We demonstrate in the following text the meaninglessness of the never-ending co-doping of graphine. We decided to follow the hyperbole of ever multiplying dopants; however, instead of using expensive and toxic chemicals like ammonia, flourine, chorine, boranes, etc, we took a page from the pre-Haber-Bosch era and sought natural materials for the fertilization of graphene and used guano as a dopant.

We show that we can create high-entropy, multiple-element-doped graphene with outstanding electrocatalytic properties for two industrially important reactions: oxygen reduction used in fuel cells and hydron evolution used in eletrolyzers.
