I wonder if Ni foam or nano powder coating could substitute for Pt? [snip]The bad news is that this highly efficient system requires an expensive, platinum-based cathode. The authors showed that it’s possible to use a cheaper, Molybdenum-based cathode, but efficiencies dropped. The authors suggest that it might be possible to find a cheap material that works well with this system but, as of their publication, they’ve not identified one.[/snip] Fran
