“…Therefore, the highest visible light response among nanoparticles was related to TiO 2 /β-Bi 2 O 3 nanocomposite, which is attributed to the synergy effect between TiO 2 and β-Bi 2 O 3 . Therefore, this nanocomposite can be used in photocatalytic reactions due to better performance and more efficient use of light [12] .…”

“…The reusability of the TiO 2 /β-Bi 2 O 3 photocatalyst and the removal efficiency of HCQ contaminant was determined as a promising process and a suitable strategy for photocatalytic degradation of the contaminant in each photocatalytic cycle. For this purpose, after each photocatalytic cycle, the TiO 2 /β-Bi 2 O 3 photocatalyst was separated from the solution and washed several times with distilled water and ethanol, and then dried in an oven at 80 °C for 8 h, and the next step was to remove the HCQ was used [12] . As shown in Figure [19] , it was noticed that upon reusing the nanoparticles for several cycles, the performance of nanoparticles remains the same and there is no remarkable loss in efficiency.…”

“…To date, numerous semiconductor photocatalysts such as TiO 2 , ZnO, C 3 N 4 , WO 3 , Ag 3 PO 4 , and SrTiO 3 have been investigated. However, TiO 2 is still considered a suitable photocatalyst due to its high chemical stability, low- cost, and environmentally friendly [12] , [13] . Due to its wide band gap energy and its low activity in visible light, the use of this nanoparticle is limited.…”

In this research, the cadmium sulfide - graphite carbon nitride (CdS-g-C3N4) nanocomposite was synthesized and characterized by X-ray diffraction (XRD), Field emission scanning electron microscopy (FESEM), energy-dispersive X-ray spectrometer (EDX), and transmission electron microscopy (TEM) techniques. The photocatalytic activity of as-prepared nanocomposite was evaluated in the degradation of ceftriaxone sodium (CTX) antibiotic from aqueous solution under visible light irradiation. The influence of the operational variables such as the amount of photocatalyst (g/L), initial CTX concentration (mg/L), pH, and irradiation time (min) on the photodegradation process was investigated and optimized using response surface methodology (RSM) - central composite design (CCD) model. The maximum degradation percentage (92.55 %) was obtained in the optimal condition, including 0.06 g/L of CdS-g-C3N4 photocatalyst, 15 mg/L of CTX, pH= 10.5, and irradiation time = 81 min. The efficient photocatalytic performance of CdS-g-C3N4 nanocomposite is due to the appropriate alignment of energy levels between the CdS and g-C3N4, which synergistically impact the charge separation and the degradation efficiency of CTX. The kinetics of the photocatalytic degradation process was well described by Langmuir-Hinshelwood’s pseudo-first-order model (kapp = 0.0336 min-1).
