What's going on here? Graphene hoax?

This guy claims to make graphene, by pouring some clear liquid on a black powder. He appears to have several pseudoscinece claims but if it isn't graphene what is it? Ash?

He even gets them to eat the stuff! :o What do you think?

that little indian girl has a belly full of conductive material and can now be hooked up to a smart phone.why cant that guy just be an honest vodka salesman instead?vodka has been proven to get you dead drunk but i guess he doesnt want to be famed for exploiting indians.potion vendors will always be around but no one will ever top coca cola.porn,graphene and coke is the future.

Just another pseudo-scientific hoax, nothing important.

This pretty much sums it up: http://www.waterfreedomrevolution.com/the-technology/bluenes...

Prob the hydrogen peroxide on graphite oxide method.

there is a youtube video on making it, by some chap that has a half dozen other attempts there also.

edit: there it is from an older thread

I worked with a guy who must have been suckered in by Petrik several years ago.

He had a vial of this fluffy black powder he was calling "graphene" and said that he got from a guy in Russia, who produced with from some aqueous reaction, which generated piles of the stuff. He said he (the guy I knew) was working on commercializing it. Some months later he quit to pursue other business interests, and I heard no more about it.

I had never heard about this at the time, but told him I didn't think the stuff in the vial was really graphene.

And I hadn't heard anything about this again until now.

Why the fuss, make it in your blender with some soap...

morganism: I saw that video but it doesn't look like the same reaction, at least to me.

To me it looks like the liquid initiates a decomposition of the black substance but I have no idea what either might be. The reaction has a passing similarity to ammonium dichromate decomposion but the product is obviously different. Another fact which is interesting besides the huge volume produced is that the product seems moldable. In one of the clips it is molded into a ball shape which sticks together quite well, something impossible if the product was carbon, as might be produced by decomposing sugar with sulfuric acid.

The disproportionation of graphene oxide can be quite energetic. All it takes is a heat source to trigger it. Different metal ions added to it can affect the reaction.

Oh, but yes, the old guy is full of it.
