Abstract: ZnFe2O4 photocatalysts, known for narrow band gap, stable photochemical properties, and non-toxic composition, show great potential in the degradation of pollutants. In this study, spinel ZnFe2O4 nanoparticles were synthesized via a co-precipitation method, using blast-furnace slag from steelworks serving as the raw material, highlighting the value of industrial waste recycling. The optimal synthesis conditions for ZnFe2O4 were determined based on the photocatalytic degradation efficiency of Rhodamine B (Rh B). Subsequently, the optimized ZnFe2O4 nanoparticles were employed for the photocatalytic degradation of phenol in simulated wastewater. The results indicate that the photocatalytic performance of ZnFe2O4 nanoparticles, obtained by calcination at 650 °C for 2 h under the condition of a mass ratio of acid solution to blast-furnace slag of 9:1 and a reaction time of 8 h, is superior. Under strong acidic conditions (pH = 1), the photocatalytic degradation rate of phenol reached 97.7% within 2 h. After five consecutive cycles, the material exhibited excellent photochemical stability, preserving its structural and functional integrity. Furthermore, the photocatalytic degradation efficiency of phenol was found to be 72.0% within 2 h. Based on the catalytic mechanism analysis, the active species sequence during the degradation of pollutants by ZnFe2O4 nanoparticles is as follows: ·O2− > ·OH > e− > h+, suggesting that superoxide radicals (·O2−) and hydroxyl radicals (·OH) play dominant roles in the pollutant degradation.
