Tunable sulphur doping in CuFe₂O₄ for the efficient removal of arsenic through arsenomolybdate complex adsorption: kinetics, isothermal and mechanistic studies

Abstract

Arsenic is regarded as a highly toxic element naturally exists in the ground drinking water. Due to its inherent carcinogenic nature, arsenic free water becomes necessary for healthy life. To...

Synergism of Co/Na in BiVO4 microstructures for visible-light driven degradation of toxic dyes in water

“…Common ways to remove the dyes from water are through adsorption and coagulation [3]. However, these methods produce secondary pollutants because dyes are only changed from liquid to solid phase during the adsorption and coagulation [4].…”

“…2 Common ways to remove the dyes from water are through adsorption and coagulation. 3 However, these methods produce secondary pollutants because dyes are only changed from the liquid to the solid phase during adsorption and coagulation. 4 To resolve this issue, an environment-friendly and cost-effective approach is urgently required that can utilize visible light for the removal of organic dyes from aqueous solutions.…”

Surface sensitization of g-C3N4/TiO2via Pd/Rb2O co-catalysts: accelerating water splitting reaction for green fuel production in the absence of organic sacrificial agents

“…The peaks originated at 1635.51 and 3410.39 cm −1 and belonged to the stretching vibrations of the O-H group. 52,53 These peaks confirmed that g-C 3 N 4 and TiO 2 heterostructures could have an interfacial connection. The blocky irregular structure and presence of holes in g-C 3 N 4 allowed an active photocatalytic reaction for hydrogen production.…”

Facile transfer of surface plasmon electrons of Au-NPs to Zn3V2O8surfaces: a case study of sunlight driven H2generation from water splitting

“…In this work it has found that, at high and low pH, hydrogen evolution rate was decreased. Because of highly acidic and basic reaction medium, the stability of photocatalysts was affected and reduced 61 . As a result, activity of photocatalysts for hydrogen production was found to be retarded.…”
