ClearRecovering hydrogen from PS, LDPE and HDPE microplastics via UV-driven photolysis and TiO2-based photocatalysis
Scientists used UV light — both direct photolysis and titanium dioxide photocatalysis — to break down polystyrene, LDPE, and HDPE microplastics and capture the released hydrogen gas as a potential clean fuel.
