Endocrine disrupting chemicals are chemicals that interfere with any aspect of the endocrine system. Several natural and synthetic chemicals including pesticides have been identified as endocrine disruptors, which potentially inhibit the reproductive activity of the hormonal system. The pervasive occurrence with trace level concentrations and extensive variety are the reported characteristics of these chemicals. In this study, a dispersive liquid-liquid microextraction method coupled with GC-MS ...

Abstract Herein, the improved visible-light photocatalytic activity towards efficient hydrogen generation using modified P25 (TiO2) has been demonstrated. The P25 has been modified with pure and Phosphorus doped graphitic carbon nitride (CN and PCN) successfully and well-characterized by several analytical techniques. The effect of Phosphorus doping in CN favours to tune the opto-electronic and textural properties. The optimized composite of CN–P25 and PCN–P25 shows nearly twenty-two-fold (920 μ...

Abstract Degradation of wastewater containing recalcitrant pharmaceuticals is one of the emerging problems. Photocatalytic degradation and mineralization of two beta blockers Propranolol (PR) and Atenolol (AT) was investigated in TiO2 suspension. Four commercially available TiO2 samples viz. Aeroxide P25, Hombikat UV 100, Kronoclean 7000 and Merck TiO2 were used in which, Aeroxide TiO2 P25 was found to give best photocatalytic activity for both the pollutants studied under UV light as well as si...

Graphene-carbon nanodots-TiO2 novel ternary composite was developed as visible light photocatalyst. Efficiency and visible light sensitivity of TiO2 for the photodecoloration were enhanced by carbon based photo-sensitizers i.e. carbon nanodots (c-dots) and support i.e. reduced graphene oxide (graphene). The c-dots were prepared by electrophoretic dissolution of graphite electrode in water. The hydrothermal method was used to prepare the composite of graphene, c-dots and TiO2. These were characte...

Among various light-absorbing materials, Copper Zinc Tin Sulphide (CZTS), Selenide (CZTSe) and their alloy structures (CZTSxSe1-x) are viewed as important candidates in thin film solar cell applications. Next development in this field could be a band edge engineering using varied composition layer-structure. Such configuration is expected to absorbed broad spectrum of light and will also provide additional gradient for the efficient charge separation. For such development, however the prior know...

Current research reports the synthesis of reduced graphene oxide (RGO)-TiO 2 nanocomposite by in-situ redox method and graphene oxide by modified hummers method. The ratio of RGO and TiO 2 in the composite was optimized to show best photocatalytic activity for the degradation of targeted pollutants. Optimized (1:10) RGO-TiO 2 nanocomposite was characterized by various techniques viz. X-ray diffraction (XRD), transmission electron microscopy (TEM), thermogravimetric analysis (TGA), Brunauer–Emmet...

Study Ag-TiO 2 composite has been synthesized by photodeposition method. The prepared composite has been characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and diffuse reflectance spectroscopy (DRS). The effect of Ag deposition on TiO 2 has been tested for photocatalytic degradation of azo dye, Evans Blue (EB). The comparison of different advanced oxidation processes (AOP) such as (i) Only Ag-TiO 2 (ii) only UV (iii) UV + TiO 2 (iv) UV + Ag-TiO 2 (v) UV + Ag-TiO 2 +H 2 ...
