In this work, we have presented a very detailed review of the different classification of azo dyes as a function of the number of azo groups and the appropriate functional groups. Then we pointed out some chemical properties of these dyes such as reactivity, isomerization and tautomerism and listed. In the following, we have summarized some recent syntheses of azo dyes and the mechanism of azo dye/polymer conjugation. Finally, we indicate the principle of Gewald's reaction and its application to the synthesis of new azo dyes.

“…Azo dyes are the most significant artificial colorants that are widely employed in the production of textiles, prints, and papers, among other things [23]. Azo dyes dangerous influence on people and the environment and these effects require prompt treatment of effluents containing azo dyes to separate them or transform them into helpful and safe compounds [24]. Additionally, when azo dyes' molecular weight grew, the dispersion of colors in water doubled.…”

Azo compounds are a class of organic materials that have the group R-N=N-R' where the substitution group R and R' are aromatic or heterocyclic sides. The azo compounds have a variety of applications including dyes, pigments, and pharmaceuticals. The preparation and characterization of different azo compounds is an important area of research in organic synthesis. The azo compound synthesis typically involves the diazotization process for coupling between an aromatic amine and another aromatic compound containing an activating group such as -OH, -NH2, or -NR2. The reaction conditions must be carefully controlled to prevent side reactions, such as the formation of unwanted byproducts. Once synthesized, azo compounds can be characterized using a variety of techniques including UV-Vis spectroscopy, NMR spectroscopy, and mass spectrometry. UV-Vis spectroscopy is a commonly used technique for characterizing azo compounds. The absorption spectrum of an azo compound typically exhibits a strong absorption band in the visible region due to the delocalized π-electrons in the azo group. While in FTIR, the loss of the amine peak and showing a weak peak at about 1550 cm−1forthe (N=N) group, indicates the presence of Azo. The preparation and characterization of different azo compounds is a significant field of research in organic chemistry, which are applied as acid and base indicators, food coloring, optical switches, liquid crystal and in medicine. By carefully controlling the synthesis conditions and using a variety of characterization techniques, researchers can gain a better understanding of the properties and applications of these compounds.

“…Non-metal doping can reduce the recombination rate and enhance the efficiency of this semiconductor photocatalyst via a redshift of band gap edges [10,11]. Unless abated, azo dyes such as Eriochrome Black T (EBT) will pose a costly or laborious remediation process [6] and considerable health risk to human and aquatic life [12,13] due to their complex molecular structure, chemical stability, non-biodegradable and high solubility in water [14]. Because they are commonly used in textiles, biological staining, research and teaching laboratories, coupled with the risk of uncontrolled release, these dyes have increasingly become environmentally important [15,16].…”

Zinc oxide-mediated photocatalysis is a promising alternative to TiO2 photocatalysis, especially for the purpose of removal of recalcitrant organic dye pollutants. Highly crystalline, nanoscopic carbon-doped ZnO was successfully synthesized via combined precipitation and mechanochemical approach and characterized using x-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive x-ray (EDX) and Fourier transform infrared (FTIR) spectrometry. The obtained photocatalysts depict plate-like morphology and hexagonal wurtzite structure. The XRD, SEM, and FTIR analyses were in good agreement with EDX results. The 5wt % C-doped ZnO showed remarkable visible light-photocatalytic activity based on the degradation of Eriochrome Black T (EBT), and exhibits the best point of zero charge (pHpzc) for a favorable adsorption equilibrium. This degradation process was optimized at 97 % using response surface methodology (RSM) using a 0.1 g C-ZnO, 5.00 mg/L EBT and pH 11. The associated kinetic data fit the pseudo-first-order kinetic model. The resulting C-ZnO was a p-type with a good pH at zero-point charge that permits the substantial removal of EBT by C-doped under visible light irradiation over a wide range of initial pH.
