This article reviews the research progress of coffee grounds-based carbon materials in various fields such as water purification, photocatalytic degradation, supercapacitors, and detection probes. Coffee grounds, as an important agricultural byproduct, have rich carbon content and porous structure, which can provide high-quality sources for the preparation of various carbon materials with special purposes. Research has shown that coffee grounds-based biochar and activated carbon have good water purification performance. Through their rich pores and functional groups, they can effectively adsorb pollutants in water. In addition, the material of carbonized coffee grounds has also demonstrated excellent performance in applications such as photocatalytic degradation, supercapacitors, and detection probes. These research findings provide important references for further development and utilization of coffee grounds.
