英文摘要In this study, Mn-doped ZnIn2S4 (ZIS) was synthesized via a low-temperature hydrothermal method using Mn (CH3COO)2 and various inorganic Mn sources as doping agents, and the effects of organic and inorganic Mn doping sources were then compared. The results revealed that Mn(CH3COO)2 doping significantly enhanced both the specific surface area and photocatalytic degradation performance of ZIS compared to doping with inorganic Mn sources. Furthermore, organic Mn doping also notably improved the photocatalytic antibacterial performance of ZIS. Under visible light, the ZIS/Mn(CH3COO)2 = 2:1 demonstrated an increase in antibacterial efficiency of 8.11 %, 14.04 %, and 28.16 % against Pseudomonas aeruginosa, Escherichia coli, and Staphylococcus aureus, respectively. Steady-state and time-resolved photoluminescence results showed that Mn doping reduced the recombination rate of photogenerated carriers and extended their lifetime. Additionally, Electron Paramagnetic Resonance results indicated that Mn doping enhanced the concentrations of center dot O2-and center dot OH radicals in ZIS, providing direct evidence for the improved photocatalytic performance. Density Functional Theory calculations demonstrated that Mn doping lowered the work function of ZIS and that the formation of S-Mn covalent bonds promoted the migration of photogenerated carriers. After Mn doping, the D-band center shifted closer to the Fermi level, and the adsorption energy of O2 decreased, further facilitating the reaction between photogenerated electrons and O2. These factors collectively contributed to the enhanced photocatalytic degradation and antibacterial performance of Mn-doped ZIS. This study offers an in-depth analysis of the mechanism behind the improved photocatalytic performance of Mn-doped ZIS, and provides valuable insights into the selection of doping sources for future research.
