The grain-like BiOCl (60%)–Bi₂₄O₃₁Cl₁₀ (40%) intra-heterojunction nanophotocatalyst was fabricated by a facile one-pot combustion route using sorbitol fuel. It was characterized by the utilization of XRD, FESEM, PSD, BET–BJH and DRS, which proved its successful synthesis. The solar-light-driven photocatalytic activity of BiOCl (60%)–Bi₂₄O₃₁Cl₁₀ (40%) was appraised through the destruction of fluoroquinolone antibiotics (FQAs) such as ciprofloxacin, ofloxacin and levofloxacin as persistent and resisting emerging pollutants in an aqueous solution. Consequences obtained were implied to its prominent performance. To investigate the individual and interplay influences of the input operating parameters (catalyst loading, initial pollutant concentration, initial pH and reaction time), the modelling of the photocatalytic destruction of ofloxacin as the response was done by 2-level full factorial experimental design approach. A semi-empirical fourth-order regression model with R²= 0.9878 was expressed to relate between the response and independent variables. Results obtained of the mentioned approach demonstrated the high adequacy of the model. The influence of individual parameters and their interactions on the photocatalytic degradation efficiency of ofloxacin was possessed by the main effect graphs, contour and response surface plots. This study not only illustrates a hopeful application of the grain-like BiOCl–Bi₂₄O₃₁Cl₁₀ in the solar-light-driven photo-destruction of resistant pollutants such as FQAs but also shows the favourable direction to gain the high-performance.

采用山梨糖醇燃料通过一锅法燃烧法制备了晶粒状BiOCl（60％）– Bi ₂₄ O ₃₁ Cl ₁₀（40％）内异质结纳米光催化剂。它的特点是利用XRD，FESEM，PSD，BET-BJH和DRS，证明了其成功的合成。BiOCl（60％）– Bi ₂₄ O ₃₁ Cl ₁₀的太阳光驱动的光催化活性（40％）通过破坏氟喹诺酮类抗生素（FQA）（如环丙沙星，氧氟沙星和左氧氟沙星）作为持久性和抵抗水溶液中新出现的污染物而得到评估。获得的结果暗示了其出色的性能。为了研究输入操作参数（催化剂负载，初始污染物浓度，初始pH和反应时间）的个体和相互作用影响，通过2级全因子实验设计方法对氧氟沙星作为响应的光催化破坏进行了建模。具有R ^2的半经验四阶回归模型= 0.9878被表示为与响应和独立变量之间的关系。通过上述方法获得的结果证明了该模型的高度正确性。主要作用图，轮廓图和响应面图具有各个参数及其相互作用对氧氟沙星光催化降解效率的影响。这项研究不仅说明了粒状BiOCl–Bi ₂₄ O ₃₁ Cl ₁₀在太阳光驱动的诸如FQA等抗性污染物的光解中的有希望的应用，而且还显示了获得高性能的有利方向。
