摘要

以3种形貌精准可控的铁基金属有机框架(MOFs)材料为牺牲模板,通过一步煅烧法成功制备了棒状、立方体状、球状3种不同形貌的磁性纳米多孔碳(MNPCs)材料。研究了不同形貌MOFs前驱体对MNPCs材料形貌的影响。采用透射电镜、水合粒径、红外光谱对材料进行表征,并考察不同形貌MNPCs的弛豫性能。结果表明,不同形貌的MOFs前驱体会影响MNPCs的形貌,且MNPCs的弛豫性能与形貌有着密切联系。MNPCs横向弛豫率较煅烧前的MOFs前驱体有了显著提高,其中,球状的MNPCs弛豫性能最佳,其横向弛豫率为34.205L/(mM·s)。

Abstract

Three kinds of magnetic nanoporous carbons (MNPCs) materials with controllable morphologies (rod,cubic,spherical) were successfully prepared by one-step calcination method using three kinds of iron-based metal organic frameworks (MOFs) with controllable shapes.The effects of different morphologies of MOFs precursors on the morphologies of MNPCs were investigated.The materials were characterized by transmission electron microscopy,hydrated particle size and infrared spectrum.The relaxation properties of MNPCs with different morphologies were investigated.The results showed that the MOFs precursors with different morphologies can affect the morphologies of MNPCs,and the relaxation properties of MNPCs were closely related to the morphologies.The transverse relaxation rates of MNPCs were significantly improved compared with the MOFs precursors.Among them,the spherical MNPCs had the best relaxation performance,with a transverse relaxation rate of 34.205L/(mM·s).
