A new photocatalyst-based metal-organic framework (MOFs) Cr-PTC was synthesized from chromium ion and sodium perylene-3,4,9,10-tetracarboxylate by the solvothermal method. This study aims to construct MOFs Cr-PTC and analyze their degradation photocatalytic activity against methylene blue under mercury lamp irradiation as the visible light source. XRD Spectrum exhibited MOFs Cr-PTC has intensity at a value of 2θ = 9.17°; 12.865°; 25.621°; and 27.85°. MOFs Cr-PTC has a narrow bandgap energy of 2.01 eV. MOFs Cr-PTC has good photocatalytic activity in methylene blue degradation under visible light irradiation at neutral pH with 87.22 mg/gram degradation capacity for 180 minutes. Species that play a dominant role in photocatalytic methylene blue degradation are hydroxyl radicals (•OH) and holes (h+ ) and are assisted by other species such as excited electrons (e- ) and superoxide radicals (•O2 - ). |
