In this study, a TiO2-CeO2 heterostructure was synthesized using a cost-effective hydrothermal technique, suitable for continuous industrial-scale production and environmental remediation applications. The photocatalytic activity of the TiO2-CeO2 heterostructure was examined with MB dye under visible light irradiation. Significantly enhanced photocatalytic activity was observed compared to pure TiO2 nanoparticles.

This article, we present a thorough and straightforward hydrothermal method towards the production of reduced graphene oxide templated MIL-53(Fe) hybrids RGO@MIL-53(Fe). The structural characteristics of created hybrids were identified by using BET, FESEM, powder X-ray diffraction, and FTIR techniques. Methylene blue (MB) dye (a model water pollutant) was used to evaluate H2O2-assisted photo-catalytic efficiency of RGO@MIL-53(Fe).

Photocatalytic degradation proficiency was studied for bromothymol blue dye. Phytochemicals-coated Nickel Oxide nanoparticles demonstrated antibacterial properties against bacteria (gram negative strain of E. coli, Pseudomonas spp. and gram positive strain of Bacillus spp.) by showing highest zone of inhibition (19 mm, 22 mm, 15 mm).the antioxidant activity of the synthesized nanoparticles were also examined and the result show that the fabricated nanoparticles exhibited significant radical scavenging activity.

In this paper, we discuss the efficiency of using a Fe2V4O13 catalyst in a heterogeneous Fenton-like process for the degradation and mineralization of Ind. We examined various factors that influence the reaction, such as the initial pH of the reaction mixture, the initial concentration of hydrogen peroxide, the amount of the Fe2V4O13 catalyst, and the reaction temperature was investigated.

The advanced oxidation processes (AOPs) were commonly used in textile dyeing wastewater treatment due to its ability to rapidly degrade dyed compounds. However, its disadvantage is the limited dispersion of ozone in wastewater. To minimize the disadvantage, it is necessary to improve the gas-liquid phase contact to maximize the dispersion of ozone in the wastewater body.

In the present work, we report on the dye removal efficiency of Cobalt chromite, CoCr2O4 nanoparticles synthesized via the solvothermal method. The obtained CoCr2O4 nanoparticles demonstrated that the dye removal efficiency of CoCr2O4 nanoparticles could be enhanced by a reduction of size or improved water dispersibility.

The organic dyes have beenwidely used in the textile industry for last decades. Nowadays, they have also known as toxic and polluted compounds because of their high persistence in soil sediments and water resources. These chemicals may be degraded to the carcinogens and toxic products under sunlight irradiation, affecting aquatic life and ecosystem.

The synthesis of fluorescent carbon quantum dots (CQDs) and their applications have attracted great attention due to their excellent properties. Especially, the unique visible-light absorption and photo-induced electron transfer properties make CQDs available in photocatalytic degradation of organic dye pollutants in water resources. Herein, we synthesized nondoped CQDs and boron-doped CQDs (B-CQDs) by hydrothermal method and compared their photocatalytic degradation activity of methylene blue (MB) and methyl red (MR) dyes under visible light irradiation.

In this research, a combined photocatalytic and biological treatment is proposed for the elimination of pollutants present in textile wastewater using a natural erionite zeolite (PE) and aluminum oxide (PA) synthesized by the sol-gel method as photocatalysts, and solar radiation. Both catalysts were characterized by XRD, SEM, and EDS. For biological treatment two bacterial consortium were used: BC1 (Escherichia coli N16, Serratia k120, Pseudomonas putida B03 and Enterobacter hormaechei), and consortium BC2 (Escherichia coli N16, Serratia Mc107, Enterobacter N9, Enterobacter hormaechei Mc9).

Decolorization of Reactive Red 3 from aqueous solution by laccase immobilized on the nanocomposite was studied in different conditions (pH, temperature, dye concentration, and reaction time) to investigate the decolorization activity with repeated use and storage. The results indicated that more than 77% of the activity of laccase immobilized systems was retained at the end of 10 cycles. The final decolorization capacity of the immobilized laccase was significantly higher (65%) than that of free laccase (33%) in the chosen optimized conditions (pH 5, 20 ◦ C, 0.
