摘要

研究人员获得了固定在整体二氧化硅气凝胶中的 gC3N4 颗粒的复合材料,并研究了其物理化学光催化性能。这种复合材料可以多次重复使用。在超临界二氧化碳(SC-CO2)中用分子氧氧化烷基芳基硫化物时,它们比游离 gC3N4 表现出更高的光催化活性。这项研究成果可作为开发高效有机化合物氧化工艺的基础。

Composites of Graphitic Carbon Nitride with Silica Aerogel: Recyclable Immobilized Photocatalysts for Sulfide Oxidation with Oxygen in SC-CO2

Composites of gC3N4 particles immobilized in monolithic silica aerogel have been obtained, and their physicochemical photocatalytic properties were studied. The composites may be reused many times. They showed higher photocatalytic activity than free gC3N4 in the oxidations of alkyl aryl sulfides with molecular oxygen in supercritical carbon dioxide (SC-CO2). The results presented in this work can serve as a basis for the development of efficient processes of organic compounds oxidation.
