Abstract

Composites synthesized from iron(III) citrate and carbon spheres, and activated with potassium compounds were prepared and then characterized using XRD, SEM, and low-temperature nitrogen adsorption methods. The adsorption properties of the composites toward carbon dioxide were assessed using CO uptake measurement, as well as by measuring their selectivity toward carbon dioxide, given their further application as photocatalysts for the reduction of this gas. The effect of changing preparation conditions on the structural and adsorption properties of the material was assessed. The potential strength of such material is a synergistic effect between the high adsorption capacity related to the microporosity of carbon spheres combined with the catalytic properties of iron particles.

摘要

制备了由柠檬酸铁（III）和碳球合成并用钾化合物活化的复合材料，然后使用X射线衍射（XRD）、扫描电子显微镜（SEM）和低温氮吸附法对其进行表征。通过测量一氧化碳（CO）的吸收量以及测量它们对二氧化碳的选择性，评估了复合材料对二氧化碳的吸附性能，因为它们进一步用作还原该气体的光催化剂。评估了改变制备条件对材料结构和吸附性能的影响。这种材料的潜在优势是与碳球微孔性相关的高吸附容量与铁颗粒的催化性能之间的协同效应。
