The ZnAl Layer Double Hydroxides-based material was modified to enhance its performance in removing Tetracycline in waters. It was calcined at 500 °C to form ZnAl Layer Double Oxides. The restacking-delaminating method is used to intercalate the Clitoria ternatea flower extract into the two catalysts interlayer, resulting in two modified catalysts. These modified catalysts exhibit FT-IR spectra that show a combination of the catalyst and Clitoria ternatea flower extract. ZnAl Layer Double Oxides, which lost the water molecules and interlayer anions, only demonstrated metal oxide vibration peaks in the FT-IR spectra. The XRD patterns of ZnAl Layer Double Hydroxides and ZnAl Layer Double Oxide, respectively, resemble the XRD pattern of standard materials. The reconstructed ZnAl Layer Double Oxide forms ZnAl Layer Double Oxide-Clitoria ternatea flower extract with a layered structure (the diffractogram peak at 2θ 10–11° reappears). ZnAl Layer Double Hydroxides-Clitoria ternatea flower extract could efficiently capture light in the ultraviolet (UV) and visible regions, as indicated by its energy bandgap value of 2.39. The synthesized material was employed in a batch system as a photocatalyst for the Tetracycline degradation. With a 92.25 % Tetracycline removal percentage, ZnAl Layer Double Oxide exhibited the most excellent performance in its capacity as a hybrid catalyst-adsorbent material. After the fifth regeneration, ZnAl Layer Double Hydroxides-Clitoria ternatea flower extract exhibited catalytic performance to degrade Tetracycline entirely in 90 min.

对 ZnAl 层双氢氧化物基材料进行了改性，以增强其去除水中四环素的性能。在500℃下煅烧形成ZnAl层双氧化物。采用重新堆叠-分层方法将蝶豆花提取物嵌入到两种催化剂夹层中，得到两种改性催化剂。这些改性催化剂的 FT-IR 光谱显示了催化剂和蝶豆花提取物的组合。ZnAl层状双氧化物失去了水分子和层间阴离子，在FT-IR光谱中仅表现出金属氧化物振动峰。ZnAl 层双氢氧化物和 ZnAl 层双氧化物的 XRD 图案分别类似于标准材料的 XRD 图案。重建的 ZnAl 层双氧化物形成具有层状结构的ZnAl 层双氧化物 -蝶豆花提取物（在 2θ 10–11° 处的衍射图峰再次出现）。ZnAl 层双氢氧化物 -蝶豆花提取物可以有效捕获紫外线 (UV) 和可见光区域的光，其能带隙值为 2.39。合成材料在间歇系统中用作四环素降解的光催化剂。ZnAl 层双氧化物的四环素去除率为 92.25%，作为混合催化剂-吸附材料表现出最优异的性能。第五次再生后，ZnAl层双氢氧化物-蝶豆花提取物表现出催化性能，在90分钟内完全降解四环素。
