Over 8 billion tons of plastics have been produced since 1950, with around 80% ending up in landfills or natural environments, causing significant contamination.
Photocatalysis is highlighted as a promising method for recycling plastic waste, as it operates at mild conditions, using solar light to convert plastics into valuable chemicals and fuels.
The text reviews recent advancements in photocatalytic plastic upcycling, discussing different types of photocatalysts and their advantages/disadvantages, along with future challenges and opportunities in this field.
