Process enhancing strategies for the reduction of Cr(VI) to Cr(III) via photocatalytic pathway

Simultaneous elimination of toxic dyes, ciprofloxacin and Cr(vi) contents from polluted water: escalating surface plasmon electrons of Ag cocatalysts on BiVO4 microstructures

“…The solution's pH has a considerable impact on the photocatalytic efficiencies owing to the fact that the properties of any catalysts and the targeted pollutants vary with altered pH. 72 The surface of the photocatalysts is surrounded by either negative or positive ions, depending on the acidic and basic media as demonstrated in Fig. 10a.…”

In Situ Construction of a Type II Heterojunction UiO/BMO‐x for Improving the Photocatalytic Reduction of Cr (VI)

“…However, as a harmful heavy metal ion, Cr(VI) can cause cancer, mutations and deformities in living organisms [3] . With the widespread use of Cr, the resulting heavy metal pollution has gradually attracted the attention of people all over the world [4] . It is very important to develop a cost‐effective and reliable technique to remove Cr contamination.…”

Mussel-inspired PDA/Ag nanocomposite catalyst for highly-efficient Cr(vi) removal via visible light-induced reduction and absorption

“…12,13 Due to being green and costeffective, the photocatalytic reduction of Cr(VI) ions is more practical and cleaner compared to chemical reduction, which always exhibits low efficiency, high cost, secondary contamination, and difficulties of catalyst reusability. [14][15][16][17][18] Several reports have well documented the semiconductor-mediated photocatalytic reduction of hexavalent chromium to trivalent chromium and adsorption of Cr(III). [19][20][21][22][23][24] There were also some limitations in these catalysts, such as low biocompatibility, UV-lightdriven, harsh synthesis conditions, and low photocatalytic activities.…”
