Built-in electric field driven S-scheme Bi 2 O 2 CO 3 /Bi 5 O 7 Br heterojunction for superior photocatalytic mineralization of polystyrene microplastics
AI summary Read the abstract
A bismuth-based S-scheme heterojunction photocatalyst with a built-in electric field was engineered to enhance charge separation and achieve superior photocatalytic degradation of polystyrene microplastics under light irradiation. This approach demonstrates a promising pathway for direct destruction of persistent microplastic pollutants using solar-driven catalysis.
The Bi 2 O 2 CO 3 /Bi 5 O 7 Br S-scheme heterojunction was prepared, which improved the mobility of photogenerated charges and effectively degraded polystyrene microplastics.
