摘要
采用溶胶-凝胶法合成了纳米多面体(Co,Mn)3O4,并对其降解1,2,4-三氯苯(1,2,4-TrCB)的催化性质和机理进行研究。利用气相色谱、气相色谱-质谱联用仪等实验手段,研究了影响1,2,4-TrCB催化降解的因素。实验结果表明:175mg(Co,Mn)3O4与1.5μL 1,2,4-TrCB在300℃下反应60min,1,2,4-TrCB的降解效率达到92%,1,2,4-TrCB在催化剂表面的降解机理主要是逐级加氢脱氯。
Nano-polyhedral(Co,Mn)_3O_4was synthesized by sol-gel method,and its catalytic properties and reaction mechanism for degradation of 1,2,4-trichlorobenzene were studied in detail.The product was characterized by gas chromatography and gas chromato-graphy-mass spectrometry(GC-MS).The results showed when 200 mg nano-polyhedral Co_3O_4 reacted with 1.5μL 1,2,4-trichlorobenzene at 300℃ for 60 min,the degradation efficiency was 92%.In addition,hydrodechlorination occured dominantly during the process.
