Enhanced degradation of polyethylene terephthalate plastics by CdS/CeO2 heterojunction photocatalyst activated peroxymonosulfate
AI summary Read the abstract
Scientists developed a photocatalytic system using cadmium sulfide and cerium oxide that can break down PET plastic waste with remarkable efficiency, achieving over 93% weight loss. The process works by activating a chemical oxidant under light, generating reactive species that decompose the plastic. This research points toward a potentially scalable method for recycling one of the most common plastic types found in bottles and packaging.
Waste plastics have posed enormous to the environment, but their recycling, especially polyethylene terephthalate plastics, was still a huge challenge. Here, CdS/CeO was used as the photocatalyst to promote the degradation of PET-12 plastics by activating peroxymonosulfate (PMS) synergistic photocatalytic system. The results showed that 10 % CdS/CeO had the best performance under the illumination condition, and the weight loss rate of PET-12 could reach 93.92 % after adding 3 mM PMS. The effects of important parameters (PMS dose and co-existing anions) on PET-12 degradation were systematically studied, and the excellent performance of the photocatalytic-activated PMS system was verified by comparison experiments. SO contributed the most to the degradation performance of PET-12 plastics, which was demonstrated by electron paramagnetic resonance (EPR) and free radical quenching experiments. Furthermore, the results of GC showed that the gas products including CO, and CH. This indicated that the mineralized products could be further reduced to hydrocarbon fuel under the action of the photocatalyst. This job supplied a new idea for the photocatalytic treatment of waste microplastics in the water, which will help recycle waste plastics and recycle carbon resources.

Scientists created a photocatalyst using recycled plastic bottles (PET) and used it to break down polystyrene microplastics in water under visible light, achieving 90% degradation within 30 hours. The approach cleverly uses plastic waste as both a raw material and a target, turning one pollution problem into a tool for solving another. This proof-of-concept suggests a potentially scalable method for removing microplastics from water using sunlight-driven chemistry.

Photoelectrochemical Reforming of PET Plastics using a Ternary CoOCl/SrTiO 3 /TiO 2 Heterojunction Membrane Electrode
AI summary Read the abstract
Scientists have developed a new material that uses sunlight to break down PET plastic (the kind used in water bottles) into useful chemicals and clean hydrogen fuel, instead of letting it pile up in landfills or break into microplastics. This matters because less plastic waste means fewer microplastics ending up in our water, food, and eventually our bodies, where they've been linked to potential health concerns. While this is still early-stage lab research, it points toward a future where plastic recycling could also help produce clean energy.
