“…Many reports have been performed regarding the usage of MOFs as catalysts in different reactions, like the reduction of nitrophenols, dyes, and Sonogashira-Hagihara reactions. [111][112][113][114][115] In 2023, Nishat and co-workers 116 reported Cu-β-CD-MOF followed by vapor diffusion of MeOH. This catalyst was used for nitroaromatic reduction and acted as a superior catalytic reducing nitro compound in below four min.…”

Regarding the incremental shortage of water resources, wastewater treatment is essential for guarding the ecosystem and the sufficient usage of water resources. Freshwater, a vital item of life for humans and animals, is in danger because of the existence of destructive pollutants, such as p‐nitrophenol (p‐NP), and organic azo dyes, leading to water pollution. Among environmental pollution, water pollution has been recognized as one of the important threat agents in charge of many illnesses in humans. Nitrophenols contain high stability and solubility in water, which causes health risks. It is essential to change these harmful chemicals into healthy materials to have a safe life on the globe. Nitro compounds obtained from industrial wastewater are a severe threat to human being health and living organisms. Hence, designing green strategies and environment‐friendly catalysts to reduce toxic contaminants such as nitro compounds and dyes is a considerable challenge. One technique to overcome this crisis is the catalytic hydrogenation of nitro compounds to the amines, which are invaluable and non‐toxic materials. Reducing nitroarenes can be synthesized the amines, vital intermediates in organic and biological chemistry. Designing green strategies in nitro reduction processes for synthetic organic chemists is a great challenge. The nitroarene reduction reaction is a very efficient, reliable, and environmentally friendly method for synthesizing amines. Cyclodextrin (CD) can be applied as an effective catalyst in many aqueous organic reactions. Their derivatives have exhibited outstanding performance in water‐mediated organic synthesis and are now of ongoing attraction to many scientists in various fields. CDs show better catalytic activity and selectivity due to their particular geometry and structural interactions. CDs catalyzed reactions have been getting significant attention recently due to their low toxicity, biodegradability, economically and eco‐friendly behavior. Many reports are available in the literature on CDs material considered promising catalysts in reducing nitro compounds. This review article focuses on the use of β‐CD catalyst systems as valuable catalysts in the hydrogenation of nitroarenes and overviews articles up to 2023.

“…Despite the limitations with aforementioned methods, it was proven that reduction of azodye into harmless products utilizing Sodium Borohydride (NaBH 4 ) could be efficiently inducted in the presence of a convenient catalyst. This approach is distinguished by its ease of use, time saving, efficient conversion rates and lack of sludge [ 12 – 19 ].…”

One of the biggest issues affecting the entire world currently is water contamination caused by textile industries’ incapacity to properly dispose their wastewater. The presence of toxic textile dyes in the aquatic environment has attracted significant research interest due to their high environmental stability and their negative effects on human health and ecosystems. Therefore, it is crucial to convert the hazardous dyes such as methyl orange (MO) azo dye into environmentally safe products. In this context, we describe the use of Copper Nitroprusside Chitosan (Cu/SNP/Cts) nanocomposite as a nanocatalyst for the chemical reduction of azodyes by sodium borohydride (NaBH4). The Cu/SNP/Cts was readily obtained by chemical coprecipitation in a stoichiometric manner. The X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and Fourier transform infrared (FT-IR) spectroscopy were applied to investigate chemical, phase, composition, and molecular interactions. Additionally, Scanning electron microscope (SEM) was used to examine the nanomaterial's microstructure. UV–vis spectroscopy was utilized for studying the Cu Nitroprusside Chitosan's catalytic activity for the reduction of azodye. The Cu/SNP/Cts nanocomposite demonstrated outstanding performance with total reduction time 160 s and pseudo-first order constant of 0.0188 s−1. Additionally, the stability and reusability study demonstrated exceptional reusability up to 5 cycles with minimal activity loss. The developed Cu/SNP/Cts nanocomposite act as efficient nanocatalysts for the reduction of harmful Methyl orange azodye.

“…[13][14][15][16][17][18] Due to their good biocompatibility, persistent porosity, and strong crystallinity, CD-MOFs have prospective applications in a variety of fields. [19][20][21][22][23][24] In addition, MOFs have been established to serve as catalysts for propellants, solid fuels, and the components of detonating charges. [25][26][27] For instance, in order to hasten the thermal decomposition of ammonium perchlorate, MOFs with energetic ligands were investigated as combustion promoters.…”
