TOKYO Oct 1 Japan's Mazda Motor Corp (7261.T)
said on Monday it has developed the world's first catalyst for
cars that employs single-nanotechnology to create a material
structure that slashes platinum and palladium use by 70 to 90
The reduction results in no change in the performance of the
automotive catalyst, which uses platinum, rhodium and palladium
to trigger a chemical reaction with polluting nitrogen oxide,
carbon monoxide and hydrocarbons to clean tailpipe emissions.
Domestic rival Nissan Motor Co (7201.T) in July also said it
had developed a catalyst for gasoline cars that uses
nanotechnology to prevent clustering of the catalyst's fine metal
particles under high temperature conditions. That would halve the
use of precious metal components, it had said.
Single-nanotechnology can control smaller particles than
Automakers have been burdened with higher-than-expected
commodity prices, and are looking for ways to reduce material use
to save costs.
A Mazda spokesman said the company had not decided yet when
it would first employ the technology on a production model. It
also has no plan for now to share the technology with controlling
shareholder Ford Motor Co (F.N).
