-free conditions. High conversions were obtained for most of the reactions in the presence of SnO2 and nano-SnO2 which shows the high catalytic activity of SnO2 and nano-SnO2</sub...
