g-C3N4 Based Photocatalyst for the Efficient Photodegradation of Toxic Methyl Orange Dye: Recent Modifications and Future Perspectives

Molecules, Journal Year: 2023, Volume and Issue: 28(7), P. 3199 - 3199

Published: April 4, 2023

Industrial effluents containing dyes are the dominant pollutants, making drinking water unfit. Among dyes, methylene orange (MO) dye is mutagenic, carcinogenic and toxic to aquatic organisms. Therefore, its removal from bodies through effective economical approach gaining increased attention in last decades. Photocatalytic degradation has ability convert economically complex molecules into non-toxic smaller species via redox reactions, by using photocatalysts. g-C3N4 a metal-free n-type semiconductor, typical nonmetallic non-toxici polymeric photocatalyst. It widely used photocatalytic materials, due easy simple synthesis, fascinating electronic band structure, high stability abundant availability. As photocatalyst, major drawbacks limited efficiency separating photo-excited electron–hole pairs, separated charge recombination, low specific surface area, absorption coefficient. In this review, we report recent modification strategies adopted for efficient photodegradation of MO dye. The different approaches, such as nanocomposites heterojunctions, well doping defect introductions, briefly discussed. mechanism future perspectives This review paper will predict fabrication an g-C3N4-based photocatalyst

Pharmaceutical and Personal Care Products in Different Matrices: Occurrence, Pathways, and Treatment Processes

Water, Journal Year: 2021, Volume and Issue: 13(9), P. 1159 - 1159

Published: April 22, 2021

The procedures for analyzing pharmaceuticals and personal care products (PPCPs) are typically tedious expensive thus, it is necessary to synthesize all available information from previously conducted research. An extensive collection of PPCP data the published literature was compiled determine occurrence, pathways, effectiveness current treatment technologies removal PPCPs in water wastewater. Approximately 90% papers originated Asia, Europe, North American regions. incomplete different wastewater processes widely reported, thus resulting occurrence compounds various environmental compartments. Caffeine, carbamazepine, diclofenac, ibuprofen, triclosan, triclocarban were among most commonly reported detected solid matrices. Trace concentrations also on plants animal tissues, indicating bioaccumulative properties some compounds. A significant lack studies regarding presence plant samples identified review. Furthermore, there still knowledge gaps ecotoxicity, sub-lethal effects, effective PPCPs. this study can be used devise a more research paradigm guidelines management.

Synthesis of porphyrin porous organic polymers and their application of water pollution treatment: A review

Environmental Technology & Innovation, Journal Year: 2022, Volume and Issue: 29, P. 102972 - 102972

Published: Nov. 25, 2022

With the advance of society and industrialization, a large number organic inorganic pollutants in water cause harm to humans environment. Therefore, development effective pollutant removal methods materials is urgently needed. Porous polymers (POPs) are emerging porous formed by polymerization different structured building blocks. Adjustable pore size structure, specific surface area, high porosity for POPs provide platform study water. The thermal stability insoluble skeleton make them highly stable water, not easily decomposed, produce secondary degradation products. Porphyrins have conjugation systems their molecular centers strongly coordinated with metal ions, which been widely studied applied recent years. Porphyrin (Py-POPs) combine advantages porphyrins photosensitivity. Based on above, researchers enthusiastically working Py-POPs. In this review, we summarized research progress Py-POPs Firstly, introduced structures linkage bonds that up preparation Then application field adsorption green photocatalytic was presented. Finally, prospects challenges further were discussed.
