The effects of the textile industry on the environment are now a major global concern. Many dyestuffs are toxic, carcinogenic, and non-biodegradable, which are being used in large amounts in dyeing and printing processes. Electron beam radiation is a wastewater treatment technology that is more effective than the conventional methods used for treatment of dye wastewater. The current paper presents a review on the recent advances, applications, and efficiency of electron beam irradiation and its combination with other textile effluent decolorization techniques. The purpose of this study is to accurately characterize the textile effluent electron beam treatment, to reveal its main issues, and to offer suggestions for additional growth and research. The current work examines the generation of reactive species by electron beams and their interactions with dye molecules. The mechanisms of decolorization and degradation caused by electron beam radiation have been thoroughly studied. This study also highlights the use of electron beam irradiation for the preparation of different materials and their applications in dye removal from textile effluents. This study also focuses on the use of an integrated approach of electron beam irradiation in combination with other treatment techniques for the removal of dyes from textile effluents.

“…Consequently, the fusion of superhydrophobicity with the photocatalytic decomposition of organic compounds has garnered considerable attention from the research community in recent years [26][27][28][29]. Semiconductor oxides such as TiO 2 [30], SnO 2 [31], ZnO [32], NiO [33], Cu 2 O [34], and CuO [35] are extensively utilized as photocatalysts in the degradation of various pollutants, encompassing dyes, organic contaminants, natural organic substances, and pharmaceutical compounds. Notably, copper oxide (CuO), featuring a band gap within the range of 1.2~2.1 eV, stands out as a critical p-type semiconductor renowned for its catalytic, optical, antimicrobial, and cost-efficient attributes [36][37][38].…”

The exceptional corrosion resistance and combined physical and chemical self-cleaning capabilities of superhydrophobic photocatalytic coatings have sparked significant interest among researchers. In this paper, we propose an economical and eco-friendly superhydrophobic epoxy resin coating that incorporates SiO2@CuO/HDTMS nanoparticles modified with Hexadecyltrimethoxysilane (HDTMS). The application of superhydrophobic coatings effectively reduces the contact area between the metal surface and corrosive media, leading to a decreased corrosion rate. Additionally, the incorporation of nanomaterials, exemplified by SiO2@CuO core–shell nanoparticles, improves the adhesion and durability of the coatings on aluminum alloy substrates. Experimental data from Tafel curve analysis and electrochemical impedance spectroscopy (EIS) confirm the superior corrosion resistance of the superhydrophobic modified aluminum alloy surface compared to untreated surfaces. Estimations indicate a significant reduction in corrosion rate after superhydrophobic treatment. Furthermore, an optical absorption spectra analysis of the core–shell nanoparticles demonstrates their suitability for photocatalytic applications, showcasing their potential contribution to enhancing the overall performance of the coated surfaces. This research underscores the promising approach of combining superhydrophobic properties with photocatalytic capabilities to develop advanced surface modification techniques for enhanced corrosion resistance and functional properties in diverse industrial settings.
