Plasmonic photocatalysis: complete degradation of bisphenol A by a gold nanoparticle-reduced graphene oxide composite

Abstract:
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 photocatalytic 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.

Classifying Matter by Composition
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures.
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated.
A mixture is composed of two or...
