Morphological and Elemental Characterization of a Mn-Based Metal-Organic Framework Synthesized from Sodium tartrate and Manganese Chloride

Metal-organic frameworks (MOFs) are an important class of porous materials that attract significant attention due to their unique structural properties and wide range of applications in catalysis, adsorption, and electrochemical systems. In this work, the morphology and elemental composition of a manganese-based metal-organic framework synthesized from Sodium tartrate and manganese chloride were investigated using scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS). SEM analysis revealed the formation of heterogeneous structures consisting of porous nanosized particles, crystalline domains, and larger agglomerates. The observed morphology suggests the presence of a high surface area and complex surface architecture. EDS analysis confirmed the presence of carbon, oxygen, sodium, potassium, chlorine, and manganese in the material. Quantitative elemental analysis demonstrated that carbon (37.80 wt.%) and oxygen (36.94 wt.%) are the dominant constituents, while manganese (9.51 wt.%) acts as the principal metallic component. Elemental mapping showed a relatively homogeneous distribution of manganese throughout the framework structure. The obtained results confirm the successful formation of a manganese-containing metal-organic framework with potential applications in catalytic and electrochemical systems.
