Scientists Have Discovered A Way To Turn Copper Into Gold (Well, Sort Of)

Long before it was rescued from the clutches of He Who Must Not Be Named by a bespectacled British 11 -year-old, the Philosopher’s Stone was an ancient and mystical substance tried in all regions of the world for its miraculous and life-giving properties.

Legend said the Stone held the key to immortality- some believed it was the reason Adam and Eve were able to live for over 900 times in the Bible. Not simply that, but it was said to be capable of chrysopoeia- the ability to transform base metals into pure gold.

Now, thousands of years after it was first supposed by those ancient mystics, scientists in China may be about to make this daydream a reality. No, they haven’t discovered the key to eternal life- that was someone else– but they have found a style to turn copper into a new material “almost identical” to gold.

In their paper, published this week in Science Advances, the team describe how they bombarded copper atoms with high-energy argon plasma, changing the metal’s electron arrangement. “Frozen” at zero valence by this process, the copper became less reactive and started behaving instead like noble metals such as amber or silver.

The copper nanoparticles “achieved catalytic performance extremely similar to that of amber or silver, ” the team explained in a statement posted on the academy’s website and reported in the South China Morning Post. “The ensues … proved that after processing, metal copper can transform from’ chicken’ to’ phoenix.’”

Unlike the alchemical solutions sought by Isaac Newton, among others, this breakthrough won’t attain the chemists abruptly and inexplicably wealthy- it can’t be used to attain fake gold. But that hasn’t stopped some commenters from speculating that the development might lead to the precious metal losing its place as a stock market and economic hedge criterion- perhaps to an electronic alternative such as Bitcoin.

But cryptocurrencies, with their current planet-destroying energy demands, are about as far from the researchers’ purposes as possible. They instead visualize their discovery as an essential- and lucrative- lane to take on the challenges of the modern world.

Not only do their opposition to oxidization and low reactivity make gold and silver perfect for industrial uses- there’s a veritable jewelry container inside your smartphone, for example- noble metals are also used in sophisticated chemical procedures that can transform coal into useful and clean resources like ethanol.

“The clean utilization of coal the resources necessary synthesize high value-added compounds is greatly desired with the increasing energy and environmental problems, ” explains the paper.

“[ Methyl glycolate] … is an essential intermediate with higher commercial price than[ other substances] for the synthesis of pharmaceutical products, fine chemicals, and perfumes. Nonetheless,[ methyl glycolate] is difficult to be gained via copper catalysts …[ so] the development of an efficient catalyst to control and regulate the target products is still a great challenge for both academia and industry.”
