Mn, Zr co-doped Ag₂O nanoparticles (NPs) were blended through a wet chemical strategy, and the physicochemical properties of doped and co-doped silver oxide nanoparticles were characterized using X-ray diffraction, UV-DRS visible spectroscopy, Fourier transform infrared spectroscopy, scanning electron microscopy with energy dispersive X-ray spectroscopy, high-resolution transmission electron microscopy, Brunauer–Emmett–Teller (BET) and electrochemical impedance spectroscopy (EIS) and photoluminescence techniques. XRD reveals that the crystal structure of Mn, Zr co-doped Ag₂O NPs has a face-centered cubic phase (FCC). Photoluminescent spectra analysis further demonstrates that the Mn, Zr co-doped Ag₂O extraordinarily improves the charge generation and suppresses the charge recombination of photogenerated electron–hole pairs, which would be advantageous to improving the photocatalytic properties. The photocatalytic properties of Mn, Zr co-doped Ag₂O NPs were assessed by the degradation of rose bengal dye under visible light illumination. The results revealed that Mn, Zr co-doped Ag₂O (Mn, Zr–Ag₂O) showed greater photocatalytic activity compared with different photocatalysts. In addition, Mn, Zr co-doped Ag₂O was seen as a reusable photocatalyst.

掺有Mn和Zr的Ag2O纳米粒子的设计及其可见光辐照对玫瑰孟加拉染料降解的增强光催化活性

通过湿化学策略共混Mn，Zr共掺杂的Ag ₂ O纳米颗粒（NPs），并通过X射线衍射，UV-DRS可见光谱，傅里叶变换表征了掺杂和共掺杂的氧化银纳米颗粒的理化性质。红外光谱，具有能量色散X射线光谱的扫描电子显微镜，高分辨率透射电子显微镜，Brunauer-Emmett-Teller（BET）以及电化学阻抗谱（EIS）和光致发光技术。X射线衍射表明，Mn，Zr共掺杂的Ag ₂ O NPs的晶体结构具有面心立方相（FCC）。光致发光光谱分析进一步表明，Mn，Zr共掺杂Ag ₂O特别地改善了电荷产生并抑制了光生电子-空穴对的电荷复合，这将有利于改善光催化性能。Mn，Zr共掺杂的Ag ₂ O NPs的光催化性能通过在可见光照射下玫瑰花型孟加拉染料的降解来评估。结果表明，与不同的光催化剂相比，Mn，Zr共掺杂的Ag ₂ O（Mn，Zr–Ag ₂ O）具有更高的光催化活性。另外，Mn，Zr共掺杂的Ag ₂ O被视为可重复使用的光催化剂。
