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?

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?

Thank you for your reply Sir.

Ahmed khalaf Reyad Raslan

Graphene oxide is surface active material has many fuctional group , in case that the sorption process was chemosorption in this case the sp2 electron can convert to sp3 so you may get color

Yes may be thats the reason Thank you.
