In order to improve the photocatalytic oxidative desulfurization (PODS) activity of TiO2, a composite of TiO2 and g-C3N4 was supported on bimodal mesoporous silica (BMMS) to synthesize TiO2-g-C3N4/BMMS. The dodecane solution of dibenzothiophene (DBT) was used as a simulated oil to evaluate the catalytic performance of the samples. The reaction conditions were optimized and the catalytic reaction mechanism was proposed. The results show that TiO2-g-C3N4/BMMS has a bimodal mesoporous structure. As an active composite, TiO2-g-C3N4 can be dispersed on BMMS. Compared to pure TiO2, the light absorption ability of TiO2-g-C3N4/BMMS is enhanced and the catalytic activity is improved. The desulfurization rate of TiO2-g-C3N4/BMMS obtained under optimized reaction conditions (i.e., the catalyst amount of 3% (in mass fraction), the molar ratio of O∶S of 10∶1, and the volume ratio of solvent to oil of 1∶1) can reach 96.6%, and the desulfurization rate remains more than 85% after 8-run repeated reactions. The main active species in the PODS process are ·O2- and h+.

为了提高TiO2的光催化氧化脱硫（PODS）活性，利用负载和复合的协同作用，将TiO2与g-C3N4复合，并负载于双介孔二氧化硅（BMMS）上，制备了TiO2-g-C3N4/BMMS。以含二苯并噻吩（DBT）的十二烷溶液为模拟油，评价了催化剂的催化性能；优化了反应条件并提出了催化反应机理。结果表明：TiO2-g-C3N4/BMMS具有明显的双介孔结构，TiO2与g-C3N4已实现复合并负载于BMMS上，TiO2-g-C3N4活性组分在载体上分散良好，与单一TiO2相比对光的吸收能力增强，催化活性有明显提高，优化后的反应条件为，催化剂用量3%（质量分数），O/S摩尔比为10∶1，萃取剂与模拟油体积比为1∶1，此时脱硫率可达96.6%，且重复使用8次后脱硫率仍保持85%以上，PODS过程中的主要活性中间物种是·O2-和h+。

摘要
收起

为了提高TiO2的光催化氧化脱硫（PODS）活性，利用负载和复合的协同作用，将TiO2与g-C3N4复合，并负载于双介孔二氧化硅（BMMS）上，制备了TiO2-g-C3N4/BMMS。以含二苯并噻吩（DBT）的十二烷溶液为模拟油，评价了催化剂的催化性能；优化了反应条件并提出了催化反应机理。结果表明：TiO2-g-C3N4/BMMS具有明显的双介孔结构，TiO2与g-C3N4已实现复合并负载于BMMS上，TiO2-g-C3N4活性组分在载体上分散良好，与单一TiO2相比对光的吸收能力增强，催化活性有明显提高，优化后的反应条件为，催化剂用量3%（质量分数），O/S摩尔比为10∶1，萃取剂与模拟油体积比为1∶1，此时脱硫率可达96.6%，且重复使用8次后脱硫率仍保持85%以上，PODS过程中的主要活性中间物种是·O2-和h+。

In order to improve the photocatalytic oxidative desulfurization (PODS) activity of TiO2, a composite of TiO2 and g-C3N4 was supported on bimodal mesoporous silica (BMMS) to synthesize TiO2-g-C3N4/BMMS. The dodecane solution of dibenzothiophene (DBT) was used as a simulated oil to evaluate the catalytic performance of the samples. The reaction conditions were optimized and the catalytic reaction mechanism was proposed. The results show that TiO2-g-C3N4/BMMS has a bimodal mesoporous structure. As an active composite, TiO2-g-C3N4 can be dispersed on BMMS. Compared to pure TiO2, the light absorption ability of TiO2-g-C3N4/BMMS is enhanced and the catalytic activity is improved. The desulfurization rate of TiO2-g-C3N4/BMMS obtained under optimized reaction conditions (i.e., the catalyst amount of 3% (in mass fraction), the molar ratio of O∶S of 10∶1, and the volume ratio of solvent to oil of 1∶1) can reach 96.6%, and the desulfurization rate remains more than 85% after 8-run repeated reactions. The main active species in the PODS process are ·O2- and h+.
