A comprehensive review on sustainable greener nanoparticles for efficient dye degradation

Micelle assisted synthesis of bismuth oxide nanoparticles for improved chemocatalytic degradation of toxic Congo red into non-toxic products

“…6 Among the nanomaterials, metals and metal oxides such as Ag, Au, Cu, ZnO, CuO, TiO 2 , Fe 2 O 3 , Fe 2 O 4 , and Mn 2 O 3 have been widely investigated for degrading a variety of organic dyes. [7][8][9][10][11] Nanocomposites prepared using greener routes were explored as heterogeneous catalysts for effective degradation of organic dyes. [12][13][14][15][16] These metal oxides display good degradation efficiency, but concern over the toxicity of NPs hampered their development.…”

Comparison of membrane immobilized zero-valent iron nanoparticles for RED ME4BL azodye degradation

“…The nanoscale iron particles can agglomerate together swiftly with respect to time. To address this, supports such as nickel, zinc, bentonite, kaolin, rectorite, cellulose, biochar, graphene, and clinoptilolite are added to amplify the stability of iron nanoparticles (Raman and Kanmani, 2016; Kgatle et al, 2021;Thakare et al, 2022). The present study aimed to determine the best immobilization carrier for iron nanoparticles, which in turn will be successful and efficient degradation of the azo dye, RED ME4BL.…”
