“…Very recently, Pan, Xu and coworkers developed a photothermal reaction using tetrabutylammonium decatungstate (TBADT) as the photocatalyst, which installing diisopropyl azodicarboxylate (DIAD) onto PE under sunlight irradiation (Scheme 8b) [25] . Under the optimal conditions, LDPE ( M n =29.1 kg/mol, Ð =3.63) could give DIAD‐PE ( M n =6.1 kg/mol, Ð =2.25) with DOF of 7.14 mol %.…”

Polyolefins consist of abundant hydrophobic C−C and C−H bonds, and are considered as immensely potential untapped resources. Chemical upcycling offers a convenient and promising recycling strategy of polyolefins to produce newly‐functionalized polymeric materials, and high‐value added chemicals. The significant progress made in C–H functionalization reactions of alkane molecules provides new opportunities for improving polyolefin treatments. This review focuses on recent advancements in post‐modification routes, specifically the introduction of C–C and C–X (X = O, N, S, halogens and etc.) bonds onto polyolefin chain backbones, as well as degradation models involving homogeneous C–H functionalization. By emphasizing these developments, we aim to highlight the potential of chemical upcycling for enhancing the treatment of polyolefins.

“…The result indicates the obvious merits of photothermal catalysis compared with the conventional photocatalysis in terms of efficiency of plastic upcycling. Pan et al [ 42 ] realized an efficient and unique recycling of PE through a photothermal C–H activation and modification synergy ( Figure a). They grafted the diisopropyl azodicarboxylate (DIAD) onto the PE backbone under sunlight at 110 °C using tetrabutylammonium decatungstate (TBADT) as the photocatalysts.…”

The increasingly massive accumulation of plastic waste is triggering a global pollution crisis, causing severe economic and health issues. As an effective strategy to realize synchronous environmental remediation and value‐added chemical production, the catalytic upcycling of plastics has received extensive attention. Among the upcycling approaches, the emerging photothermal catalysis outstands with features of high conversion efficiency and mild reaction conditions. Herein, the advancements of photothermal catalysis in plastic waste upcycling are reviewed for the first time. The general limitations of the traditional thermocatalytic and photocatalytic upcycling of plastics are first discussed. Subsequently, the photothermal catalytic approaches to upcycling of plastics are classified into three categories depending on the catalytic mechanism, and discussed in depth. Finally, the current challenges in the field are appraised, and several suggestions concerning the investigation of the mechanisms and practical applications for the conversion of plastics into valuable chemicals are highlighted.
