Abstract

Abstract

In order to realize the comprehensive utilization of high-titanium blast furnace slag without titanium extraction, cobalt doped photocatalyst was prepared via liquid phase method followed by sintering using Pangang high-titanium blast furnace slag and cobalt nitrate as raw materials. The influences of calcination temperature, Co doping amount and calcination time on the degradation rate of simulated pollutant methylene blue solution were investigated under ultraviolet light. The results show that the degradation rate of 89.0% can be obtained for the Co-doped photocatalyst roasted at 600 °C for 2 h with mass ratio of Co to Ti of 0.03, 32.4% higher than that of the photocatalyst without Co doping.
