Abstract: ZIF-67 derived carbon material catalyst is prepared by pyrolysis method using ZIF-67 as the precursor.The catalyst is characterized by BET,XRD,SEM and other analytical methods.The results show that the catalysts prepared at 700℃,800℃ and 900℃ all form elemental Co,and forming a structure of nitrogen-doped porous carbon coated with cobalt metal.Through comparative experiments,it is found that the catalyst prepared at 800℃ has higher catalytic activity than that prepared at 700℃ and 900℃.An experiment is designed for catalytic degradation of simulated phenol wastewater,and the results show that the removal rates of phenol and TOC are 90.6% and 82.3%,respectively when the initial mass concentration of phenol is 50 mg·L-1,the concentration of persulfate is 1.2 mmol·L-1,the mass concentration of catalyst is 0.05 g·L-1,pH=9 and the reaction lasts for 120 min.After the catalyst has been used for 5 times,the removal rates of phenol and TOC are 76.4% and 70.3%,respectively.
