در قسمت اول این تحقیق، کمپلکس [fe-schiff base] با روش اشباع سازی در نانوراکتورsba-15 تثبیت شده است. این نانو کاتالیزور به وسیله تکنیک هایxrd ،tem ، bet (جذب – واجذب نیتروژن(، ir، uv و tga شناسایی شده اند. الگوی xrd و تصویر tem مربوط به [fe-schiff base/sba-15] ساختار هگزاگونال منظم را در مزوحفره های سیلیکا نشان دادند. ایزوترم جذب – واجذب نیتروژن [fe-schiff base/sba-15] بر طبق دسته بندی آیوپاک بر...
The electrochemical generation of N-heterocyclic carbenes (NHCs) offers a mild and selective alternative to traditional synthetic methods that usually rely on strong bases air-sensitive materials. use electrons as reagents results in an efficient clean synthesis enables the direct NHCs various applications. Herein, electrogenerated organocatalysis, organometallic chemistry is explored.
Anodic electrogenerated chemiluminescence (ECL) of the self-assembled peptide nanotube (PNT) modified electrode in an aqueous system was observed for the first time using tri-n-propylamine (TPrA) as the coreactant. The potential application of ECL PNTs in analytical chemistry was also demonstrated using Cu(2+) as an example.
In this work, the possibility of using reactions electrogenerated titrants with phenolic compounds was studied and a method for their coulometric determination in medicaments by galvanostatic coulometry developed. The research objects were: rutin, salicylic acid drugs containing such as «Ascorutin», «Salicylic Paste» Ointment» Russian manufacture. Electrogenerated halogens (Cl2, Br2 I2) hexacya...
