Abstract

Photocatalytic degradation of ofloxacin over the intra-heterostructure of grain-like BixOyClz nanophotocatalyst fabricated via one-pot solution combustion synthesis at low temperatures.

BiOCl/BiOBr Heterojunction with Rich Oxygen Vacancies Induced by Ultraviolet and Its Enhanced Photocatalytic Performance

“…As presented in Figure , the degradation efficiency is seriously suppressed when EDTA‐2Na added, suggesting that the h + plays a crucial role in the degradation process. On the contrary, the degradation efficiency is enhanced compared with the blank experiment after trapping · O 2 – , which may due to the PBQ accelerate the consumption of · O 2 – and promote the separation of photogenerated charge carriers, and thus result in more CBZ oxidized by holes . Furthermore, the spin‐trapping ESR spectrum was further identified to research the reactive oxygen species (ROS) in the present system.…”

Facile One-Pot In Situ Synthesis and Characterization of a Cu2O/Cu2(PO4)(OH) Binary Heterojunction Nanocomposite for the Efficient Photocatalytic Degradation of Ciprofloxacin from Aqueous Solution under Direct Sunlight Irradiation

“…From Figure b, it can be said that at the low level of CP concentration (10 mg L –1 ), the degradation efficiency was similar to that of 20 mg L –1 (98%). Nonetheless, by increasing the CP concentration to 30 and 40 mg L –1 , the photodegradation efficiency was reduced to 84 and 68, respectively, which can be attributed to the decrement of photon absorption and reactive sites in the as-prepared photocatalyst. , …”

Synthesis of a plasmonic AgCl and oxygen-rich Bi24O31Cl10 composite heterogeneous catalyst for enhanced degradation of tetracycline and 2,4-dichlorophenoxy acetic acid

“…19,20 Bi 24 O 31 Cl 10 is said to have high electron mobility making it a good material for photoanode and photocatalysis applications. 14 Bi 24 O 31 Cl 10 is produced through the thermal decomposition of BiOCl at temperatures above 600 C. [21][22][23][24] The compound is a non-stoichiometric oxide of BiOCl with more O and less Cl atoms, it has high chemical and physical stability and a narrow bandgap (2.78 eV) 25 in comparison to BiOCl (3.19-3.6 eV) 23 thereby improving its visible-light absorption potential. The efficiency of a photocatalyst is measured by its (i) absorption in light, (ii) separation of charge and (iii) photocatalytic reaction.…”
