SINTESIS DAN KARAKTERISASI Zn-TEREFTALAT MOF SEBAGAI KATALIS PADA PEMBUATAN BIODIESEL DARI LIMBAH MINYAK GORENG

---

This study aims to synthesize and characterize Zn–Terephthalate MOF as a bifunctional heterogeneous catalyst for biodiesel production from waste cooking oil. The material was synthesized via a solvothermal method with variations in the precursor ratio of Zn(NO₃)₂·6H₂O to terephthalic acid (1:2, 1:1, and 2:1) to evaluate the effect of metal–ligand composition on structural properties and catalytic activity. Characterization using XRD, FTIR, TGA, PSA, and SEM-EDX confirmed the formation of crystalline Zn–Terephthalate MOF with effective Zn²⁺–BDC coordination, good thermal stability, uniform morphology, and particle size distribution favorable for increasing the active surface area. The synthesized catalysts were subsequently applied in the conversion of waste cooking oil to biodiesel, and the reaction conditions were optimized using Response Surface Methodology (RSM) based on Central Composite Design (CCD). The variation in precursor ratio significantly influenced the structural properties and catalytic performance, with the 1:1 ratio exhibiting the best performance, achieving a biodiesel conversion of 94.17% under optimum conditions of 3 g catalyst loading, 100 °C reaction temperature, and 150 min reaction time. These results demonstrate that tuning the metal–ligand ratio in MOF structures plays a crucial role in enhancing catalytic efficiency for biodiesel production from waste cooking oil.
