Well, this is what the flask looks like when I reacted H2SO4 + Al2O3 + Fe2O3 Any idea of what that is?
Next I think I will try Titanium Oxide, Silicon oxide, Copper oxide,Zinc Oxide, Aluminium oxide, and Iron Oxide then permutate them to see all the different versions of this material. There will be more pictures coming up, I am seeking a materials like carbon nano-tubes or nano-particles. Let's see if we can't reach a hyper oxidation state. I want to see metallic oxygen bonds.
Note: It doesn't look like a sulfate.
I don't know how you can say it doesn't look like sulphates. You have a greenish/whiteish mixture there. My guess is you have a mixture of all three sulphates. If copper sulphate is not fully hydrated it will be white - should go blue when more water is added.
All three sulphates are water-soluble, so if you try to dissolve them up in distilled water, filter off any unreacted oxides that may be making it look dirty - or let it settle and decant the supernatant liquid, leaving the sludge behind - and then from the clear liquid you may be able to evaporate the water slowly and get some decent crystals, instead of this mixture. Why not try it and see?
But I must warn you that treating metal oxides with sulphuric acid is not likely to give you anything but boring old sulphates.
What do you mean by a "hyper" oxidation state? There are Fe +4 and Fe +6 oxidation states known, but these are rare and you won't get to them using sulphuric acid. Similarly you can get Cu +3 in rare cases, but not with sulphuric acid. (You have no chance at all of getting Al in any oxidation state >3 since that would involve breaking into the electron shell below the valence shell. The ionisation energy for that process is 120eV, way above what chemistry can do for you.)
As for "metallic oxygen bonds", I do not understand this. Metallic bonding involves delocalised valence electrons, for which you need an element in its reduced form that is willing to give up one or more electrons into the delocalised system - in other words a metal. How can oxygen play a role in this?
P.S. None of this appears to relate to carbon nano-tubes, which are formed of elemental carbon, i.e. in an oxidation state of zero.
