In this study, TiO/MSGM composite material with adsorption-photocatalytic properties was prepared by extracting mesoporous silica glass microsphere (MSGM) from coal gasification fine slag (CGFS) as a novel TiO carrier. The results of characterization and properties of the composite showed that MSGM could improve the adsorption capacity and photocatalytic activity of the composite by improving the pore structure of the composite, hindering the growth of TiO particles, increasing the phase transition temperature of TiO, enhancing the dispersion of TiO particles. The sample 1:3-TiO/MSGM-2-500 prepared under the optimized conditions possesses satisfactory morphology characteristics, high adsorption capacity, and photocatalytic activity to rhodamine B (RhB). The synergistic effects of adsorption and photocatalytic significantly increase the total removal rate of RhB. This study not only provides a new direction for high-value-added resource utilization of CGFS but also gives a new kind of low-cost carrier material with adsorption property for TiO loading to remove organic dye pollutants.
在本研究中，通过从煤气化细渣（CGFS）中提取介孔硅玻璃微球（MSGM）作为新型 TiO 载体，制备了具有吸附-光催化性能的 TiO/MSGM 复合材料。复合的表征和性能结果表明，MSGM 通过改善复合的孔结构、阻碍 TiO 颗粒的生长、提高 TiO 的相转变温度、增强 TiO 颗粒的分散性，可以提高复合的吸附能力和光催化活性。在优化条件下制备的样品 1:3-TiO/MSGM-2-500 具有令人满意的形态特征、高吸附能力和对罗丹明 B（RhB）的光催化活性。吸附和光催化的协同作用显著提高了 RhB 的总去除率。本研究不仅为 CGFS 的高附加值资源利用提供了新方向，还为负载 TiO 去除有机染料污染物的具有吸附性能的新型低成本载体材料提供了新途径。
