Efficient photocatalytic degradation of crystal violet dye and electrochemical performance of modified MWCNTs/Cd-ZnO nanoparticles with quantum chemical calculations

Synthesis of Graphene oxide/Porphyrin Nanocomposite for Photocatalytic Degradation of Crystal Violet Dye

“…The kinetics of CV dye's degradation process was explained by the Langmuir‐Hinshelwood model [4] . The experimental data were best fitted in the pseudo‐first‐order kinetic [equation 4]: $$$\vcenter{\openup.5em\halign{$\displaystyle{#}$\cr {\rm ln}{{{C}_{0}}\over{{C}_{t}}}=K.t\hfill\cr}}$$$ …”

“…It also influences the ecosystem because it quickly enters the body and causes cancer, endocrinal disruptions, dermatitis, irritation to the mucosal membrane, and respiratory dysfunction in human, animal, and aquatic life. [4] The persistence of CV dye in the environment is a major health concern to flora and fauna. [5] The degradation of complex dye molecules in the environment is crucial as persistence may cause disastrous impacts.…”

“…The highly colored dye‐containing effluents from the industries affect the solubility of gases and reduce the light penetration in water sources, which thereby effectively decreases marine life's photosynthetic process. It also influences the ecosystem because it quickly enters the body and causes cancer, endocrinal disruptions, dermatitis, irritation to the mucosal membrane, and respiratory dysfunction in human, animal, and aquatic life [4] .

Synergistically enhanced solar light‐driven degradation of hazardous food colorants by ultrasonically derived MgFe2O4/S‐doped g‐C3N4 nanocomposite: A Z‐scheme system‐based heterojunction approach

“…In contrast, further decrease in percentage degradation with increase in catalyst loading may be attributed to the light scattering and screening effect which can decrease the penetration of light through colorant's solution. [ 126 ] Additionally, the formation of aggregates of the catalyst may also occur at its higher concentration. [ 127 ] Hence, the reduction in the photocatalytic performance is expected.…”

Mechanistic insight into the photocatalytic degradation of organic pollutants and electrochemical behavior of modified MWCNTs/Cu–Co3O4 nanocomposites

“…However, at a given contact time, the reaction mixture with an increased catalyst dose cannot be homogenized properly, and as a result, the active centers become inaccessible, resulting in decreased catalytic activity. 67 At 5 mg EY dye shows low degradation efficiency due to insufficient access to the catalyst surface and light absorption. The degradation of the EY dye was, however, significantly higher in the 10 mg catalyst dose than in the 5, 20, and 30 mg catalyst doses, owing to the availability of more effective active sites as well as more interactions between the dye and catalyst surface, which is more responsible for the dye's enhanced degradation.…”
