Abstract
This study reported the fabrication of TiO2-decorated Fe2O3QDs/g-C3N4 ternary Z-scheme photocatalyst via low-temperature calcination followed by a nonaqueous route with tunable particle size and strong interfacial contact. The subsequent Fe2O3QDs/g-C3N4 and TiO2/Fe2O3QDs/g-C3N4 were investigated in terms of structure, morphology, optical properties, and surface chemical composition analysis via transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), energy dispersive x-ray spectroscopy (EDX), UV–visible spectroscopy, ESR and photoluminescence spectroscopy (PL). The crystalline parameters of the samples were investigated by X-ray diffraction (XRD) The Williamson-Hall method and geometrical phase analysis of HRTEM micrographs were employed to investigate lattice defects. Under visible light, the photocatalytic capabilities of as-fabricated TiO2/Fe2O3QDs/g-C3N4 were examined by degrading Rhodamine B (RhB), and an enhancement in photocatalytic efficacy was found. TiO2 works as a primary photosensitizer, providing extra photoinduced electrons influenced by oxygen vacancies, while Fe2O3 acts as a "bridge" for electron transport from the TiO2 moiety to the g-C3N4 thereby establishing an indirect charge transport pathway based on the Z-scheme. Radical scavenging tests were conducted to further explore the cause of increased activity and degradation mechanisms. Designing materials with oxygen vacancies and optimized structures can lead to improved solar energy conversion capabilities, particularly regarding contaminant removal. The proposed technique might be a viable option for the removal of rhodamine b compounds and for remedying freshwater reservoirs.
Graphical Abstract
TiO2 /Fe2O3QDs/g-C3N4Ternary Z-Scheme Photocatalysts! A facile strategy is exploited to modulate the crystallinity and surface properties of TiO2. TiO2 is incorporated into Fe2O3QDs/g-C3N4 through solvothermal treatment, which results in the formation of surface flaws and lattice-oxygen activated regions as well as the transformation of the Fe2O3QDs/g-C3N4 heterojunction into an indirect z-scheme system by rational modulation of the band alignment of two systems. The electron–hole pair is efficiently separated, conserving the electron reduction capability and the electron oxidation capability of the hole. The adapted structure and mesocrystalline nature resulted in a 7.3-fold improvement in the photocatalytic performance of TFCN over pure g-C3N4.
