摘要
本研究采用水热法和低温还原法成功制备了一系列xCu@MIL-101(Fe)的π络合CO吸附剂,克服了Cu+负载稳定且高度分散的难题。同时,利用各种表征技术深入分析了吸附剂的物理和化学性质,并利用分子动力学模拟探讨了不同金属位点对 CO 吸附的影响。结果表明,Cu+ 的加入增强了吸附剂的热稳定性,并通过竞争配位提高了 CO 的吸附性能。值得注意的是,当 Cu 的负载量达到 20 wt% 时,CO 的吸附量达到最大值 2.66 mmol/g。这项研究为开发高效、稳定、经济的 Cu+ π 复合 CO 吸附剂提供了一种新方法。
Study of Cu@MIL-101(Fe) adsorbent for the enhancement of CO adsorption: Effective Cu+ capacity and π complexation
In this study, a series of π-complexed CO adsorbents of xCu@MIL-101(Fe) were successfully prepared by hydrothermal and low-temperature reduction methods, which the objective was to overcoming the difficulties of stable and highly dispersed Cu+ loading. At the same time, the physical and chemical properties of the adsorbents were deeply analyzed using various characterization techniques, and the effects of different metal sites on CO adsorption were explored using molecular dynamics simulations. The results demonstrated that incorporating Cu+ augmented the adsorbent's thermal stability and enhanced the CO adsorption performance through competitive coordination. Notably, the CO adsorption reached a maximum of 2.66 mmol/g when the Cu loading reached 20 wt%. This study presents a novel approach for developing efficient, stable, and cost-effective Cu+ π-complexed CO adsorbents.
