Advanced industrialization requires an enormous amount of water, dyes, and chemicals, it continuously releases toxic effluents into the environment water bodies. In textile, paper, leather, other industries, dyes are compounds being used to provide color substances. Among all utilized in dyeing sector, azo contribute about 60 % dyestuffs globally. Synthetic harm aesthetic qualities resources by elevating COD (Chemical oxygen demand) BOD (Biological demand), substances, turbidity, hindering photosynthesis, stifling plant development, contaminating food chain, inducing recalcitrance, accumulation, effectively stimulating toxicity, carcinogenicity, as well mutagenicity. To minimize negative impacts on surroundings, people, natural bodies, wastewater comprising dye pollutants must be removed through eco-friendly technology. As a result, treatment these textile is required before they eliminated surroundings. Physical, chemical, physio-chemical, biological methods among those for treating wastewater. Biological methods, such with bacteria, bacterial enzymes, fungi, plants, were due their environment-friendly cost-effective method. The classification degradation mechanism bacteria addressed this paper.

Disposing of wastewater contaminated with dyes into the environment results in water pollution, which endangers aquatic life and leads to severe health issues for all living species. Zinc oxide-assisted heterogeneous photocatalysis is a significant approach treating dyes. However, its wide energy gap, activated only by UV light, high electron hole pairs recombination rate constrain photocatalytic activities. This review emphasizes impact doping ZnO transition metals non-metals on dye degradation. Both significantly enhances ZnO's photoactivity reducing band shifting absorption edge visible spectrum, producing more oxygen vacancies crystal defects, decreasing conduction electrons valence holes, boosting surface area. The characteristic nanostructures contingent upon their physiological characteristics, including morphology, particle size. It also includes data from literature regarding some dyes' potential degradation pathways mechanisms using ZnO-based photocatalysts. Molecular other reactive species, O2•−, HO2•, H2O2, •OH, produced series reactions, play part degrading effect several operational parameters photodegradation efficiency has been studied detail, solution's pH, concentration, contact time, photocatalyst dose, oxidizing agents, reaction temperature, light intensity. looks at various techniques utilized prepare Future perspectives challenges photocatalysts are discussed.

The extensive use of photocatalysis to address environmental concerns, energy production, and organic transformations has attracted attention in recent decades. SnO/CSO photocatalytic materials were fabricated through a single-step hydrothermal method comprehensively characterized using muti-technique approach demonstrate the physicochemical, morphological, electronic features. According experiments, could remove >96 % acid blue 92 (AB92) azo dye under optimum conditions, with rate constant 2.37 × 10−2 min−1. Furthermore, photocatalyst significantly outperformed commercial TiO2 (P25), reducing CO2 CO CH4 production 10.8 1.18 μmol g−1 h−1, respectively, visible light irradiation. successful direct alkylation amines valuable compounds within 10 min reaction time conversion selectivity >90 was another capability materials, making it good candidate for pharmaceutical synthesis purposes.

In this study, magnetically recyclable NiFe2O4/CoMoS4 heterojunction was synthesized by the one-pot hydrothermal method before being characterized using XRD, FTIR, Raman, TGA, SEM, TEM, BET, EIS, UV–vis DRS, and XPS, respectively. Its bandgap of 2.01 eV aided in absorption more visible light for production reactive radicals. The photocatalyst realized 99.0 % after 60 min when used photo-Fenton degradation methyl orange (MO) dye. enhanced associated with efficient charge separation as indicated Nyquist plots electrochemical impedance spectroscopy (EIS), improved BET surface area, high synergy effect from Fenton photocatalytic processes. composite material has a low crystallite size (4.3 nm) emanating broad diffraction peak compared to pure NiFe2O4 (25 nm). A 50 TOC removal recorded MO reaction. Scavenger tests showed that HO• •O2− were main radicals responsible degradation. revealed minimal electrical energy (13.744 kWh/m3) consumption performance loss five consecutive cycles. Hence, it is inferred these nanomaterials are highly suitable textile wastewater.
