Description

一种铜掺杂ZIF-8纳米复合物的制备方法
技术领域
本发明涉及一种铜掺杂ZIF-8纳米复合物的制备方法。
背景技术
随着化石燃料的大量使用，储量日益减少，生物质作为一种洁净的可再生能源，化石燃料必将会被生物质能取代，对生物质能源的开发利用，尤其是利用生物质能能源在工业化上的利用，成为碳减排和资源再生等领域的重点研究方向之一。由于生物质含氧元素较多，在生物质热裂解中，裂解的燃气中含有较高的CO2，达到12%～30%。若使用燃气前，将二氧化碳捕获与分离，燃气可富集浓缩约1.12～1.3倍，则燃气可大幅度提高热值。
沸石咪唑酯骨架材料（ZIFs）是由金属离子（Zn2+和Co2+）与咪唑酯环（Im）形成一系列具有不同性质的多孔材料，具有很多优异的物化性质，相比于早起的MOFs多孔材料不同（如MOF-5遇水骨架结构会坍塌），ZIFs多孔材料具有极其稳定的化学和热物理性质性质，能耐水及有机溶剂。并且ZIFs具有较高的表面积和孔容，在CO2，CH4，H2等小分子气体储存方面具有优异性能，尤其对CO2气体分子具有较高的吸附选择性。因此，ZIFs多孔材料有利于CO2除去。
MOFs材料提高CO2气体吸附分离性能的方法主要有化学改性法，由于二氧化碳气体具有独特物化性能，有针对性对MOFs材料的金属节点位（增加不饱和金属位点、电荷数）、有机配体（氨功能化、氢键）以及改性骨架功能化从而提高CO2的吸附分离性能。因此，近些年来，一些学者通过掺杂金属改性法来增加材料的吸附性能。
