A synergistic combination of surface adsorption capabilities and photocatalytic efficiency is crucial for the removal of pollutants from water. Here, the efficacy of such a process is explored through the assembly of a heterostructured photocatalyst (Ag₃PO₄/TiO₂/SiO₂) by loading silver phosphate (Ag₃PO₄) onto titanium dioxide (TiO₂: P25)-coated silica (SiO₂) felt. This heterostructure demonstrated an enhanced tendency to absorb light due to its significantly low band-gap energy of 2.5 eV. As such, it exhibited enhanced photocatalytic performance to efficiently degrade an organic dye (methylene blue) under solar-light irradiation (e.g., 30% and 10% relative to pristine P25 and P25-coated SiO₂ felt, respectively). The maximum degradation efficiency for methylene blue was 99% with a first-order kinetic model (k = 0.39 min⁻¹). The calculated quantum yield of Ag₃PO₄/TiO₂/SiO₂ (3.26 × 10⁻³ molecules/photon) was significantly higher than that of other photocatalytic systems (e.g., ∼3260 times other reported hetrostructures, e.g., rGO/TiO_2, Ni-doped/TiO₂, and Cds/CoFe₂O₄) with good reusability in terms of the degradation efficiency (e.g., 99% for the first cycle and 81% for the fourth). Ag₃PO₄/TiO₂/SiO₂ is therefore recommended for the efficient treatment of organic pollutants in wastewater systems.

表面吸附能力和光催化效率的协同结合对于从水中去除污染物至关重要。在此，通过将磷酸银（Ag ₃ PO ₄）负载到涂有二氧化钛（TiO ₂：P25）的异质结构光催化剂（Ag ₃ PO ₄ / TiO ₂ / SiO ₂）的组装中，探索了这种方法的功效。二氧化硅（SiO ₂）感到。这种异质结构显示出增强的吸收光的趋势，这是由于其显着较低的2.5 eV带隙能量。这样，它表现出增强的光催化性能，以在太阳光照射下有效降解有机染料（亚甲基蓝）（例如，相对于原始的P25和P25涂层的SiO ₂毡分别为30％和10％）。在一级动力学模型（k = 0.39 min ^-1）下，亚甲基蓝的最大降解效率为99％。Ag ₃ PO ₄ / TiO ₂ / SiO ₂（3.26×10 ^-3分子/光子）显着高于其他光催化体系（例如，约3260倍的其他报道的异质结构，例如rGO / TiO _2， Ni掺杂/ TiO ₂和Cds / CoFe ₂ O ₄），具有良好的可重用性效率（例如，第一个循环为99％，第四个循环为81％）。因此，推荐使用Ag ₃ PO ₄ / TiO ₂ / SiO ₂对废水系统中的有机污染物进行有效处理。
