Optimization of photocatalytic performance of ammonium metavanadate doped high titanium blast furnace slag

In order to realize the comprehensive utilization of high titanium type blast furnace slag by non-extracting titanium method, the high titanium type blast furnace slag doped with ammonium metavanadate was used as raw material for preparing photocatalyst, the effects of calcination temperature, doping amount and calcination time on the degradation rate of simulated pollutant Methylene blue solution were investigated under ultraviolet light, the catalyst was characterized by XRD. The results showed that the degradation rate of the doped photocatalyst reached 83.5% at 800 °C, 45% of ammonium metavanadate-TiO2 and 2h, and the degradation rate was increased by 26.9% compared with that before doping.
