Abstract

The pollutants degradation rate of iron ore tailings–based heterogeneous catalysts is the main factor limiting its application. Herein, an iron ore tailings–based Fenton-like catalyst (I/W(3:1)-900-60) with a relatively fast catalysis rate was constructed by co-pyrolysis (900°C, 60 min holding time) of iron ore tailings and wheat straw with a mass ratio of 3:1. With wheat straw blending, the generated I/W(3:1)-900-60 presented a larger surface area (24.53 m2/g), smaller pore size (3.76 nm), reduced iron species (Fe2+ from magnetic), and a higher catalytic activity (0.0229 min−1) than I-900-60 (1.32 m2/g, 12.87 nm, 0.012 min−1) pyrolyzed using single iron ore tailing under the same pyrolysis conditions. In addition, biochar and iron ore tailings in I/W(3:1)-900-60 were tightly combined through chemical bonding. The optimal catalyst remains active after three cycles, indicating its catalytic stability and recyclability. The good Fenton-like methylene blue degradation efficiency of I/W(3:1)-900-60 was ascribed to the sacrificial role of biochar, as well as the electron transfer between biochar and iron active sites or the redox cycles of ≡Fe3+/Fe2+. This finding provides a facile construction strategy for highly active iron ore tailings–based Fenton-like catalyst and thereby had a great potential application in wastewater treatment.
