Summary

Story summary

Researchers at King's College London and Trinity College Dublin have created cyclotrialumane, an aluminum trimer that can replace platinum and palladium catalysts.
Cyclotrialumane consists of three bonded aluminum atoms arranged in a triangle.
The molecule drives reactions similarly to platinum and palladium while remaining stable in various solvents.
Because aluminum is about 20,000 times cheaper than those metals, cyclotrialumane could lower costs for fertilizer production and automotive catalytic converters.
