I am working at TiO2/ graphene oxide nanocomposites for photovoltaic application. The samples are prepared hydrothermally which are in powdered form. Now I want to analyze the samples electrochemically through CV. How to prepare samples for CV analyses? Please suggest a brief details to prepare samples.
Уважаемый Ajaz Ul Haq ! Этот вопрос могут решить поставщики аппаратуры для полярографии. Но это очень сложно и долго.
Try the carbon paste electrode. The carbon paste is prepared by mixing your material with graphite powder and paraffin oil in a mortar with pestle. Put the paste into the hole of the electrode body and smooth the paste surface on a clean paper.
You can take your synthesized powder (~4 mg) and acetylene black (~1 mg) in 1 mL of IPA:H2O (3:2) mixture. Add 10 microL of 5% nafion to it and put it in ultrasonication to obtain a homogeneous ink.
Drop-cast 10-20 microL of this ink onto 3 or 5 mm Glassy carbon electrode and proceed with CV analysis.
