MOF-Derived In2O3 Microrod-Decorated MgIn2S4 Nanosheets: Z-Scheme Heterojunction for Efficient Photocatalytic Degradation of Tetracycline

“…The charge separation and migration behavior of the samples were revealed by electrochemical impedance spectroscopy (EIS) and a transient photocurrent response. The migration resistance of the photogenerated carriers is lower and the separation of the photogenerated carriers is more advantageous as the Nyquist radius decreases . As shown in Figure c, MIS-In 2 O 3 -(10:1) exhibits the smallest semicircle, indicating that the constructed Z-scheme heterojunctions can effectively reduce the charge transfer resistance and allow for the rapid transport of photoinduced charges, thus facilitating charge carrier separation.…”

“…The migration resistance of the photogenerated carriers is lower and the separation of the photogenerated carriers is more advantageous as the Nyquist radius decreases. 55 As shown in Figure 6c, MIS-In 2 O 3 -(10:1) exhibits the smallest semicircle, indicating that the constructed Z-scheme heterojunctions can effectively reduce the charge transfer resistance and allow for the rapid transport of photoinduced charges, thus facilitating charge carrier separation. Pure MIS and In 2 O 3 show comparatively low photocurrent intensities (Figure 6d) because of the rapid compounding of their photogenerated carriers during migration, resulting in a low photogenerated electron availability.…”

Direct Z-scheme heterojunction impregnated MoS2–NiO–CuO nanohybrid for efficient photocatalyst and dye-sensitized solar cell

“…Molybdenum Disulfide (MoS 2 ) has been used as a promising and prospective material due to its novel structure as well as unique electrical and optical characteristics. Especially, it has also been used as a platinum free counter electrode (CE) in DSSC and as a catalyst for photocatalytic activity 7 – 9 . Recent research has focused on the combination of MoS 2 with inorganic compounds such as metal sulfides, metal oxides, nitrides, and carbides to increase photocatalytic activity and DSSC solar cell performance via the use of simple production procedures.…”

Effects of iron oxide contents on photocatalytic performance of nanocomposites based on g-C3N4

“…Moreover, the nanocomposites exhibited a higher photocurrent density than that of the pristine g-C 3 N 4 , mainly due to their lower charge recombination rate.Semiconductor photocatalysts have been the subject of significant attention as a simple time and energy-efficient technology to convert organic pollutants into eco-friendly mineralized byproducts.under solar irradiation 1 . Several versatile semiconductor photocatalysts, including transition metal oxides, hydroxides, sulfides, phosphates and transition metal dichalcogenides of various particle sizes and shapes and also two dimensional (2D) materials were widely applied for wastewater treatment by degrading organic dyes under sunlight [2][3][4][5] .But the application of photocatalysts suffers from poor photodegradation efficiency, lower chemical stability, and poor exploitation of the solar spectra. Therefore, many efforts have been made to find a photocatalyst system without these shortcomings 6,7 .Graphitic carbon nitride (g-C 3 N 4 ) has been considered a metal-free semiconductor for water splitting, photodegradation of toxic organic pollutants, CO 2 reduction and antibacterial agents to disinfect the antibioticresistant microorganism strains 8,9 .…”
