“…Therefore, a logical continuation of the work in [40,41], where the results of the synthesis of ZnSe 2 O 5 were reported, is the synthesis and characterization of similar but simpler nanocrystals of ZnSeO 3 , also obtained in SiO 2 /Si templates. Note that although in recent years several successful attempts have been made to synthesize various types of thin films and nanostructures based on ZnSeO 3 [61][62][63], this work is the first demonstration of the possibility of their synthesis in SiO 2 /Si templates.…”

ZnSeO3 nanocrystals with an orthorhombic structure were synthesized by electrochemical and chemical deposition into SiO2/Si ion-track template formed by 200 MeV Xe ion irradiation with the fluence of 107 ions/cm2. The lattice parameters determined by the X-ray diffraction and calculated by the CRYSTAL computer program package are very close to each other. It was found that ZnSeO3 has a direct band gap of 3.8 eV at the Γ-point. The photoluminescence excited by photons at 300 nm has a low intensity, arising mainly due to zinc and oxygen vacancies. Photoluminescence excited by photons with a wavelength of 300 nm has a very low intensity, presumably due to electronic transitions of zinc and oxygen vacancies.

“…In this case, the advantages of both organic and inorganic semiconductors improved photocatalytic efficiency due to the fast charge separation and transfer. Among different carbon allotropies, graphitic carbon nitride (g-C3N4) has been attracted lots of attention owing to optoelectrical and chemical properties [32][33][34]. Chen et al [35] reported the carboxylic acid -functionalized CdS/g-C3N4 heterojunction as an efficient photocatalyst for sulfamethazine decomposition.…”

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 asprepared 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 ).

Today, high consumption and increasing use of pesticides and chemical fertilizers to control pests of agricultural products, and the entry of these pollutants into the environment, is one of the most important environmental and health problems. Their non-biodegradability, as well as their toxicity and carcinogenicity, have generally made these compounds one of the most dangerous pollutants that cause inevitable pollution of the environmental.Among the various methods used to remove agricultural pesticide residues from the water sources, the adsorption method has received more attention due to its simplicity, cost and higher e ciency.
