Enhanced catalytic reduction of p-nitrophenol and azo dyes on copper hexacyanoferrate nanospheres decorated copper foams

Cu-containing polyoxometalate-based melamine in the environmental remediation of toxic organic pollutants

“…Furthermore, organic dyes (especially azo dyes) are another group of toxic materials for environment and living organisms because of the substituted aromatic rings in their structures. 44 Therefore, the catalytic reduction of organic dyes and nitro aromatic compounds is a valuable issue, and has achieved significant importance. The major purpose of these type of reactions is to modify toxic materials into nontoxic ones in order to remove the environmental pollutants and improve the living quality conditions.…”

Flexible Sponge Ball-like Temperature-Responsive Molecularly Imprinted Polymer with Self-Driven “Transformation Recovery” and Mechanism Exploration

“…With the rapid development of industrial technology, p-NP (p-nitrophenol), as one of the most toxic nitrophenols, has been frequently detected in the industrial wastewater in the field of medicine, dyestuffs, chemosynthesis, and pesticides. , The characteristics of difficult natural degradation stability facilitated p-NP gathering in the human body, which could easily cause nausea and inhibit the central nervous system of the human body to make irreversible damage . Due to the strong stability and water solubility, diverse techniques have been employed to eliminate the phenolic compound in industrial wastewater, such as catalytic degradation, , catalytic reduction, discharge plasma, liquid–liquid extraction, etc. However, the techniques mentioned above perhaps destroyed the molecular structure of p-NP.…”

Fast Reduction of 4-Nitrophenol and Photoelectrochemical Hydrogen Production by Self-Reduced Bi/Ti3C2Tx/Bi2S3 Nanocomposite: A Combined Experimental and Theoretical Study

“…As a result, current research focuses on addressing environmental pollution and advancing the exploration of alternative energy sources. − Environmental pollution, especially the pollution of freshwater reservoirs, poses a significant threat to human survival and has emerged as a critical global concern. Among these pollutants, nitrophenol compounds, specifically 4-NP, serve as essential chemical raw materials extensively employed in manufacturing dyes, pesticides, and pharmaceuticals . The release of industrial wastewater containing 4-NP presents a substantial risk due to its toxicity, carcinogenic properties, and the potential to induce allergies and skin inflammation. , Therefore, the reduction of the highly toxic 4-NP to the less harmful 4-AP is essential for both the industrial production of 4-AP and the treatment of wastewater contaminated with 4-NP.…”

The byproduct, 4-AP, has minimal environmental impact and can be reused to produce aniline and paracetamol .…”
