When graphene oxide is doped with Nitrogen, which atom will be replaced by Nitrogen: Carbon or Oxygen?

In N doped graphene Carbon is replaced by N in the graphitic structure. If it is same in case of N doped Graphene oxide then why oxygen containing functional groups are reduced as indicated by...

Do TMB and Graphene oxide give any colour together?

I added TMB to GO particles before adding hydrogen peroxide for testing peroxidase like activity, it gives colour even in the absence of hydrogen peroxide.Do TMB and GO have any kind of chemical...

I have preapared a solution of TMB Hydrogen peroxide and Graphene oxide it is not showing any colour.Why?

The literature reveals that this solution should have blue colour as H2O2 oxidizes TMB. I dont know what went wrong why there is no colour? what can be the possible reasons?

I prepared graphene oxide and dried it but later when I used it got moist immediately.i dried it again but later when used it was moist again. why ?

I have prepared GO before but it was dry each time I used it, but this time it is getting moist again and again. whats wrong?

If as prepared graphene oxide is excited at shorter wavelength in Raman spectroscopy, what can we infer about its energy states and hence its purity?

I prepared graphene oxide and it showed results at short wavelength of 457 nm but other students got results at 514 nm. so i want to know about the enrgy states and quality of my sample?

Why aren't most metal oxides insoluble in water?

Why BaO (s) + H2O(l) ---> Ba 2+(aq) + 2 OH - (aq) if Oxygen loves owning all the electrons, why would it bind to hydrogen which competes with Oxygen for electron ownership more so than...

Why chloride turns into chlorine gas in a Downs cell?

I imagine the battery drives the graphite into a carbocation, then chloride is oxidized to donate the electron to the carbocation, but what pushes the lost electrons of chloride to be shared...

Hussein Shanak

Please see the attached file

Thomas Walther

by definition, graphene is a 2D material so there can be no bulk (3D) values for any of its properties

Ayesha Saleem

Thank you for your reply Mr.Walther but how can I find the radius of graphene oxide without knowing its bulk band gap energy?

Mr. Hussein Shanak kindly resend the file again it has not been attached.
