因为低费用,相对安全,和环境友好, Visible-light-initiated 器官的转变收到了许多注意。在这个工作,也就是,我们在 visible-light-driven 光催化剂的一种新奇类型上报导 CdS-nanoparticle-decorated 金属器官的框架( MOF )的多孔的 nanocomposites ,由多孔的 MIL-100 ( Fe )在用作支持和镉醋酸盐的一个简单 solvothermal 方法准备了( Cd (交流)2)作为 CdS 先锋。当到 benzaldehyde 的本甲基酒精的选择氧化被用作探查反应时,结果证明 MIL-100 (Fe ) 和 CdS 半导体罐头的联合显著地在房间温度提高 photocatalytic 效率,作为与纯 CdS 的相比。提高的 photocatalytic 表演能由于 MIL-100 (Fe ) 的存在被归因于提高的轻吸收, photogenerated 电子洞对的更有效的分离,和 CdS 的增加的表面区域的联合效果。这个工作在太阳能的变换的域里为应用程序表明那条基于 MOF 的合成材料抓住伟人诺言进化学能。
Visible-light-initiated organic transformations have received much attention because of low cost, relative safety, and environmental friendliness. In this work, we report on a novel type of visible-light-driven photocatalysts, namely, porous nanocomposites of CdS-nanoparticle-decorated metal-organic frameworks (MOF), prepared by a simple solvothermal method in which porous MIL-100(Fe) served as the support and cadmium acetate (Cd(Ac)2) as the CdS precursor. When the selective oxidation of benzyl alcohol to benzaldehyde is used as the probe reaction, the results show that the combination of MIL-100(Fe) and CdS semiconductor can remarkably enhance the photocatalytic efficiency at room temperature, as compared to that of pure CdS. The enhanced photocatalytic performance can be attributed to the combined effects of enhanced light absorption, more efficient separation of photogenerated electron-hole pairs, and increased surface area of CdS due to the presence of MIL-100(Fe). This work demonstrates that MOF-based composite materials hold great promise for applications in the field of solar-energy conversion into chemical energy.
