Ni-BTC (BTC = 1,3,5-benzene tricarboxylate) metal organic framework (MOF) was synthesized using different solvent conditions. Solvent mixtures of water/N,N-dimethylformamide (DMF), water/ethanol, and water/ethanol/DMF were used for the reactions with or without a variety of bases at 160 C for 48 hours. Even with same green crystals, prepared MOFs show all different BET surface areas and different XRD patterns. The highest BET surface area of the crystals was 850 m 2 /g obtained from water/DMF solvent with NH 4 OH as a base. The measured surface areas of the crystals follows the order of Ni-BTC (water/DMF-NH4OH) > Ni-BTC (water/DMF-TMA) > Ni-BTC (water/DMF) > Ni-BTC (water/DMF-Pyridine) > Ni-BTC (water/ethanol) > Ni-BTC (water/DMF-aniline) > Ni-BTC (water/DMF-NaOH) .
