Photocatalysis is the most promising green approach to solve antibiotic pollution in water, but actual treatment effect limited by photocatalytic activity. Herein, Bi and BiOCl were loaded onto surface of Ce-MOF (metal–organic framework) using an electrostatic adsorption method, a special ternary heterojunction Ce/Bi/BiOCl was successfully prepared as photocatalyst for degradation tetracycline (TC). FTIR demonstrated that obtained contains functional groups such -COOH belonging characteristic crystal planes BiOCl, indicating successful construction photocatalyst. The results UV–vis absorption spectra confirm band gap reduced from 3.35 eV 2.7 eV, resulting enhanced light capability visible region. constructed Ce-MOF, Bi, could achieve narrow reasonable structure, thereby enhancing separation photogenerated charges. Consequently, performance significantly compared BiOCl. Therefore, can rate 97.7% within 20 min, which much better than (14.8%) (67.9%). This work MOF-based photocatalysts revealed relationship between heterojunctions provides inspiration constructing other heterogeneous catalysts use field photocatalysis.

The rapid photocarrier recombination limits the photocatalytic activity of iron titanate (FeTiO3) to be further improved. Developing novel approaches inhibit rate FeTiO3 photocatalysts is crucial for efficiently degrading pollutants in wastewater. Rare earth ions, with unique electron dispositions and large ion radii, could effectively recombination. Herein, lanthanum (La)-doped were designed successfully synthesized. performance 12 mol % La/FeTiO3 photocatalyst was superior tetracycline hydrochloride (TCH), methylene blue (MB), brilliant (BB). These degradation constants (k) 0.12358, 0.01357, 0.03064 L mg–1 min–1, respectively, which 12.83, 1.61, 7.78 times that pure FeTiO3. photoelectronic tests density functional theory (DFT) calculations revealed La 4f orbital forms an impurity energy level conduction band This narrows bandgap acts as acceptor, capturing photoexcited electrons inhibiting electron–hole pairs work enhances potential photocatalysis field provides important insights into efficient organic

China is a significant global producer and consumer of pesticides antibiotics, with their excessive use leading to substantial water pollution that poses challenges for subsequent treatment. Photocatalytic degradation, leveraging renewable solar energy, presents an effective approach decomposing organic pollutants reducing residual contaminant levels in bodies. This represents one way addressing environmental challenges. paper classifies representative photocatalytic materials by structural design degradation principles including MOFs (Metal–Organic Frameworks), metal- nonmetal-doped, mesoporous material-loaded, carbon quantum dot-modified, floatation-based, heterojunction photocatalysts. We also discuss research on pathways reaction mechanisms antibiotics. Of particular importance are several key factors influencing efficiency, which summarized within this work. These include the separation charge transfer rate catalyst surface carriers, wide-spectrum response capabilities photocatalysts, as well persulfate activation efficiency. Furthermore, emphasis placed role played intrinsic driving forces such built-in electric fields catalytic systems. Moreover, introduces promising composite-structure technologies from both perspectives (e.g., Aerogel-based composites) composite-method molecularly imprinted synthesis method). latest development status, along future prospects, presenting valuable insights pollutant targets. work aims facilitate efficient materials, while providing theoretical references governance technologies.

Abstract In this study, single‐phase g‐C 3 N 4 and FeTiO catalysts were synthesized by thermal polymerization hydrothermal methods, @g‐C binary composites successfully constructed method. The crystal structure, morphology, photoelectric properties of the samples characterized in all aspects characterization methods such as XRD, FI‐IR, SEM, XPS, BET, UV–vis, PL, effects different doping ratios, catalyst injection, initial concentration pollutants, pH, light source on degradation performance bisphenol A (BPA) investigated. It was shown that spherical chalcogenide particles loaded lamellar surface to form a composite with specific area 18.403 m 2 /g pore size 14.636 nm.
