Fig. 1

Schematic illustration of contact between catalyst and LDPE in a, traditional photocatalytic recycling and c, photothermal recycling. b EDX maps of cross-sectional SEM image for a physical mixture of a LDPE granule and Ru/TiO2 sample (state likes traditional photocatalytic LDPE recycling). Scale bar, 100 μm. d EDX maps of cross-sectional SEM image for a quenched molten LDPE-Ru/TiO2 sample (state likes photothermal LDPE recycling). Scale bar, 5 μm. e Pristine LDPE and molten LDPE droplet contact angles on a glass substrate coated with Ru/TiO2 at various temperatures in an argon (Ar) atmosphere.
