ZIF-67@Yeast was synthesized with in-situ growth procedure by using hydrothermally carbonized yeast as the substrate material. The prepared ZIF-67@Yeast was characterized in detail by SEM, BET, XRD and TG analysis. In addition, the adsorption properties of Pb2+ by ZIF-67@Yeast were also investigated. The results show that the adsorption capacity of Pb2+ by ZIF-67@Yeast is larger than the sum of the adsorption capacity of Pb2+ by individual yeast and ZIF-67. Yeast could maintain a stable morphology after hydrothermal carbonization at 180 °C. Therefore, many MOFs synthesized by hydrothermal or microwave methods at 180 °C could also be compounded with Yeast as a base material. This provides more possibilities that heavy metal ions are adsorbed by the synthesis of more diverse MOFs composites. ZIF-67@Yeast was synthesized by in situ growth using a hydrothermally carbonized yeast as a substrate material, which can maintain a stable morphology and efficient removal of Pb2+ in water. Image 1 • ZIF-67@Yeast was synthesized by using a hydrothermally carbonized yeast as a substrate material. • The adsorption capacity of Pb2+ by ZIF-67@Yeast is larger than that of Pb2+ by individual yeast and ZIF-67. • Many MOFs could also be compounded with yeast as a base material.
