摘要

结果表明，Rh-CD (cd为碳点)沉积在SiO2、Al2O3和ZrO2氧化物载体上有助于甘油转化过程中催化活性的出现。确定了丙烯醛和乙醛是该反应体系的含氧产物。研究发现，当使用比表面积较小的载体时，反应产物的产率增加，这是由于酸位表面浓度的增加引起的。

Catalytic Properties of Rh-Containing Carbon Dots on SiO2, Al2O3, and ZrO2 Oxide Supports in the Glycerol Conversion

It is shown that deposition of Rh-CD (CDs are carbon dots)onto SiO₂, Al₂O₃, and ZrO₂ oxide supports contributes to the appearance of the catalytic activity in the process of glycerol conversion. It is established that acrolein and acetaldehyde are oxygen-containing products in this reaction system. It is found that the yield of reaction products increases when using a support with a smaller specific surface area, which is caused by an increase in the surface concentration of acid sites.
