Abstract

Metal-containing mesoporous starches have been synthesized using a simple and efficient microwave-assisted methodology followed by metal impregnation in the porous gel network. Final materials exhibited surface areas >60 m² g, being essentially mesoporous with pore sizes in the 10-15 nm range with some developed inter-particular mesoporosity. These materials characterized by several techniques including XRD, SEM, TG/DTA and DRIFTs may find promising catalytic applications due to the presence of (hydr)oxides in their composition.

摘要

含金属的介孔淀粉已通过一种简单高效的微波辅助方法合成，随后在多孔凝胶网络中进行金属浸渍。最终材料的表面积大于60 m²/g，基本上是介孔的，孔径在10-15 nm范围内，且具有一些发达的颗粒间介孔。这些通过包括XRD、SEM、TG/DTA和DRIFTs在内的多种技术表征的材料，由于其组成中存在（氢）氧化物，可能会有很有前景的催化应用。
