Nanostellar, a Silicon Valley developer of advanced materials, has completed the commercialisation of a gold-based catalyst. NS Gold is now in production with one of the four largest European diesel car manufacturers, and the World Gold Council has provided an additional investment which will help the company to accelerate wider commercial adoption of NS Gold.
 The inclusion of gold in this technology provides significant benefits for diesel vehicle manufacturers, providing emission reductions of up to 30%, manufacturing cost reductions, or alternatively improved fuel economy.
Other catalytic converters use precious metals to reduce noxious emissions, and the potential to use gold in this type of application has long been considered by the industry. But until Nanostellar's breakthrough the technical challenges concerning catalyst durability prevented its use. Following rigorous performance and durability testing, the NS Gold catalyst has proven to be fully compliant with the current European vehicle emissions standards.
"This is one of the most advanced and exciting applications of gold in technology, with the potential to address stricter legislation on reductions in engine emissions cost-effectively, while broadening the technological uses for gold," comments Dr Richard Holliday, director, technology at the World Gold Council.
"We look forward to continuing our strategic partnership with this cutting-edge, innovative company and sharing our expertise to help spur further progress in other technologies," he continues.
Pankaj Dhingra, CEO of Nanostellar, adds: "We welcome the continued support of the World Gold Council. The performance benefits, durability and manufacturability of NS Gold-based diesel oxidation catalysts have now been proven. In addition, the application of Nanostellar's materials design process, rational design, has provided us with a pipeline of exciting new materials that are undergoing durability tests."
