Fe2BiSbO7was synthesized by a solid-state reaction method for the first time. The structural and photocatalytic properties of Fe2BiSbO7have been characterized. The results showed that Fe2BiSbO7was crystallized with the pyrochlore-type structure, cubic crystal system, and space groupFd3m. The lattice parameter for Fe2BiSbO7was  Å. The photocatalytic degradation of methylene blue (MB) was realized under visible light irradiation with Fe2BiSbO7as catalyst. Fe2BiSbO7owned higher catalytic activity compared with Bi2InTaO7or pure TiO2or N-doped TiO2for photocatalytic degradation of MB. The photocatalytic degradation of MB with Fe2BiSbO7, Bi2InTaO7, or N-doped TiO2followed the first-order reaction kinetics, and the first-order rate constant was 0.01189, 0.00275, or 0.00333 min−1. After visible light irradiation for 230 min with Fe2BiSbO7, complete removal and mineralization of MB was observed. The reduction of the total organic carbon, the formation of inorganic products, and , and the evolution of CO2revealed the continuous mineralization of MB during the photocatalytic process. The photocatalytic degradation pathway of MB was obtained. Fe2BiSbO7/(visible light) photocatalysis system was found to be suitable for textile industry wastewater treatment.

In this work, anionic RR4 dye was used to sensitize TiO2/PVA and TiO2/PEG immobilized system in enhancing photocatalytic degradation of anionic methyl orange (MO) dye. 0.3g of TiO2 and polymer binder was coated onto a clean glass plate by using brush technique to develop optimum immobilize TiO2 system. A comparison study between immobilized TiO2/PVA (Im/TiO2/PVA) and immobilized TiO2/PEG (Im/TiO2/PEG) system with and without RR4 sensitizer were carried out under 55-W fluorescent lamp and visible light irradiation. The photocatalytic degradation of MO was significantly enhanced for both RR4 dye sensitized Im/TiO2/PVA and Im/TiO2/PEG with first order rate constant was ca. 0.080 min-1 and 0.071 min-1 respectively under 55-W fluorescent lamp. Same observation as well under visible light irradiation whereby enhanced of those RR4 sensitized immobilized photocatalysts were recorded as compared with immobilized photocatalysts without RR4 as sensitizer. The photocatalytic enhancement under Im/TiO2/PVA/RR4 and Im/TiO2/PEG/RR4 are due to the ability of RR4 dye to become electron (e-) donor for conduction band (CB) of TiO2, thus making TiO2 CB riches with electron, eventually this e is used to remove MO dye by producing hydroxyl radical.
