Scalable synthesis of Bi2O2S nanoplates with large piezoelectric potential induced by built-in electric field in [Bi2O2]2+ layer for degradation of organic contaminants

2D piezoelectric catalysts with strong piezoresponse and high piezoelectric potential have valuable applications in catalytic degradation of organic pollutants and antibiotics, but the development of novel nanomaterials with powerful piezopotential still remains a serious challenge. Bismuth oxysulfide (Bi
