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]

NAGOYA (Nikkei)--A Toyota Motor Corp. (7203) group research firm said Tuesday
that it has
developed technology that duplicates how plants make energy, using only
sunlight, water and
carbon dioxide.
Artificial photosynthesis is not new, but Toyota Central RD Laboratories
Inc. says it has found
the world's first method that does not require special additives.
The reaction uses a metal-coated semiconductor as a photocatalyst and gives
off oxygen and formic
acid as byproducts.
Developing practical uses will likely take some time. The process converts
sunlight into energy
at an efficiency of 0.04%, making it only about a fifth as good as plants in
general, according
to senior researcher Tsutomu Kajino. . . .
