Insights into the enhanced electrochemical sensing behavior of hydroquinone and catechol simultaneously enabled by ultrafine layer CoP–NiCoP heterostructure on graphene frameworks

We have synthesized ultrafine CoP–NiCoP heterojunction nanosheets with GFs as supporter (defined as CoP–NiCoP/GFs). The developed electrochemical sensor based on CoP–NiCoP/GFs could realize the simultaneous detection of hydroquinone and catechol.
