Simply print iron nitride, and bake.

they also use leaf carbon to make iron electrodes.

another good read 
that sounds like it could be fun. also nature could be
providing a nice electrode for things like fuel cells and coronal O3. we grow "ground cherry's" and they have a cool lantern like skeleton late in
the fall (after the fruit and leaf rot off).
that structure electroplate coated with copper could make an interesting catalytic copper acetone set-up.

or a nice coronal ozone electrode. say a larger maple or other leaf skeleton,
trimmed and plaster set to a tile or ceramic object. leading to a very nice and even distribution of charge at home relatively easily. I'm sure for
some applications the iron carbide skeleton would have to be prepared separately and applied later, and in some it could be done in place. I bet it
sure it would be a lot better than..
there could be some fun geometry and even reaction boundaries obtained with little effort. I'm still waiting for the fuzed quartz cylinder to my
furnace build project, and I have to fill my nitrogen cylinder but this could be a possible for me in the near future. thanks
