“…Fe 3 O 4 can also be used as a doping agent for the photocatalysis [ 92 ]. For example, F. Soltani-Nezhad et al [ 93 ] presented a method for producing a GO/Fe 3 O 4 /TiO 2 -NiO-based photocatalyst, which is able to efficiently degrade imidacloprid (pesticide).…”

The growth of industrialization, which is forced to use non-renewable energy sources, leads to an increase in environmental pollution. Therefore, it is necessary not only to reduce the use of fossil fuels to meet energy needs but also to replace it with cleaner fuels. Production of hydrogen by splitting water is considered one of the most promising ways to use solar energy. TiO2 is an amphoteric oxide that occurs naturally in several modifications. This review summarizes recent advances of doped TiO2-based photocatalysts used in hydrogen production and the degradation of organic pollutants in water. An intense scientific and practical interest in these processes is aroused by the fact that they aim to solve global problems of energy conservation and ecology.

“…GO/Fe 3 O 4 /TiO 2 -NiO can be used as an appropriate photocatalyst for the degradation of organophosphorus pesticides in visible light. At pH 9, 0.08 g of GO/Fe 3 O 4 /TiO 2 -NiO can degrade at least 5 mg•L −1 pesticides [90]. Zinc-based materials and an enzyme hybrid system are considered to be effective catalysts for the treatment of refractory pollutants.…”

Imidacloprid is a neonicotinoid insecticide that has been widely used to control insect pests in agricultural fields for decades. It shows insecticidal activity mainly by blocking the normal conduction of the central nervous system in insects. However, in recent years, imidacloprid has been reported to be an emerging contaminant in all parts of the world, and has different toxic effects on a variety of non-target organisms, including human beings, due to its large-scale use. Hence, the removal of imidacloprid from the ecosystem has received widespread attention. Different remediation approaches have been studied to eliminate imidacloprid residues from the environment, such as oxidation, hydrolysis, adsorption, ultrasound, illumination, and biodegradation. In nature, microbial degradation is one of the most important processes controlling the fate of and transformation from imidacloprid use, and from an environmental point of view, it is the most promising means, as it is the most effective, least hazardous, and most environmentally friendly. To date, several imidacloprid-degrading microbes, including Bacillus, Pseudoxanthomonas, Mycobacterium, Rhizobium, Rhodococcus, and Stenotrophomonas, have been characterized for biodegradation. In addition, previous studies have found that many insects and microorganisms have developed resistance genes to and degradation enzymes of imidacloprid. Furthermore, the metabolites and degradation pathways of imidacloprid have been reported. However, reviews of the toxicity and degradation mechanisms of imidacloprid are rare. In this review, the toxicity and degradation mechanisms of imidacloprid are summarized in order to provide a theoretical and practical basis for the remediation of imidacloprid-contaminated environments.

“…In addition, Zhang et al also demonstrated that the hydroxyl radicals ( • OH) generated on core-shell M@TiO 2 played a more important role than superoxide radicals and holes in degradation of RhB under irradiation of UV light, while under the irradiation of visible light holes generated on core-shell M@TiO 2 played a predominant role in degradation of RhB. The effect of shell thickness on core-shell M/S nanocomposite photocatalysts was revealed by Kong et al [93]. In their research, the properties of core-shell Au@Cu 2 O photocatalysts for degradation of MO varied with the Cu 2 O shell thickness in the order 127 nm > 96 nm > 197 nm > 250 nm > 158 nm.…”

“…Ma and other authors [93] obtained nanoplates of WO 3 by topological method using Na 2 WO 4 and HBF 4 and mentioned that intrinsic crystal lattice of tungsten acid plays important role to obtain morphology of final products. The crystal lattice of H 2 WO 4 has (WO 6 ) octahedra layers with normal direction (010) and each layer is linked to each other via hydrogen bonds.…”
