Green Car Congress: Rutgers chemists develop new high-performance, platinum-free electrocatalyst for electrolysis; licensing available noting Rutgers Chemists Develop Technology to Produce Clean-Burning Hydrogen Fuel | Media Relations
From the first one:
Liberation from platinum. A sight for sore eyes. Liberation from fossil fuels is now more in sight. Most alternative energy sources are best suited for delivering electricity, so with electrolysis, one can get a feedstock for synfuels: hydrogen. One can use it directly, but it is a gas with a *very* low boiling point. But one can combine it with CO2 to make hydrocarbons in the Fischer-Tropsch processWP . Even short of that, one can store the hydrogen and then recombine it with fuel cells.
One of this material's inventors some years back: Dr. Tewodros Asefa - Multifunctional Nanomaterials - YouTube: "Multifunctional Nanomaterials: Form Synthesis to their Applications for Efficient Catalytic Conversion of Fine Chemicals"
So it looks like it's for real. It isn't the final word in platinum-free electrode materials, I'm sure, but it's a valuable proof of concept.
Room-temperature fuel cells can already have platinum-free electrodes, like what this company advertises: CellEra | Platinum Free Membrane Fuel Cell Technology
Platinum is a rare and expensive metal, comparable to gold. Avoiding platinum in electrodes will thus enable widespread use of electrolytic and fuel cells without straining platinum supplies. It has been used because it is a noble metal, one that is almost corrosion-proof. But organisms' energy metabolism contains approximate analogues of both electrolytic and fuel cells, and also photovoltaic cells, and it does so without a platinum atom in sight.

Quote:
Rutgers researchers have synthesized cobalt-embedded nitrogen-rich carbon nanotubes (NRCNTs) that 1) can efficiently electrocatalyze the hydrogen evolution reaction (HER) with activities close to that of costly platinum and 2) function well under acidic, neutral or basic media alike, allowing them to be coupled with the best available oxygen-evolving catalysts—which also play crucial roles in the overall water-splitting reaction. ... The materials are synthesized by a simple, easily scalable synthetic route involving thermal treatment of Co2+-embedded graphitic carbon nitride derived from inexpensive starting materials (dicyandiamide and CoCl2). |
