三金属-碳复合材料的制备及其在工业废水催化臭氧氧化中应用
Preparation of trimetal-carbon composites and their application in catalytic ozonation of industrial wastewater
摘要
Abstract
Advanced oxidation processes(AOPs)hold great promise for water treatment due to their high efficiency in degrading organic pollutants.In particular,heterogeneous catalytic ozonation(HCO)has garnered significant attention for its potent oxidation capability,strong anti-interference capacity,and minimal secondary pollution.In this study,a series of trimetallic-carbon composite ozone catalysts were prepared using γ-Al2O3 as the support via an organic precursor pyrolysis method.This strategy effectively enhanced the catalytic activity and mechanical strength of the catalysts while mitigating the typical drawbacks of carbon materials(low mechanical strength)and metal-based catalysts(poor mass transfer efficiency).Experimental results revealed that the Fe,Co,and Cu trimetallic composite catalyst with carbon and alumina(CA-FeCoCu)demonstrated superior performance in degrading phenol and treating actual industrial wastewater.Characterization analysis indicated that the synergistic interaction among the three metals and the introduction of multiple types of carbon materials significantly increased the specific surface area of the catalyst and promoted the generation of hydroxyl radicals(·OH).In pilot-scale fixed-bed reactions,the CA-FeCoCu/O3 system reduced COD from 120 mg·L-1 to below 40 mg·L-1 with an O3 consumption ratio(O/C)of less than 1,indicating effective operational costs.This study proposes a novel strategy fordesigning efficient and stable heterogeneous ozone catalysts and offers valuable insights for the practical implementation of HCO technology in industrial wastewater treatment.关键词
