Facile synthesis of N/B-double-doped Mn₂O₃ and WO₃ nanoparticles for dye degradation under visible light

Fabrication, functionalization and performance of doped photocatalysts for dye degradation and mineralization: a review

“…For example, Shah et al (2019) have recently fabricated N-doped and N-B-co-doped WO 3 and Mn 2 O 3 nanoparticles (NPs) following a precipitation and hydrothermal procedure. Shah et al (2019) reported excellent photocatalytic performances of the new nanomaterial in that the codoping of the WO 3 and Mn 2 O 3 had led to high photocatalytic activity in contrast to the photodegradation of methylene blue that reached nearly three and half times greater for in the case of the W-based materials and three times more in the case of the Mn-based materials in relation to their pure state compounds, respectively. In a study reported earlier, Movahed et al (2018) had shown that a novel, effective and reusable Cu X /N-PC composite could be employed as a heterogeneous photocatalyst for the degradation of methyl orange and rhodamine B and in the C-H activation of formamides.…”

Piezo‐photocatalytic activity of mechanochemically synthesized BiVO4 for dye cleaning

“…During the piezo-photocatalysis experiment, scavengers such as ethylenediaminetetraacetic acid, p-benzoquinone (p-BQ), and isopropanol were separately added to the dye solution so as to capture the various active species such as holes (h + ), superoxide radical (•𝑂 − 2 ), and hydroxyl radical (•OH), respectively. 53,54 Figure 8D clearly shows that BQ scavenger which scavenge O .− 2 radicals has drastically influenced the piezo-photocatalytic activity. The scavenger test affirms that O .− 2 radical was the main active species during the piezo-photocatalytic activity.…”
