采用水热法制备了多孔NiCo 2 O 4纳米片。采用XRD、FTIR、N2吸附-脱附等温线和TEM对产物的形貌和晶体结构进行了表征。该复合材料对刚果红（CR）具有良好的吸附性能，最大吸附量可达961.5 mg/g。在CR溶液中，无需调节pH即可达到最佳吸附性能，吸附符合朗缪尔等温吸附模型，吸附动力学模型更符合准二级模型。吸附机理研究表明，复合材料中的金属离子与氯丁橡胶中的-SO 3-形成离子键，而不是静电引力。NiCo 2 O 4纳米片可以作为高性能刚果红吸附剂的替代品。
In this work, porous NiCo2O4nanosheets have been fabricated by a facile hydrothermal method. The morphology as well as crystalline structure of products was tested by XRD, FTIR, N2adsorption-desorption isotherms and TEM. The composite exhibited excellent adsorptive removal capacity toward Congo red (CR), and the maximum adsorption capacity was up to 961.5 mg/g. The best adsorption performance was achieved in the CR solution without adjusting of pH. Adsorption accords with Langmuir isothermal adsorption model and the adsorption kinetic model is more in line with the pseudo-second order model. According to the adsorption mechanism investigation, adsorption was not caused by the electrostatic attractions but may be the formation of ionic bonding between metal ion in composite and -SO3-in CR. The NiCo2O4nanosheets can be a good alternative for the high-performance Congo red adsorbent.
