Preparation of porous carbon with zinc oxide template

摘要

The porous carbon materials were prepared by the following processes of evaporation induction self-assembly (EISA), thermal polymerization process and calcination step at high temperature with the nano-zinc oxide as a hard template and phenol resin as carbon source. The as-prepared porous carbon materials were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), N_2 adsorption/desorption isotherms (BET) and Fourier transform infrared spectroscopy (FT-IR). The adsorption performance was investigated via removal ciprofloxacin antibiotic. The results showed that the more the amount of zinc oxide template was added in the prepared process of porous carbon, the clearer pore channel of as-prepared porous carbon was exhibited. When the dosage of zinc oxide reach 0.4 g, it is well formed a preferably porous carbon, the higher adsorption rate of ciprofloxacin with 100 mL of 15 mg/L could reach 71.2%.
