Strem Chemicals Expands Line of Gold Catalysts
(Nanowerk News) “Gold catalysis has had a recent resurgence” said Dr. Ephraim S. Honig, COO at Strem Chemicals “so we are pleased to be extending our line of gold homogeneous catalysts with the Project AuTEK’s heterogeneous line”.
Project AuTEK AUROlite™ gold catalysts perform in a variety of applications, such as gas phase CO oxidation, and may be used in respiratory protection devices. “In terms of low temperature CO oxidation our catalysts outperform the current employed Hopcalite and PGM catalyst technologies, furthermore we see a bright future for their use in liquid phase oxidations and other industrial relevant reactions”, said Jason McPherson, Engineer at Project AuTEK. Other applications that have been demonstrated include the low temperature oxidation of methane, the selective oxidation of D-lactose to D-lactobionic acid and the aerobic oxidation of aldehydes to esters among others.
Strem will be offering 3 varieties of the AUROlite™ line of gold catalysts, with a 1% loading of gold on aluminum oxide, titanium dioxide and zinc oxide supports. Each catalyst offered will be “commercial grade” as AuTEK has already scaled up its production capacity. The gold itself is deposited on the support via a proprietary process that yields gold nano crystallites of about 2-3nm.

Mintek, South Africa’s national mineral research organization, is one of the world’s leading technology organizations specializing in mineral processing, extractive metallurgy and related areas. Working closely with industry and other R&D institutions, Mintek provides service testwork, process development and optimization, consulting and innovative products to clients world-wide.
Mintek is a State Owned Enterprise (SOE), which reports to the Minister of Mining. About 35 per cent of the annual budget of R393 million is funded by the State Science Vote, with the balance provided by contract R&D, sales of products and services, technology licensing agreements, and joint-venture private sector companies. Mintek has about 750 permanent staff members, over half of whom are scientists, engineers and other technical R&D specialists.
About Project AuTEK
AuTEK is a joint venture between Mintek, and three major South African gold mining houses - Anglogold Ashanti, GoldFields and Harmony Gold. The main focus is to research and develop novel industrial applications for gold. AuTEK, housed at Mintek, involves research in the fields of catalysis, biomedical and nanotechnology.
The project AuTEK catalysis research and development unit was created in 2000. Since AuTEK is trying to bridge the gap between research and commercialization a scale-up and commercialization unit specifically focusing on the research outcomes of project AuTEK catalysis was formed in 2004.
