Using titanium-containing furnace slag as the raw material,a submicron sheet-like silicon-based titanium dioxide photocatalyst was synthesized by hydrothermal-acidification-calcination process.The effects of acid hydrolysis reaction concentration,acid hydrolysis reaction time,photocatalyst dosage,and light conditions on the catalytic performance were studied.The results showed that when the acid hydrolysis concentration was 1.2mol/L,the acid hydrolysis reaction time was 5h,and the amount of photocatalyst was 20mg,the methylene blue degradation rate was up to 97.28% after 60min under UV irradiation,and the methylene blue removal rate was up to 77.85% after 120min under visible light irradiation.
