將Anatase (A)-TiO2旋塗在水熱法生成的Rutile (R)-TiO2 奈米柱陣列薄膜上，形成junction (A/R-TiO2)，接著透過化學還原法在A-/R-TiO2上複合Ag 奈米顆粒，形成用於光催化應用的多相複合材料 (Ag/A/R-TiO2)。XRD和SEM分析分別揭示了它們的晶相和形貌，TEM結果確定了不同相間的耦合，XPS展示了所有組成元素。
Ag/A/R-TiO2 (0.05M 10%，after FGA) 展現出優異的Rhodamine B降解性能，在80分鐘內達到100%降解 (k = 2.63×10-2 min-1)，經過五次連續循環測試後，樣品的降解能力沒有顯著下降，證實了其耐久性。犧牲劑測試驗證光催化降解反應中主要是h+和•O2⁻自由基起主導作用。
Ag/A/R-TiO2 (0.05M 10%，after FGA) 在可見光照射下對噬菌體MS2的光催化消毒效果也最為顯著，在100分鐘內達到約90%的消毒效率。雖然Ag/A/R-TiO2在可見光照射下的消毒效率不如紫外光（在40分鐘內幾乎達到100%滅菌），但該材料可應用於有人環境，對人體無威脅，因此具有無限潛力。
結合UV-Vis, UPS和SKPM的結果構建了該複合材料的能帶圖，其中在可見光誘導的局域表面電漿共振（LSPR）效應下，Ag表面產生的熱電子轉移到A-TiO2的導帶（EC），並沿著能帶流向R-TiO2，而h+ 則留在Ag中，實現了理想的電荷分離（染料敏化太陽能電池機制）。此外，A-TiO2和R- TiO2的缺陷和形貌也增加了對可見光的吸收，這些特性協同作用，導致了該材料的優異性能。

Anatase (A)-TiO2 was spin-coated on hydrothermally grown rutile (R)-TiO2 nanorod array films to form a junction (A/R-TiO2), and Ag nanoparticles were then chemically reduced and decorated on A/R-TiO2 to form a multiphase composite of Ag/A/R-TiO2 for application to photocatalysis. XRD and SEM analyses revealed their crystalline phases and morphologies, respectively. TEM results determined the coupling of the constituent components. XPS revealed all constituent elements.
Ag/A/R-TiO2 (0.05M 10%, after FGA) exhibited outstanding Rhodamine B degradation performance, achieving 100% degradation in 80 min (k = 2.63×10-2 min-1). The sample’s durability was revealed by no noticeable deterioration in degradation capability after five consecutive cycles. Radicals h+ and •O2⁻ were determined to be predominant in the photocatalytic degradation reaction.
Ag/A/R-TiO2 (0.05M 10%, after FGA) also exhibited the most promising photocatalytic disinfection of bacteriophage MS2 (approximately 90% disinfection efficiency within 100 min) under visible light illumination among all samples. Although Ag/A/R-TiO2 under visible light illumination did not exhibit the disinfection as effectively as UV-light (nearly 100% sterilization within 40 min), the material can be applied to an environment of personnel, posing no threat to human health.
UV-Vis, UPS, and SKPM were employed to construct an energy band diagram of the composite, in which hot electrons generated on the surface of Ag under visible-light induced localized surface plasmon resonance (LSPR) effect transfer to the EC of A-TiO2 and then flow along the band to R-TiO2, while the holes remain in Ag, achieving desirable charge separation (dye-sensitized solar cell mechanism). Furthermore, defects and morphologies of A- and R-TiO2 also extend optical absorption to visible light. These characteristics synergistically lead to the outstanding performance
