Porous carbon has a large specific surface area, controllable porosity and excellent thermal stability, porous carbon have attracted considerable attention in various research fields. In this work, we prepared polyphenol-derived carbon from Tannin-Zn based hydrogel. First, tannic acid and ZnCl2 are dissolved in water and thermally treated by hydrothermal method. After that, it is dried on the hot plate and carbonization process was performed to obtain polyphenol derived carbon. and porous was produced. we also focused on polyphenol derived carbon with different porosity. Before the hydrothermal process, tannic acid – ZnCl2 sample was added with NaOH to raise the pH value. NaOH acts as a stabilizer to assist metal chelating. After that, carbonization was carried out to obtain carbon with different porosity. The detailed preparation and characterization of polyphenol derived carbon composite will be discussed in the conference. |
