Precious-metal usage cut with Mazda nanocatalyst

Mazda Motor Corp. claims a world first with the application of its single-nanocatalyst technology, which is said to control material structures on an even smaller scale than nanotechnology, in the underfloor catalytic converter in the new Mazda3 (known as the Mazda Axela in Japan) when it goes on sale this year. The catalytic converter requires 0.15 g/L of precious metals, about 70% less than the 0.55 g/L required in the previous model. The single nanocatalyst increases the effective surface area of the precious metals used. By developing a method of controlling precious metal particles that are less than 5 nm (0.2 µin) in diameter as well as a proprietary catalyst material structure, Mazda created a catalyst that features single-nanosized precious metal particles embedded in fixed positions; there is no agglomeration of the particles, it claims.

Thermal imaging data obtained from a FLIR high-performance camera shows that the expected turbine output temperature is approximately 285°C when the helicopter is in forward flight. However, during hover operations a steady state temperature of about 343°C will be reached.
