چکیده
A facile two-step strategy was used to preparation Nano composite of reduced graphene oxide doped conducting polymer poly (3,4-ethylenedioxythiophene) decorated with nickelnanoparticles (NiNPs) onto a glassy carbon electrode (GCE). Composites of poly (3,4- ethylenedioxythiophene):poly (styrene sulfonate) (PEDOT:PSS) and reduced graphene oxide (RGO) have been prepared by solution mixing and have been fabricated as an beneficial supportfor Ni nanoparticles on a GCE. NiNPs were electrodeposited on PEDOT+RGO support by applying constant potential to nickel ions solutions. Then, NiNPs/PEDOT+RGO/GCE applied as efficient electro catalyst for electro oxidation of urea.The electro catalytic properties of NiNPs/PEDOT+RGO modified glassy carbon electrode toward the oxidation of urea were analyzed by cyclic voltammetry (CV) andchronoamperometry (CA). Cyclic voltammograms indicated the high electro catalytic activity of NiNPs/PEDOT+RGO is mainly described to the good electrochemical activity of PEDOT+RGO composites and the well-dispersed Ni nanoparticles on the surface of PEDOT+RGO composite.Images of scanning electron microscope also was used to checking the changes on the surface of the electrode after modification. The composite exhibits a good stability after 1000 s and causes a noticeable intensification electrochemical effective surface area of modified electrode. Theelectrochemical effective surface area of four modes of electrode including the bare GCE, NiNPs/PEDOT/GCE, PEDOT+RGO/GCE and NiNPs/PEDOT+RGO/GCE were calculated 0.28, 0.71, 0.81, 0.98 Cm2 respectively.کلیدواژه ها

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.
