[Research progress in hydrothermal carbon materials for separation and analysis]

Hydrothermal carbon materials are new functional materials prepared by the hydrothermal reaction of sugars or carbonaceous organic compounds. They have many advantages such as abundant resources of raw materials, environmental-friendliness, hydrophilicity, and easy of modify and so on. These carbon materials have been widely used as catalyst carriers, energy electrode materials, environmental adsorbents, etc. Among these, the application of hydrothermal carbon materials as absorbents reveals their ability to show strong interactions with specific molecules. In recent years, the application of these materials has been gradually extended to the field of chromatography, as stationary phases for solid-phase separation as well as for the enrichment of complex biological samples. In this paper, the recent applications of hydrothermal carbon materials for the analysis of ionic compounds, polar compounds, phosphorylated peptides, and glycopeptides are presented. Finally, the future scope of these materials in separation and enrichment is also discussed.
