Efficient activation of peroxydisulfate by g-C3N4/Bi2MoO6 nanocomposite for enhanced organic pollutants degradation through non-radical dominated oxidation processes

Mechanism insight into the photocatalytic degradation of fluoroquinolone antibiotics by the ZIF-8@Bi2MoO6 heterojunction

“…The low photocatalytic activity of these materials is due to their high recombination of photo-excited electrons and holes, which is consistent with those reported in the literature for g-C 3 N 4 /Bi 2 MoO 6 /vis. 20 The OFX degradation efficiency in the simultaneous presence of the catalyst, Na 2 S 2 O 8 , and light irradiation was 20.45% for ZIF-8, 64.91% for Bi 2 MoO 6 , and 96.36% for BIZ (Fig. 4(a)).…”

“…18 Among persulfates (i.e., Na 2 S 2 O 8 , K 2 S 2 O 8 , (NH 4 ) 2 S 2 O 8 , and KHSO 5 ), Na 2 S 2 O 8 is frequently employed because of its many advantages such as low cost, high stability, ease of transport, and high solubility. 19,20 Among the activation methods, photocatalysis is widely studied because it is low cost, feasibility, high efficiency, and environmental-friendliness. In general, an ideal photocatalyst should have a narrow bandgap energy, be able to work under visible light and therefore possibly utilize the abundant natural sunlight.…”

Amorphous CoSx decorated Cd0.5Zn0.5S with a bulk-twinned homojunction for efficient photocatalytic hydrogen evolution

“…Hydrogen (H 2 ) energy is considered one of the most valuable clean energy sources to replace fossil fuels for achieving carbon neutralization due to its high energy density. [1][2][3] Since 1972, solar-driven photocatalytic water splitting has been regarded as one of the most promising methods to realize sustainable H 2 production. 4,5 In recent decades, relevant research has focused on designing and synthesizing highly active photocatalysts.…”

Preparation and performance of novel Ni-doped iron oxychloride with high singlet oxygen generation

“…8–17 Besides these free radicals directly decomposed from oxidizing agents, some free radicals with comparatively lower oxide electrode potential like singlet oxygen ( 1 O 2 ) and the carbonate radical (˙CO 3 − ) with much more disordered reaction conditions and more complex mechanisms which have arisen as a new kind of active substance are also being paid great attention. 1,18,19…”

“…) with much more disordered reaction conditions and more complex mechanisms which have arisen as a new kind of active substance are also being paid great attention. 1,18,19 Among them, as a kind of reactive oxygen species (ROS), singlet oxygen ( 1 O 2 ) also has broad applications in environmental treatment because of its excellent oxidation capacity and high selectivity. 20,21 As a special kind of oxidizing agent, singlet oxygen can realize the use of molecular oxygen for the degradation of organic contaminants.…”
