Photocatalytic degradation effect of malachite green and catalytic hydrogenation by UV–illuminated CeO 2 /CdO multilayered nanoplatelet arrays: Investigation of antifungal and antimicrobial activities

Removal of Malachite Green Dye from Aqueous Solution by Adsorption Using Modified and Unmodified Local Agriculture Waste

“…In this study, for kinetic models have been applied for the experimental data to understand the rate and can be concluded the mechanism of adsorption, which is the first-order, pseudo-second-order, intra-particle diffusion and Boyd. The linear form of Pseudo-first-order model [15,46] is represented by the following equation 10: ln (q e -q t ) = ln q e -K 1 t (10) Where q e and q t refer to the amount of day adsorbent mg/g at equilibrium and at any time, t min and K 1 is the equilibrium rate constant of pseudo-first-order adsorption 1/min. q e which were obtained from the slopes and intercept of the linear plots in Figure 15a of ln(q e -q t ) vs t, the Pseudosecond-order [47].…”

“…Many treatment technologies have been applied to decrease the concentrations dyes from an aqueous media such as adsorption techniques [7], biological treatment [8], decolorization and detoxification [9], photocatalytic degradation [10] and electrochemical degradation [11]. Among treatment strategies, adsorption was regarded to be an effective and preferable method for removing pollutants from wastewater, this method is low cost, the simplicity of design, high removal efficiency, ease of operation and availability.…”

The studies of cytotoxicity and antibacterial activity of composites with ZnO‐doped bioglass

“…In order to improve the mechanical properties of scaffolds based on those polymers and ensure better adherence and proliferation of cells, composites containing calcium phosphates, bioglass or other fillers are used. Recently, the development of a new generation of nanomaterials in the field of photonics and bioelectronics also helps in development of materials with unique biomedical properties …”

Effect of samarium (Sm3+) doping on structural, optical properties and photocatalytic activity of titanium dioxide nanoparticles

“…Among researchers, usage of titanium oxide, zinc oxide, cobalt oxide, etc. as a potential catalyst in UV-VIS and xenon beams becomes a highly effective method to degrade organic dyes [8]. To our knowledge, nano synthesis of rare-earth ions doped TiO 2 particularly Sm 3+ in TiO 2 and their photocatalytic activities under visible light irradiation have never been reported so far.…”
