▎ 摘　　要

NOVELTY - A zinc oxide-doped reduced graphene oxide-doped polypyrrole nanocomposite comprises zinc oxide nanorods, reduced graphene oxide film uniformly coated on the surface of the zinc oxide nanorods, and polypyrrole film uniformly distributed on the surface of the reduced graphene oxide film. USE - Zinc oxide-doped reduced graphene oxide-doped polypyrrole nanocomposite for detecting mercury ions in seawater (claimed). ADVANTAGE - The zinc oxide-doped reduced graphene oxide-doped polypyrrole nanocomposite has mild reaction condition, better stability and synergy with certain complex seawater environment interference resistance capability, and can be prepared in simple and cost effective manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing a zinc oxide-doped reduced graphene oxide-doped polypyrrole nanocomposite.
