“…It is well-known that the photoluminescence spectrum (PL) is an effective tool to estimate the recombination probability of photo-generated charge carriers [ 42 ]. As the emission signal is derived from the recombination of photo-induced e − , h + pairs, the weaker the emission signal is, the higher the separation efficiency of charge carriers.…”

“…Because a smaller semicircle the electrochemical impedance spectroscopy (EIS) Nyquist plot means an overall small charge transfer resistance and a faster interfacial charge transfer, the electron mobility greatly accelerated and the recombination rate of photo-generated electrons and holes effectively inhibited when the MnFe2O4/BGA composite is applied as a visible light ph tocatalyst. It is well-known that the photoluminescence spectrum (PL) is an effective tool to estimate the recombination probability of photo-generated charge carriers [42]. As the emission signal is derived from the recombination of photo-induced e − , h + pairs, the weaker the emission signal is, the higher the separation efficiency of charge carriers.…”

“…In tetracycline degradation by SrTiO 3 /MnFe 2 O 4 microwave-ultraviolet system, trapping experiment shows that • OH takes an important and major role. ESR technique is also supported the above ROS, as the high intensity 1:2:2:1 characteristics signal of DMPO-• OH than 1:1:1:1 signal of DMPO-• O 2 −[28].…”

“…The enhancement of degradation efficiency is due to the reduction of electron hole recombination rate by the introduction of Gd. The presence of partially filled 4f orbital of Gd facilitates to trap conduction band electron and leads to the formation of superoxide anion radical according to the following way [26]: [28]. Mn-and Ce-codoped BaTiO 3 [29] show photocatalytic activity for the degradation of congo red and titan yellow dye solution as shown in Figure 2.…”

“…Among the pharmaceutical compounds, tetracycline (TC) is also one of the most important antibiotics. Tetracycline forms antibiotic-resistant genes and ecotoxicity in aquatic systems, and widely exists in soil, groundwater, surface water, and even drinking water [ 76 ]. It is considered a potential hazard to human health and aquatic ecosystems.…”
