Abstract With the continuous development of industry, problem water pollution is becoming increasingly serious. Methylene blue (Mb) an important pollutant that has a negative impact on ecosystems. Photocatalytic technology been recognized as effective and environmentally friendly method for solving pollution, which attracted widespread research attention. This study providing solid experimental theoretical basis high value. In this paper, MnTiO 3 with different molar ratios (Mn:Ti = 1:0.9 1:1) calcination temperatures (800, 900, 1000 °C) was synthesized by sol–gel method. A systematic conducted structure, photodegradation performance, mechanism synthetic materials. Research shown when Mn:Ti ratio temperature °C/2 h, pure phase can be obtained. Among them, MnTi 0.9 O ‐900 h sample composed , TiO 2 Mn phases showed highest photocatalytic degradation efficiency (54.3%) towards Mb. The excellent activity due to its narrow bandgap, porous abundant oxygen vacancies, heterojunction enhances light absorption improves electron hole separation efficiency.
