There isn't any difference between the guano graphene and the non-guano graphene in terms of structure -- look at figures 1 and 2. Figure 2A is clearly 4 of the same spectra because thermal exfoliation in the presence of guano doesn't create a materially different graphene than not in the presence of guano.

The rest of the paper is poking fun at all of the referenced papers that just have inconsistent electrochemical experimental setups that produce apparently increased electrocatalytic effects.
