| 中文摘要: |
| 针对高活性Cu基团簇(Cu cluster)催化剂的稳定性问题, 利用MOFs材料独特的结构限域作用, 将Cu团簇锚定在UiO-66中, 构建了Cu cluster@UiO-66复合材料, 改善了催化剂的稳定性和催化活性. 在该复合结构中, UiO-66不仅可作为吸光单元捕获太阳光形成光生载流子, 而且UiO-66的多孔结构可以有效稳定Cu团簇, 保证其微观尺度上的高度分散和结构稳定. 研究发现, 在光催化反应过程中, UiO-66的光生电子可快速转移至Cu团簇, 进而以Cu团簇作为催化活性位点驱动CO2还原反应. 得益于复合材料中高效的电荷转移和稳定的团簇活性位点结构, 光催化CO2加氢反应活性明显增强. 本研究为合成MOFs负载型团簇材料提供了新的思路. |
| 英文摘要: |
| Aiming at the stability of highly active Cu-based cluster catalysts, we constructed the Cu cluster@UiO-66 composite by using the unique structural confinement effect of MOFs to anchor the Cu in UiO-66 can not only act as a light-absorbing unit to capture sunlight to form photogenerated carriers, but also enhance the porous structural stability on the microscopic scale. It is found that during the photocatalytic reaction, the photogenerated electrons of UiO-66 can be rapidly transferred to the Cu cluster, which is used as the catalytically active site to drive the CO2 reduction reaction. Benefiting from the efficient charge transfer and stable cluster active site structure in the composite, the photocatalytic CO2 hydrogenation reaction activity is significantly enhanced. The related research results provide a new idea for the synthesis of MOFs-supported cluster materials. |
