文摘

Ultrahigh sensitive voltammetric sensor for Cu (II) detection based on carbon nitride was firstly achieved. Ultrathin carbon nitride with large amount of oxygen was firstly prepared. Role of oxygen abundance in enhancing the sensitivity was clarified. Cu (II) sensing mechanism of the sensor was firstly elaborated.
