Abstract

N-rich carbon nitride (CN) is a promising framework that can generate innovative hybrid structures for energy applications. However, the low thermal stability of N atoms in the CN matrix is a major drawback as the crystallization of the hybridized counterpart requires a high temperature. Herein, we report the successful synthesis of the hybrid of N-rich CN and Fe1-xS at 700 °C by constructing a stable C−N−Fe−S heterointerface using a Fe-incorporated metal-organic framework (MOF) and dithiooxamide containing C, N and S atoms. The hybrids display promising capacities toward Li+ and Na+ ions storage, highlighting the beneficial role of N-rich CN on battery performance. By systematically investigating their structure and electrochemical properties, we show that N-rich CN, along with the heterointerface, not only acts as a hybridization matrix that helps facilitate the charge transfer kinetics but also generates substantial capacity. This unique study reveals a powerful platform for the rational design of N-rich CN based hybrids from MOF.
