MgIn2S4@In2O3 hierarchical tubular heterostructures with expedited photocarrier separation for efficient visible-light-driven antimicrobial activity

MOF-Derived In2O3 Microrod-Decorated MgIn2S4 Nanosheets: Z-Scheme Heterojunction for Efficient Photocatalytic Degradation of Tetracycline

“…The generation of free radicals ( • O 2 – and • OH) during photodegradation was investigated by an ESR method with 5,5-dimethyl-1-pyrroline-N-oxide (DMPO) as a spin-trapping agent. Meanwhile, the 2,2,6,6-tetramethylmethyl group (oxygen) acts as a spin trap to detect the formation of h + during photodegradation. , As illustrated in Figure b, there is no observable DMPO- • O 2 – signal in the dark. Rather, a notable characteristic signal of DMPO- • O 2 – is discovered after 15 min of visible light irradiation, further proving that the MIS In 2 O 3 -(10:1) heterojunction does create • O 2 – during the degradation of TC by visible light irradiation.…”

“…Furthermore, the accession of BQ severely inhibited the performance of MIS-In 2 O 3 -(10:1) in the photocatalytic degradation of TC, suggesting that • O 2 − is the main active substance in the degradation of TC under visible light irradiation.The generation of free radicals ( • O 2 − and • OH) during photodegradation was investigated by an ESR method with 5,5-dimethyl-1-pyrroline-N-oxide (DMPO) as a spin-trapping agent.

As illustrated in Figure9b, there is no observable DMPO-• O 2 − signal in the dark.…”

CaIn2S4–In2O3 hybrid nanofibers with expedited photocarrier separation for fast photocatalytic bacterial inactivation under visible light

“…5-Dimethyl-1-pyrrolidine N -oxide (DMPO) and 2,2,6,6-tetramethylpiperidine (TEMP) were used as the spin-trapping reagents according to a previous report. 34 The samples were also analyzed by photoelectrochemical (PEC) measurements. The samples were coated onto fluorine-doped tin oxide (FTO) glass as the photoelectrode according to the literature.…”

“…Ternary metal sulfides, with the chemical formula AIn 2 S 4 (A = Ca, Mg, Zn, Cd), have attracted considerable attention as candidate photocatalysts due to their intensive visible light absorbance. [31][32][33][34][35][36] In particular, CaIn 2 S 4 with cubic symmetry has a light absorption edge as far as 600 nm and contains non-precious metals with low toxicity, being an ideal photocatalyst for disinfection. [37][38][39] However, as a single-component photocatalyst, CaIn 2 S 4 is subject to a poor photocatalytic level because of the severe photocarrier recombination.…”

Integrated patterned wettability surface for signal expression and efficient photodegradation of multiple water-soluble dyes

“…6 Semiconductor metal oxides have been widely used as photocatalytic materials in the treatment of wastewater, carbon dioxide reduction, and biological disinfection. [7][8][9] Among them, research on TiO 2 has been particularly extensive. 10 In addition, the electrical conductivity and valence band energy of Cu 2 O make it a promising photocatalyst as well.…”
