Synthesis and photocatalytic performance of Bi ₂₄ O ₃₁ Cl ₁₀ /V ₂ O ₅ composites for rhodamine B degradation under visible-light irradiation
Abstract
A new composite system, (1Àx) Bi 24 O 31 Cl 10 /xV 2 O 5 , with 0 r x r 1, was synthesized by simple solidstate reactions followed by thermal treatment. X-ray diffraction analysis and scanning electron microscopy were used to characterize the crystal structures and morphologies of each constituent.
Diffuse reflectance spectroscopy showed that the optical band gaps of all samples ranged between 2.26 eV (V 2 O 5 ) and 2.9 eV (Bi 24 O 31 Cl 10 ). The intermediate biphasic system with x = 0.5 exhibited the best photocatalytic performance, with a pseudo-first-order rate constant (K app ) of approximately 0.073 min À1 and 98% degradation of rhodamine B (RhB) in 60 min under visible light irradiation. Experimental results demonstrated that the same composite with x = 0.5 also exhibited excellent performance in the photodegradation of other dyes such as methylene blue (MB), methyl orange (MO), and orange G (OG).
Studies on the traps suggested that the most important active species were photogenerated holes (h + ) and superoxide radicals. The x = 0.5 photocatalyst also exhibited excellent stability and reusability in tests over five successive cycles, indicating its potential in the field of sustainable water purification technologies.
