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 sought throughout 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 years in the Bible. Not only 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 imagined by those ancient mystics, scientists in China may be about to make this dream a reality. No, they haven’t discovered the key to eternal life – that was someone else – but they have found a way 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 structure. “Frozen” at zero valence by this process, the copper became less reactive and started behaving instead like noble metals such as gold or silver.

The process makes copper oxidization-resistant even at high temperatures, "similar to a warrior with a solid armor resisting the attack on the battlefield." SUN Jian and YU Jiafeng

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