3D Biomass‐Derived Carbon Materials for Electrochemical Biosensors

3D biomass‐derived carbon (3D‐BC) materials are widely developed for various electrochemical sensors due to their structural diversity and high electrical conductivity, and are gradually experiencing their most prosperous moment. A timely and comprehensive review of structure‐strategy‐property will greatly broaden this research field. In this paper, the mechanism of biomass‐derived carbon conversion is presented and the recent progress of 3D‐BC materials for constructing high‐performance electrochemical sensors, including biomass sources, carbonization methods, and synthesis strategies for 3D‐BC is summarized, as well as their applications in different electrochemical sensors are reviewed. Finally, the challenges and opportunities for the future development of biomass‐derived carbon (BC) materials are emphasized. In conclusion, this review will assist researchers in selecting suitable precursors and strategies to design BC materials and facilitate their application in future electrochemical sensors.
