Zusammenfassung: | Bisphenol A is a well-known endocrine disruptor that comes from plastic/epoxy resin-based consumer products, pollutes our environment and is responsible for various human diseases. Thus, its removal from water/food/the environment is becoming a challenging issue. Here we report the visible light photo-catalytic degradation of bisphenol A using a gold nanoparticle based composite with reduced graphene oxide. The nanocomposite captures visible light and produces hydroxyl radicals that oxidize bisphenol A into smaller organic fragments such as phenol derivatives and aliphatic aldehydes/ketones. The composition of the nanocomposite has been optimized for most efficient degradation of bisphenol A under visible light and the approach may be extended for the sunlight-based removal of bisphenol A from water/food/the environment. |
