A mesoporous ZnIn₂S₄ photocatalyst shows notable activity for photoreforming of PLA, PET and PU to generate small organic chemicals and H₂ fuel under simulated sunlight at room temperature.

A biomimetic catalytic approach for the aerobic oxidation of C–sp(3)–H bonds using galactose oxidase model compound was developed. EPR showed that the Cu^I-radical intermediate species was critical for O₂ activation.
