The green circular utilization of waste plastics is crucial for environmental protection. Converting waste plastics into H-2 fuel and valuable chemicals by utilization of the solar spectrum is highly attractive. Herein, a photothermal catalyst composed of metallic NiCo2S4 and semiconductor ZnxCd1-xS (NCS-ZCS) materials is rationally designed. The photogenerated electrons are shown to flow from ZnxCd1-xS to NiCo2S4 and are excited into hot electrons via the localized surface plasmon resonance effect, promoting H-2 evolution. The holes on ZnxCd1-xS serve as the oxidation active species for efficiently converting waste plastic into value-added chemicals. Systematic studies show that the photoreforming process can be enhanced with a photothermal effect from NiCo2S4. Theoretical calculations confirmed experimental results. Under visible to infrared irradiation, H-2 evolution rates of 57.0 and 106.0 mmolg(cat)(-1)h(-1) along with the yields of value-added chemicals of 39.18 and 206.05 mu mol mL(-1) in polyethylene terephthalate and polylactic acid substrates are achieved.
