“…In this eld, a novel 3D ower-like Bi 3 O 4 Cl/BiOCl heterostructure was prepared by a coprecipitation method for degradation of antibiotic drug. 156 The composite exhibited a high photocatalytic activity in visible light range for the efficient charge-separation properties, which degraded 87% levooxacin in 180 min. In addition, mesoporous-mixed-phase bismuth oxychlorides was fabricated by using one-pot sorbitol-nitrate solution autocombustion method, 157 and the intra-heterojunction containing 59% BiOCl and 41% Bi 24 O 31 Cl 10 displayed a high activity for degradation of antibiotic ooxacin, due to the enhanced light absorption and surface reactions by a high porosity.…”

“…202 The photocatalysts exhibited high visible light absorption and separation rate of charge carriers for Orange II degradation. 3D flower-like Bi 3 O 4 Cl/ BiOCl composites consisting of nanoplates can also be prepared, 203 which possessed a large special surface area, high visible light absorption, stability, as well as ultralong lifetimes of charge carriers for accelerating the levofloxacin degradation. Notably, the fabrication of above composites strongly depended on the concentration of NaOH and synthetic strategies.…”

The construction and regulation of heterogeneous interfaces are beneficial to improve solar light harvesting and photocharge separation of hybrid BiOCl-based photocatalysts, which are attributed to the synergistic effects that originate from the integrated interaction between disparate components. With the rapid development of synthetic technologies, hybrid BiOCl-based micro-/nanostructures with diversified components, morphologies, and sizes have been well prepared. Moreover, hybrid BiOCl-based photocatalysts have presented a promising potential for various photocatalytic applications, such as organic pollutant degradation, hydrogen production, NO removal, CO2 reduction, heavy metal ion detection, disinfection, nitrogen fixation, and alcohol oxidation. Previously, several review articles have mainly summarized the advances made in synthetic methods, morphological control, modification strategies, and applications of the bare BiOCl micro-/nanostructures. However, a comprehensive overview based on the type of species and the corresponding correlations between microstructures, performances, as well as photocatalytic mechanisms has been less reported for hybrid BiOCl-based photocatalysts so far. Therefore, a comprehensive understanding of the basic theory and research progress of hybrid BiOCl-based photocatalysts is imperative. This review aims to provide an overview of the important advances made in eight types of hybrid BiOCl-based photocatalysts, including metal/BiOCl, metal oxide/BiOCl, metal sulfide/BiOCl, BiOX (X = Cl, Br, I)/BiOCl, AgX (X = Cl, Br, I)/BiOCl, organics/BiOCl, carbon/BiOCl, and other BiOCl-based multicomponents. In each classification, the synthetic methods, modification strategies, relationships between interfacial microstructures, and enhanced performances are discussed based on some typical examples. Additionally, some scientific issues and potential directions are also given. Hopefully, this review paper will provide a useful reference for researchers currently focusing on exploring new BiOCl-based photocatalysts.

“…The degradation efficiency for initial LFX concentration of 25, 50 and 100 mg/L is found as 88.7%, 75.5% and 71.2%, respectively. Degradation efficiency is decreased at higher concentrations of pollutant, which might be due to more adsorption of pollutant molecules which resulted in unavailability of catalytic surface for developing the hydroxyl radicals [52,53]. 0.5CuT is also employed for checking the effect of photocatalyst amount on the degradation performance of LFX under visible light.…”

The degradation performance of Cu-TiO 2 nanomaterials towards levofloxacin (LFX) antibiotic was investigated under an environmentally benign visible LED light source. Cu-TiO 2 nanomaterials were prepared using the reverse micelle sol-gel method with different copper content ranging from 0.25 to 1.0 wt% concerning titania. Characterization of Cu-TiO 2 samples was performed by XRD, TEM, UV-Vis, BET, ICP-MS, FTIR and XPS techniques. 0.5 wt% Cu-TiO 2 showed crystallite size below 6 nm, surface area (69.85 m 2 /g) and significant visible light absorption capacity. Both Cu 1+ and Cu 2+ are formed in lower Cu-doped TiO 2 samples, whereas only Cu 2+ is present in higher Cu-doped TiO 2 samples as evident in XPS analysis. 0.5 wt% Cu-TiO 2 has shown the optimum photocatalytic degradation of 75.5% under 6 h. of a visible light source. FTIR analysis of LFX adsorbed Cu-TiO 2 materials indicated the pollutant-catalyst interaction, where the declining trend was observed in photocatalytic degradation efficiency for higher Cu-doped TiO 2 samples due to copper-LFX complex formation.Copper-LFX complexes are formed due to the presence of Cu 2+ in higher Cu-doped TiO 2 nanomaterials, which might have hindered the photocatalytic activity under visible light. Effects of initial pollutant concentration, catalyst loading and visible light intensity on the degradation of LFX are studied. Photocatalytic degradation pathways of LFX using best performing Cu-TiO 2 material were also proposed based on the LC-MS analysis.
