[@alphajohnas374]

Thank you very much. Very clear and easy to understand. I was able to synhtétiser GO, thanks for the video

hi, i'm about to do research using GO, is this method is quick and simple based on your experience?

thanks alot for uploading sir. may i know that whether we can use ice bath while adding water or not ?

Some articles make graphite oxide via the modified hummer's method, how might the procedure in synthesizing graphite oxide be different from making this graphene oxide?

[@techtimes1985]

Great, I have subscribed

[@HojjatNadimi]

Hello friends, I hope you are all well. I needed graphene oxide for my thesis, so I followed the steps mentioned in the video and obtained a solution. I intend to use it to spread zinc oxide on a substrate. Is the obtained solution suitable for this purpose? Also, how can I determine the concentration of the synthesized graphene oxide solution? Please advise.

[@victornguyen167]

I think that the result is Graphite Oxide?

[@niteshdogra8306]

I'm working on graphene can you tell me about the colour of final product?? And also about the filtration process

[@drarifsiddiquie5443]

It’s may turn deep yellow ..but you will get it in black color when dried…follow decantation till it is neutral then can oven dry to get the final product

sir, please share the journal reference. because I need a journal reference for the process of making this graphene 🙏

Thanks a lot

[@alexeyeliseykin9754]

Excus me, what is the concentration of these reagents?

[@iqraurooj6516]

25ml sulphuric acid 1g graphite powder 3g of potassium permanganate 50ml water (dropwise) 100 ml of water after dark brown color appears 5ml of Hydrogen peroxide to stop the reaction

[@alexeyeliseykin9754]

@@iqraurooj6516 amm hydrogen peroxide to stop the reaction? But is hydrogen peroxide needed not for the oxidation of graphite !?

[@iqraurooj6516]

Alexey Eliseykin tbh i am not sure, because i haven't performed this in lab but learnt it on Google classroom lol. i think potassium permanganate will oxidise graphite and hydrogen peroxide is added at end to stop the reaction

[@omsingharjit]

What would be the concentration of h2so4 ?

[@Kavster92]

This is a rough outline of the method not a guide on how to create it. I advise you simply google Graphene Oxide by Hummers Method for the absolute formulas/concentrations.

Then use ultra sonicator…all we need Is centrifugation ..magnetic beads are the cheapest options ..

[@syafiqasyraf830]

What if when i add water, the color of the solution does not change to brown? The color stay black even after i put the hydrogen peroxide. Do that mean the graphite does not oxidize?

[@aminumagaji7050]

Syafiq Asyraf yeah you may try to change your graphite! Alternatively, you can check at the purity of your reagents

[@muhammadnisarqasim636]

why add 25 ml sulphuric acid . can we increase or decrease amount . Please guide me sir about .

definitely we can....but this is not the original hummers method..see original paper

Why we are placing ice, what is it's role....?

[@DurgaramProfDhawan]

It is an Exothermic reaction. So temperature rise happens. Hence Ice bath needed

[@rahulsharma-sx2jv]

My go turns green color after adding di what is the reason

[@CannonballCircuit]

why is the water step very dangerous?

[@zenmanproject]

Because adding water to acid produces an exothermic reaction (heat). It can cause the water to boil and erupt splashing acid on you. To be safe you want to use AAA or "always add acid" that way the heat is transferred into the water and gives it a chance to cool down before vaporizing into steam. Since the order of this is to add the acid at the end, they suggest adding it slowly so it doesn't boil and hurt you. If I was wrong about any of this, hopefully someone smarter than me will correct me

[@bartoszbarejko1585]

And what next with graphite oxide. Still long way to make Pure elastic powder like graphene.

[@zenmanproject]

You can make ink out of graphite oxide, you can add GO to concrete and plastics to make them stronger.

[@omsingharjit]

You can print super capacitor

There is no use of sodium nitrate. Please explain.

Why we use ice bath in hummer method?

[@Sivakumar_Murugesan]

Exothermic reaction, control heat

What is need of ice bath?

[@drarifsiddiquie5443]

Just to cool down..the reaction is highly exothermic
