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.
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?
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
@@drarifsiddiquie5443 sir I'm using filter paper to filter the content it get stucked in the filter paper itself and I'm not able collect anything Remaining and all I get properly as mentioned in the video What i have to do for filtration and I used Dil HCl for washing Please clarify my queries Thankyou in advance
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
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
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?
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
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.
Ankita Singh you should try to make your reaction more environmentally friendly, therefore an alternatives for such dangerous(hazardous) reducing materials has to be employed!
Please, make an erection this video as it is not adequate to make a GO solution. I refer to use some bath sonication procress, ultra centrifugation ,filtration and washing, dialysis everything is important to produce a high purity, clean GO acquous solution
@ranikabir I try for making graphene oxide i go through so many literature also used sonicator, centrifugation and washing seven or eight times but XRD peaks are not matching with the literature i can't find what is the reason behind them kindly share yours experience Thank you.
