Heterogeneous photo-electro-Fenton degradation of tetracycline through nitrogen/oxygen self-doped porous biochar supported CuFeO2 multifunctional cathode catalyst under visible light

Promoting practical photodegradation application potential of a Bi2WO6-based step-scheme heterojunction under outdoor natural sunlight irradiation

“…Therefore, according to the UV-vis diffuse reflectance spectra in Fig. 9e, the band gap ( E g ) values of BWO and CdS are measured to be 2.81 and 2.23 eV by plotting of ( αhν ) 1/2 and ( αhν ) 2 vs. hν , (Fig. 9f), 31,32 with the corresponding conduction band minimum (CBM) values calculated to be 0.02 and −0.47 eV ( vs. NHE), respectively.…”

“…Tetracycline (TEC) as one of the antibiotics has been widely utilized in human therapy, animal husbandry, and agriculture. 1,2 Unfortunately, the frequent applications could cause abundant accumulation of antibiotics in aqueous environments, which would become a severe potential hazard to human and environmental health. 3,4 Therefore, it is urgent to develop an efficient treatment to eliminate TEC from water.…”

Unusual magnetic behavior of TiO2-doped CuFeO2 crystals (CuFe1−xTixO2) grown by the optical floating zone method

“…Delafossite (CuFeO 2 ) is an inorganic material that in recent years has been used in a wide range of technologies, including the production of new forms of energy, antiviral materials, catalysts, environmental improvement, P–N heterojunction diodes, etc. 1–4 As a multiferroic material with a spin-disoriented structure, CuFeO 2 has a relatively high magnetoelectric effect. 5,6 It belongs to the R 3̄ m space group, and has a layer structure, in which Cu + ions are located between sheets of edge-shared FeO 6 octahedra.…”

Highly porous BiOBr@NU-1000 Z-scheme heterojunctions for synergistic efficient adsorption and photocatalytic degradation of tetracycline

“…Unfortunately, because TC is chemically stable and persistent, it is challenging to remove it from wastewater using traditional pollutant treatment procedures. In recent years, TC has been treated by membrane filtration, 1 adsorption, 2,3 photocatalysis 4,5 and other technologies. In particular, photocatalytic degradation of TC in wastewater and effluents is a green method with high performance, low cost and sustainability.…”
