Fast photodegradation of antibiotics and dyes by an anionic surfactant-aided CdS/ZnO nanodispersion

Abstract

Photocatalytic technology has broad applications in energy and environmental science. In this study, we synthesized a type II heterojunction CdS/ZnO nanodispersion by means of one-pot precipitation. Different from previous studies,...

Upcycling plastic wastes into high-performance nano-MOFs by efficient neutral hydrolysis for water adsorption and photocatalysis

“…S10†). A previous report 50 revealed a high band gap value of ZnO (3.37 eV) only responding to ultraviolet light. These results indicate that the coupling of MOFs with narrow bandgaps and ZnO enhances the photocatalytic properties of the OP-MOFs with relatively low purities and BET surface areas.…”

La/Fe bimetallic MOF-derived p-LaFeO3/n-CdS heterojunction: efficient photocatalytic degradation of organic contaminants and adsorption isotherms

“…Eqn (6) and (7) of the Langmuir adsorption isotherm can be expressed as follows:and its linearized form is represented in equation: 7 …”

“…Among them, photocatalysis employing semiconducting materials is considered a promising and eco-friendly treatment approach for the removal of toxic organic and inorganic pollutants. [5][6][7][8] Among various semiconducting materials, TiO 2 is highly promising owing to its better photoactivity, stability, affordability, and eco-friendliness. 9,10 TiO 2 can absorb light exclusively in the UV region owing to its large band gap energy (3.2 eV), which limits its applicability in the visible spectrum.…”

Visible Light-Driven Photocatalytic Degradation of Tetracycline Using p-n Heterostructured Cr2O3/ZrO2 Nanocomposite

“…Semiconductor photocatalysis which utilizes solar energy has drawn significant attention in the global scientific community due to its great potential in the search for better solutions to current environmental and energy issues [15]. This has led to the development of several nanomaterials like g-C 3 N 4 , FeAl 2 O 4 , Cu 2 O, Bi 2 WO 6 , CdS-N/ZnO, etc., for the photocatalytic degradation of various organic pollutants under visible light [16][17][18][19][20]. However, all these methods have limitations, such as high costs, slow degradation rates, UV-active materials, and reusability issues.…”
