Description
Qikun Hu and colleagues recycled polyethylene plastic chemically in two thousand twenty-four. Breaking plastic down with hydrogen yields fuels and waxes. High hydrogen pressure usually suppresses unwanted methane gas. Their catalyst mixes a little ruthenium into platinum. This dilute alloy changes where bonds break. Plastic sticks to both metals on the surface.
Bond cutting runs faster on ruthenium sites. Isolated sites prevent repeated end-cutting of fragments. Methane stayed very low even at ambient pressure. Fuels and lubricant oils formed instead. Low-pressure hydrogen sources could feed such plants locally. Decentralized plastic upcycling becomes more feasible. Spectroscopic studies backed the mechanism proposed.
