dc.description.abstractA series of green synthesis methods were applied to synthesize [Cu3(BTC)2(H2O)3]n (CuBTC). The established method uses only water as the synthesis solvent and it is able to be carried out at room temperature. By applying the same synthesis system, a second compound, Cu2(OH)(BTC)(H2O)􀁹2H2O was successfully synthesized by altering the synthesis procedure. These compounds were subjected to the removal of methylene blue (MB) dye. CuBTC shows greater adsorption capability compared to Cu2(OH)(BTC)(H2O)􀁹2H2O as CuBTC exhibits higher BET surface area and pore volume. Two different approaches were used to further enhance the performance of the adsorbent which are the preparation of polyhydroxybutyrate-CuBTC (PHB-CuBTC) composite and altering the metal center of CuBTC by adding different amounts of iron into the metal center to produce bimetallic organic frameworks (BMOFs). All samples were subjected to N2 adsorption-desorption analysis, scanning electron microscope (SEM), and Fourier transform infrared spectroscopy (FTIR). Presence of PHB promotes the adsorption of MB, thus PHB-CuBTC composites (24.49 mg/g) shows greater adsorption capacity when compared to CuBTC (16.03 mg/g). The addition of polyvinylpyrrolidone (PVP) into PHB-CuBTC allows small amount of methyl orange (MO) adsorption and reduced the time required to achieve adsorption equilibrium for MB adsorption as compared to PHB-CuBTC. Subsequently, a series of Cu-Fe-BTC were successfully synthesized.en_US
