Green synthesis of Cu-doped ZnO nanoparticles and its application for the photocatalytic degradation of hazardous organic pollutants

Fe3O4@SiO2@TiO2@PDA Nanocomposite for the Degradation of Organic Materials

“…Amidst many processes applied to treat effluents, photodegradation using catalysts like ZnO, NiO-CGYO (nickel based yttria and gadolinia co-doped ceria), NiO, etc. has attracted attention as the most promising method, due to its simple operation, low cost, high efficiency, and lack of secondary pollution [8][9][10]. In recent years, metal oxides, metal nitrides, and metal sulfides have been regarded as among the most popular materials in various applications such as energy storage, hydrogen production, and environmental purification, due to their excellent optical, electronic, photocatalytic, and biological properties [11][12][13][14].…”

Recent advances in photocatalytic remediation of emerging organic pollutants using semiconducting metal oxides: an overview

“…Biomolecules in plants, such as carbohydrates, proteins, and coenzymes, can reduce metal salts to nanoparticles (Singh et al 2018). One example is the green synthesis of CuO and Cu-metal oxide nanoparticles using plant extracts for copper salt reduction (Akintelu et al 2020;Karthik et al 2022). The critical drawbacks of biological components for green synthesis over other methods are that it is difficult to achieve the optimal nanoparticle size and morphology, and a significantly lower yield is obtained (Stankic et al 2016).…”

A review on bio-electro-Fenton systems as environmentally friendly methods for degradation of environmental organic pollutants in wastewater

“…13,31,33,34 Despite its advantages such as without of the need for storage and transportation of H 2 O 2 , reduced sludge production compared with the Fenton process, and high efficiency regarding the removal of a wide range of environmental organic contaminants due to the need for high electricity, this process requires high operational costs, which limit its practical application. 35–37 Furthermore, in other technologies such as photocatalysis processes under UV-light irradiation, 22,38 an external energy source has been used to decompose organic pollutants, which this has attracted the researchers' attention to the use of photocatalytic processes under sunlight irradiation in recent years. 39–41 In these processes with potential applications, different photocatalysts with high photocatalytic activities are used.…”
