Will Gold Replace Platinum in Catalytic Converters?

Gold shares some, but not all, of the pollution cleansing benefits of platinum. And with gold prices substantially lower than platinum, more and more people have been looking for ways to swap out platinum for gold.

As of December 9, 2007, platinum, palladium and rhodium were the best metals available for purifying the air through the use of catalytic converters… a fact that plays a huge role in the pricing of those metals. While we often associate platinum with wedding bells and Tiffany boxes, the truth is that platinum is actually an industrial metal – more than one-third of all platinum used is put into catalytic converters.

Which is where platinum’s cheaper neighbor, gold, comes in.

Gold shares some, but not all, of the pollution cleansing benefits of platinum. And with gold prices substantially lower than platinum, more and more people have been looking for ways to swap out platinum for gold.

On December 10, the World Gold Council – which is always looking for ways to boost demand for gold – announced a partnership with a U.S.-based company called Nanostellar to use nanotechnology to create a gold alloy that will allow gold to edge into the catalytic converter market. In fact, Nanostellar says that its new alloy can reduce emissions up to 40 percent more than pure platinum catalysts for a lower cost...

Nanostellar’s chief executive, Pankaj Dhingra, claims the company’s tests show that its gold alloy, called NS Gold, reduces carbon monoxide and hydrocarbon emissions in diesel engines by up to 40 percent more than pure platinum catalysts. Dhingra also said its use as an auto catalyst “could lead to an increase in industry demand for gold, which in 2006 totaled 16.1 million ounces (458 tons).”

James Burton, the chief executive of the World Gold Council, said the council is delighted to play its part in helping to bring the first gold-containing auto catalyst products to the market.
