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 energydispersive
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
