Photothermal catalysis of waste plastics into propionic acid and hydrogen via Ni single-atom site isolation effect

Proceedings of the National Academy of Sciences, Volume 122, Issue 26, July 2025.
SignificanceThis study presents a solar-driven photothermal catalytic method for converting polyethylene waste into propionic acid and hydrogen under ambient conditions. Using atomically dispersed Ni sites on CeO2, we achieved a 1.6 times higher propionic …
