as far as I'm concerned, graphene oxide(GO) is usually utilized for metal coating.
if we suppose that iron precursor such as iron chloride is coated on reduced graphene oxide during which GO is reduced with a reducing agent like hydrazine and metal precursor is oxidaized, what mechanism can explain that?
I'm very confused which one of both chemical and physical adsorptions induce that reaction
please, I need your help to understand the mechanism.
I'd very appreciate it if you'd give me comments
Dear Jason:
If you reduсing the surface of graphene oxide and iron ions with hydrazine, then the two substances redusing. Reducing properties of hydrazine more than graphene. I guess you can write the chemical reaction. Simplistically.
2CO(grafene oxide) +H2N-NH2 = 2C (grafene)+ 2H2O + N2
2Fe(OH)2+ + H2N-NH2 = Fe +2H2O +N2+H2
We reduced hydrazine complex of copper ion to cellulose.
Regards.
I m not sure if I get you.
Let me request other answers to mg question.
I should ve clarified what a metal oxide is.
I usually synthesize iron oxide, epscially Fe3O4(magnetite) from various iron precursors under nitrogen atmosphere.
One of my works is to coat megnetite on graphene nanosheets by, I guess, oxidation-reduction reaction.
I assume that oxygens of graphene oxide, which is fabricated from graphite to hold oxygen-functional groups on the surface of graphite, transfered to iron, making Fe3O4. It can be expressed that iron precursor undergoes oxidation and graphene oxide is affected by reduction. Am I right? I wonder if the mechanism for coating metal oxide on graphene nanosheets is my assumption. Please answer me^^;;;
Dear Jason:
You turn to someone? You are within 2 months is not grateful for the answer to your first question. Now you ask a new question. Do you think that the professor a lot of free time?
Regards.
