RE: EXTERNAL: Re: [Vo]:Toyota Group Claims Breakthrough In Artificial Photosynthesis

[Roarty, Francis X]

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 R&D 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. . . .

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 R&D 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.
