Plastic photoreforming offers a compelling technology to address the global issue of the large amount cumulative plastic waste by converting it into valuable fuels and chemical feedstocks. However, constrained by insufficient mass and energy transfers, the existing hydrophilic plastic photoreforming systems heavily rely on the unsustainable chemical pre-treatments in corrosive solutions. Herein, we demonstrate a conceptual plastic photoreforming system based on a floatable hydrophobic organic-inorganic hybrid-TiO2 photocatalyst, which unlocks superoxide radical as the major oxidizing species and forms a four-phase interface among photocatalyst, plastic substrate, water and air, thus greatly enhancing the mass and energy transfers. Consequently, the photoreforming yield rates in neutral aqueous solutions are increased by 1–2 orders of magnitude for typical plastic including polyethylene, polypropylene, and polyvinyl chloride without applying pre-treatments, whilst producing high-value C2H5OH with a selectivity of over 40%. We believe this work reveals a feasible route to sustainable plastic photoreforming. Plastic photoreforming offers a promising route for recycling plastic waste but typically depends on unsustainable, corrosive conditions. Here, the authors present a floatable organic–inorganic hybrid TiO2 material that enables efficient conversion of common plastics such as PE, PP, and PVC under neutral conditions.

Probing Metal/High-Entropy Perovskite Heterointerface for Efficient and Sustainable CO2 Electroreduction Solid oxide electrolysis cells (SOECs) are increasingly recognized for their great potential in carbon dioxide reduction reaction (CO2RR). However, the sluggish kinetics of CO2RR impedes their widespread commercialization. Here, a novel in-situ formed metal/high-entropy perovskite heterointerface, [email protected]δ (SFVMNT), is proposed to enhance CO2RR.

AbstractA key factor contributing to resistance in immune checkpoint blockade (ICB) therapies is CD8+ T-cell tolerance in the tumor microenvironment (TME), partly resulting from upregulating coinhibitory receptors. Here, we describe the role of PGRN as a coinhibitory molecule that modulates the antitumor response of CD8+ T cells, thus presenting a novel immunosuppressive target for lung cancer.
