An acrylic acid emulsion mixture is used for synthesis of novel porous silica (E-Si) material. The photocatalytic activity of TiO2 under solar light irradiation for isoproturon (herbicide) degradation is drastically increased when dispersed over E-Si support using solid state dispersion (SSD) technique. The composite material is characterized by XRD, nitrogen adsorption-desorption isotherms, UV-vis DRS, SEM and TEM measurements. The photocatalytic activities of the composite catalysts are evaluated for different parameters. The 5 wt% TiO2/E-Si is found to be highly active for isoproturon degradation.
一种丙烯酸乳液混合物用于合成新型多孔二氧化硅（E-Si）材料。采用固态分散（SSD）技术将 TiO2 分散在 E-Si 载体上，可显著提高 TiO2 在太阳光照射下对异噁草松（除草剂）的光催化活性。通过 XRD、氮气吸附-脱附等温线、UV-vis DRS、SEM 和 TEM 测量对复合材料进行了表征。评估了复合材料催化剂在不同参数下的光催化活性。发现 5wt%TiO2/E-Si 对异噁草松的降解具有很高的活性。
