SINTESIS DAN KARAKTERISASI FOTOKATALIS ALUMINIUM TEREFTALAT/GRAPHITE OXIDE (AlBDC/GO) KOMPOSIT SEBAGAI PENDEGRADASI PEWARNA METIL ORANYE DALAM PELARUT AIR

Abstract

In this final project nanocomposite between metal-organic frameworks (MOF) and graphite oxide (GO), specifically, AlBDC/GO was successfully synthesized using the solvothermal method with Aluminum Nitrate (Al (NO3)3.9H2O) as the source of Al ions and benzene-1,4-dicarboxylic acid (BDC) as the source of organic ligan. After a series of procedures namely recovering and activating AlBDC/GO, the sample was characterized by FTIR, SEM, and XRD. The as- prepared AlBDC/GO nanocomposite has two types depending on different GO weight concentrations, I.e., AlBDC/GO 2% wt. and AlBDC/GO 5% wt. These materials together with AlBDC were used as photocatalysts for the degradation of methylene orange (MO). Both AlBDC and AlBDC/GO nanocomposites exhibited moderate photocatalytic activity both in UV-B light and in sunlight irradiation. in UV light irradiation, AlBDC gave the best photocatalytic performance with an 11,96% of degradation rate, while during sunlight irradiation, the AlBDC/GO 5% wt. gave the best result in the degradation rate of MO by 7.84%. these data were obtained after two hours of irradiation.
