Will any crap we put into graphene increase its electrocatalytic effect? (2020)

The paper did not answer the question in the title, since it used only one kind of crap. A broader study is called for.

I guess they were trying for an IgNobel Prize? However, they don&#x27;t report anything on the stability of the catalyst under reaction conditions, that is how many reaction cycles it goes through before losing catalytic effect.<p>If they don&#x27;t report the lifetime, it&#x27;s usually because the lifetime is crap, and all they have is a laboratory curiousity - which might, with futher diligent effort (and please, another research grant!), become industrially useful... maybe.

&gt; We demonstrate in the following text the meaninglessness of the never-ending co-doping of graphene. We decided to follow the hyperbole of ever multiplying dopants; however, instead of using expensive and toxic chemicals such as ammonia, fluorine, chlorine, 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.<p>What a wonderfully bat-shit paper.<p>&gt; In summary, we demonstrated that bird dropping-treated graphenes indeed make graphene more electrocatalytic than nondoped graphene.<p>Oh, never mind, just bird-shit, dang.

- <i>&quot;...societal impact not only in clean energy production and a cleaner environment but also on rural economies as guano once again becomes a valuable and highly sought-after product.&quot;</i><p>Apropos of nothing, the Guano Islands Act of 1856 is still, apparently, standing US law [0]. This research is an <i>exciting</i> opportunity for any who&#x27;d like to serve as mercenary privateers under the flag of the United States, while advancing science.<p>[0] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Guano_Islands_Act" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Guano_Islands_Act</a>

Not wanting to ruin a good joke, is this because imperfections in the alignment of otherwise pure substances provide opportunistic &quot;holes&quot; in structure for things like van der waals forces to work their magic?<p>I am reminded of the &quot;you can develop photos with a banana and a spoon&quot; (not really) stories, which underline the fundamentals of what photographic development is: a chemistry story which is not about the substances as much as about how base and acids combine. The photoreactive chemicals are highly specific, but the process of fixing them, and binding visible molecules to them or not, is more general.<p>Maybe the role of &quot;contaminants&quot; in graphine is similar? Not what it is, but what it DOES.

I adore that I live in a time where scientific articles have headlines with the word &quot;crap&quot;.
