The Exact Morphology of Metal Organic Framework MIL‐53(Fe) Influences its Photocatalytic Performance**

Abstract Controllable synthesis of Metal‐organic frameworks (MOFs) with well‐defined morphology, composition and size is great importance towards understanding their structure‐property relationship in various applications. Herein, the effect morphology photocatalysts on optical behavior photocatalytic efficiency was identified utilizing physical synthetic parameters for methylene blue removal. For this purpose, MIL‐53(Fe) fabricated as an efficient photocatalyst via solvothermal approach using chloride nitrate salts different secondary block unit (SBU) sources. Each powders obtained by two metal sources synthesized at three temperatures (120, 150, 180 °C). The MOFs were methodically investigated characterized terms structural, textural, morphological optical. empirical data confirmed that particles 120 °C iron exhibit highest This could be associated to high surface area UV light absorption comparison other samples. These results can considered future research maximize degradation organic dyes a serious pollutant wastewater.
