Catharanthus roseus leaf extract mediated Ag-MgO nanocatalyst for photocatalytic degradation of Congo red dye and their antibacterial activity

Enhanced Congo Red Adsorption and Photo-Fenton Oxidation over an Iron-Impeded Geopolymer from Ferruginous Kaolinite: Steric, Energetic, Oxidation, and Synergetic Studies

“…CR is widely used in the paper, cosmetics, leather, and textile industries. 5 , 8 However, the seepage of dissolved CR molecules into water resources induces marked toxicity and environmental effects. 5 , 8 The presence of CR molecules depletes dissolved oxygen in the water and its distribution during photosynthesis, thereby having a negative impact on the aquatic ecosystem.…”

“… 5 , 8 However, the seepage of dissolved CR molecules into water resources induces marked toxicity and environmental effects. 5 , 8 The presence of CR molecules depletes dissolved oxygen in the water and its distribution during photosynthesis, thereby having a negative impact on the aquatic ecosystem. 9 Moreover, there are several health-related side effects associated with CR pollution, including respiration problems, vomiting, carcinogenic and mutagenic effects, and diarrhea.…”

“…14,15 Such advanced oxidation techniques facilitate considerable degradation of dyes and the mineralization of dye molecules into environmental end products in the presence of sunlight or artificial light sources. 5,16 Several factors control the suitability of the adsorbent and catalyst used during the oxidation processes, including recyclability, biodegradability, bandgap energy, recombination rate, thermal stability, safety, fabrication cost, and adsorption capacity. 16 The development of new structures with enhanced adsorption and advanced oxidation properties based on natural precursors is strongly recommended owing to the cost and environmental considerations.…”

“…Wastewater contains various inorganic (heavy metals, ammonium, phosphate, nitrate, and sulfate) and organic pollutants (dyes, pharmaceutical residuals, and pesticides). All of the listed chemicals are toxic to humans and other living species and have a detrimental impact on the environment and ecosystem. , However, among these, synthetic dyes are vital aromatic compounds that are used in several industries. Approximately 10–15% of the produced quantity (7 × 10 5 tons) is discharged into the surrounding water bodies as untreated and nondegradable industrial wastewater, inducing varying side effects. , …”

Preparation and Characterization of Magnesium Oxide Nanoparticles and Its Application for Photocatalytic Removal of Rhodamine B and Methylene Blue Dyes

“…Apart from the synthesis of nanoparticles, ZrO 2 nanoparticles and mixed MgO-ZnO nanoparticles were utilized for photocatalysis of dyes [20,21]. Also, Congo red and other dyes are also effectively removed by photocatalysis [22,23]. For the analysis of literature, K. alvarezii has not been studied for the synthesis of MgO nanoparticles.…”
